How to Write Topic Sentences | 4 Steps, Examples & Purpose

Published on July 21, 2022 by Shona McCombes . Revised on June 5, 2023.

Every paragraph in your paper needs a topic sentence . The topic sentence expresses what the paragraph is about. It should include two key things:

• The  topic of the paragraph
• The central point of the paragraph.

After the topic sentence, you expand on the point zwith evidence and examples.

To build a well-structured argument, you can also use your topic sentences to transition smoothly between paragraphs and show the connections between your points.

Writing strong topic sentences, topic sentences as transitions between paragraphs, topic sentences that introduce more than one paragraph, where does the topic sentence go, frequently asked questions about topic sentences.

Topic sentences aren’t the first or the last thing you write—you’ll develop them throughout the writing process. To make sure every topic sentence and paragraph serves your argument, follow these steps.

Step 1: Write a thesis statement

The first step to developing your topic sentences is to make sure you have a strong thesis statement . The thesis statement sums up the purpose and argument of the whole paper.

Thesis statement example

Food is an increasingly urgent environmental issue, and to reduce humans’ impact on the planet, it is necessary to change global patterns of food production and consumption.

Step 2: Make an essay outline and draft topic sentences

Next, you should make an outline of your essay’s structure , planning what you want to say in each paragraph and what evidence you’ll use.

At this stage, you can draft a topic sentence that sums up the main point you want to make in each paragraph. The topic sentences should be more specific than the thesis statement, but always clearly related to it.

Topic sentence example

Research has consistently shown that the meat industry has a significant environmental impact .

Step 3: Expand with evidence

The rest of the paragraph should flow logically from the topic sentence, expanding on the point with evidence, examples, or argumentation. This helps keep your paragraphs focused: everything you write should relate to the central idea expressed in the topic sentence.

In our example, you might mention specific research studies and statistics that support your point about the overall impact of the meat industry.

Step 4: Refine your topic sentences

Topic sentences usually start out as simple statements. But it’s important to revise them as you write, making sure they match the content of each paragraph.

A good topic sentence is specific enough to give a clear sense of what to expect from the paragraph, but general enough that it doesn’t give everything away. You can think of it like a signpost: it should tell the reader which direction your argument is going in.

To make your writing stronger and ensure the connections between your paragraphs are clear and logical, you can also use topic sentences to create smooth transitions. To improve sentence flow even more, you can also utilize the paraphrase tool .

As you write each topic sentence, ask yourself: how does this point relate to what you wrote in the preceding paragraph? It’s often helpful to use transition words in your topic sentences to show the connections between your ideas.

Emphasize and expand

If the paragraph goes into more detail or gives another example to make the same point, the topic sentence can use words that imply emphasis or similarity (for example, furthermore , indeed , in fact , also ).

Indeed , cattle farming alone is responsible for a large proportion of greenhouse gas emissions.

Summarize and anticipate

If the paragraph turns to a different aspect of the same subject, the topic sentence can briefly sum up the previous paragraph and anticipate the new information that will appear in this one.

While beef clearly has the most dramatic footprint, other animal products also have serious impacts in terms of emissions, water and land use.

Compare and contrast

If the paragraph makes a comparison or introduces contrasting information, the topic sentence can use words that highlight difference or conflict (for example, in contrast , however , yet , on the other hand ).

However , the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

You can also imply contrast or complicate your argument by formulating the topic sentence as a question.

Is veganism the only solution, or are there more sustainable ways of producing meat and dairy?

Sometimes you can use a topic sentence to introduce several paragraphs at once.

All of the examples above address the environmental impact of meat-eating versus veganism. Together, they make up one coherent part of a larger argument, so the first paragraph could use a topic sentence to introduce the whole section.

In countries with high levels of meat consumption, a move towards plant-based diets is the most obvious route to making food more sustainable. Research has consistently shown that the meat industry has significant environmental impacts.

The topic sentence usually goes at the very start of a paragraph, but sometimes it can come later to indicate a change of direction in the paragraph’s argument.

Given this evidence of the meat industry’s impact on the planet, veganism seems like the only environmentally responsible option for consumers. However, the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

In this example, the first sentence summarizes the main point that has been made so far. Then the topic sentence indicates that this paragraph will address evidence that complicates or contradicts that point.

In more advanced or creative forms of academic writing , you can play with the placement of topic sentences to build suspense and give your arguments more force. But if in doubt, to keep your research paper clear and focused, the easiest method is to place the topic sentence at the start of the paragraph.

A topic sentence is a sentence that expresses the main point of a paragraph . Everything else in the paragraph should relate to the topic sentence.

Topic sentences help keep your writing focused and guide the reader through your argument.

In an essay or paper , each paragraph should focus on a single idea. By stating the main idea in the topic sentence, you clarify what the paragraph is about for both yourself and your reader.

The topic sentence usually comes at the very start of the paragraph .

However, sometimes you might start with a transition sentence to summarize what was discussed in previous paragraphs, followed by the topic sentence that expresses the focus of the current paragraph.

Let’s say you’re writing a five-paragraph  essay about the environmental impacts of dietary choices. Here are three examples of topic sentences you could use for each of the three body paragraphs :

• Research has shown that the meat industry has severe environmental impacts.
• However, many plant-based foods are also produced in environmentally damaging ways.
• It’s important to consider not only what type of diet we eat, but where our food comes from and how it is produced.

Each of these sentences expresses one main idea – by listing them in order, we can see the overall structure of the essay at a glance. Each paragraph will expand on the topic sentence with relevant detail, evidence, and arguments.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

Writing Topic Sentences — Purpose, Structure, and Examples

What is a topic sentence?

A topic sentence in academic writing identifies how a body paragraph relates to the overall purpose of an essay stated in the thesis statement . Topic sentences are usually at the beginning of a paragraph and identify the paragraph’s controlling idea.

While an essay’s thesis statement identifies the point of the essay in its entirety, the topic sentence has a much narrower focus, as it relates only to the paragraph in which it is located.

What is the purpose of a topic sentence?

The purpose of a topic sentence is to inform the reader of the main idea of the paragraph and how it connects to the overall objective of the essay. An effective topic sentence accomplishes one or more of the following:

Makes a claim

Supports other claims made in the paper

Identifies the purpose of the rest of the paragraph

Relates the paragraph to the purpose of the paper

Precedes information that defends a claim

How to write a topic sentence

To write a topic sentence, incorporate the following guidelines:

Determine the thesis of the essay.

Identify the main supports that help prove the thesis.

Use each main support to structure a topic sentence for each paragraph.

Compose a sentence that answers the following questions:

What will the paragraph prove?

How does the paragraph connect to the thesis?

Where is the topic sentence in a paragraph?

Topic sentences can be placed at the beginning or end of a paragraph.

Although it does not need to be the first sentence, the topic sentence should be placed at the beginning of the paragraph so the reader can quickly identify the purpose of the paragraph.

While not a common placement for a topic sentence, some writers use topic sentences at the end of a paragraph. Writers who choose this method want the reader to deduce the main point of the paragraph by presenting the evidence first.

Topic sentence examples

The following list identifies topic sentences based on the provided thesis statements for five-paragraph essays:

Thesis Statement: Capital punishment should be banned because it is inhumane, unconstitutional, and ineffective at deterring crime.

Support Paragraph 1 Topic Sentence: The inhumane nature of the death penalty proves it should be abolished.

Support Paragraph 2 Topic Sentence: Capital punishment should be outlawed because it violates the Constitution.

Support Paragraph 3 Topic Sentence: Because the death penalty does not effectively deter criminal behavior, states should not continue to use it.

Thesis Statement: College athletes should be financially compensated because they sacrifice their minds and bodies, cannot hold an outside job, and increase the school’s revenue.

Support Paragraph 1 Topic Sentence: Student athletes should be paid for their performance because of sports’ impact on their minds and bodies.

Support Paragraph 2 Topic Sentence: Because most college athletes cannot play their sport and hold a job, colleges should give them a living wage.

Support Paragraph 3 Topic Sentence: Student-athletes’ ability to increase their college’s revenue proves they should be awarded financial compensation.

Thesis Statement: Using alternative energy sources can help lessen the impact of global climate change.

Support Paragraph 1 Topic Sentence: Through the widespread use of solar power, countries can limit the environmental impact of other energy sources.

Support Paragraph 2 Topic Sentence: Utilizing more wind turbines as a power source can help mitigate the effects of climate change.

Support Paragraph 3 Topic Sentence: Using geothermal power will effectively decrease the world's reliance on fossil fuels.

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Paragraphs: Topic Sentences

• Academic Paragraphs: Introduction to Paragraphs and the MEAL Plan (video transcript)
• Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

What is a Topic Sentence? (Definition, Examples, How to Use)

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

• Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
• Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
• If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

Topic Sentences

Pick up any newspaper or magazine and read the first sentence of an article. Are you fairly confident that you know what the rest of the article is about? If so, you have likely read the topic sentence. An effective topic sentence combines a subject with the writer’s position on that subject or claim about it. It serves to orient the reader and provides an indication of what will follow in the rest of the paragraph. Example:

This topic sentence declares a position in favor of standardizing math and English education. After reading this sentence, a reader might reasonably expect the writer to provide supporting details and facts as to why standardizing math and English education might improve student learning in many states. If the purpose of the essay is actually to evaluate education in only one particular state, or to discuss math or English education specifically, then the topic sentence is misleading and should be revised to say so.

Subject Versus Claim

Good topic sentences contain both a subject (the overall matter, issue, or field of inquiry) and a claim (the writer’s specific point about the subject, or position on it). Different writers may use the same subject but can steer their paragraph in a number of different directions according to their claim, or stance on the subject. Examples:

• Marijuana is a destructive influence on teens and causes long-term brain damage.
• The anti-nausea properties in marijuana are a lifeline for many cancer patients.
• Legalizing marijuana would create a higher demand for Class A and Class B drugs.

Although the subject—marijuana—is the same in all three topic sentences, the claim differs depending on the writer’s viewpoint. For instance, in the first sentence, the claim about marijuana is that it “is a destructive influence on teens and causes long-term brain damage.”

Separately identify the subject and the claim about it in each of the following topic sentences:

1. Exercising three times a week is the only way to maintain good physical health.

2. Sexism and racism are still rampant in today’s workplace.

3. Raising the legal driving age to twenty-one would decrease road traffic accidents.

4. Owning a business is the only way to achieve financial success.

5. Dog owners should be prohibited from taking their pets on public beaches.

Characteristics of a Good Topic Sentence

The following are characteristics good topic sentences:

• A good topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak example. People rarely give firefighters the credit they deserve for such a physically and emotionally demanding job. (The paragraph is about a specific incident that involved firefighters; therefore, this topic sentence is too general.)

Stronger example. During the October riots, Unit 3B went beyond the call of duty. (This topic sentence is more specific and indicates that the paragraph will contain information about a particular incident involving Unit 3B.)

• A good topic sentence contains both a subject and claim.

Weak example. In this paper, I am going to discuss the rising suicide rate among young professionals. (This topic sentence provides a subject, but it does not present a claim.)

Stronger example. The rising suicide rate among young professionals should become a higher priority among the concerns of human resource departments. (This topic sentence presents the writer’s claim on the subject of rising suicide rates among young professionals.)

• A good topic sentence is clear and easy to follow.

Weak example. In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types. (This topic sentence includes a subject and claim, but both are buried beneath the confusing sentence structure and unnecessary vocabulary. These obstacles make it difficult for the reader to follow.)

Stronger example. Most forms of writing can be improved by first creating an outline. (This topic sentence cuts out unnecessary words and simplifies the previous statement, making it easier for the reader to follow.)

• A good topic sentence does not include supporting details.

Weak example. Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the teams with budgets that exceed their competitors by four or five times to have such an extreme advantage year after year. (This topic sentence includes a supporting detail that should be included later in the paragraph to support the main point.)

Stronger example. Introducing a salary cap would improve the game of baseball for many reasons. (This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph.)

Choose the most effective topic sentence from the following sentence pairs.

1. Which is the more effective topic sentence?

a. This paper will discuss the likelihood of the Democrats winning the next election.

b. To boost their chances of winning the next election, the Democrats need to listen to public opinion.

2. Which is the more effective topic sentence?

a. The unrealistic demands of union workers are crippling the economy for the following three reasons.

b. Union workers are crippling the economy because companies are unable to remain competitive as a result of added financial pressure, which in turn forces companies trying to survive to relocate overseas where non-union wages can be half or in some cases less than half of union wages.

3. Which is the more effective topic sentence?

a. Major companies are stealing back digital content that customers purchased, which is destroying the very concept of ownership.

b. Technology is having drastic effects on how companies deal with digital sales nowadays.

4. Which is the more effective topic sentence?

a. Pop music has lost the genuine heart and superb artistry that it displayed in the past.

b. This essay will consider the quality of pop music.

Using the tips on developing effective topic sentences in this section, create a topic sentence on each of the following subjects. Remember to include the subject as well as the claim.

An endangered species

Topic Sentences

Topic sentence definition.

Like the thesis, topic sentences themselves have topics and angles. The topic may be the same as the thesis’ topic, but the angle differs depending on the part of the thesis angle the topic sentence is offering. Think of topic sentences in this way: The thesis sentence offers the main idea or insight for the whole essay; a topic sentence offers the main idea or insight for a section of the essay. To use another metaphor, a thesis sentence illuminates the whole space; a topic sentence illuminates one portion of the space.

Thesis Sentence

Topic Sentence

Here’s an example

Thesis sentence :   Trends in home lighting change as aesthetic values respond to social experience; this is most noticeable if you compare lighting trends of the 1960s, 1990s, and today.

Topic Sentence : Lighting in the 1960s was ebullient, in-your-face lighting, with big glass globes and colorful “mod” desk lamps, characterizing both the optimism and rebellion of the decade.

Topic Sentence :   1990s lighting trends focused on both technology, reflecting the new importance of technical advances during that decade, and ornate metallic accents, reflecting wealth and stability, as seen in the trends for track lighting and brass lamps and chandeliers.

Topic Sentence : Today’s lighting trends focus on cleaner lines and softer metallics, characterizing a need for simplicity and calm in an increasingly complex and anxious world.

For example, consider the following topic sentence and supporting paragraph from an essay whose thesis deals (humorously) with ways in which fast-food chains make profits.

Thesis :   Fun can be all-consuming, and we’re fond of consuming “fun.”  Fast-food chains are known for clowning around, adding a dollop for a dollar, including special “forget sauce” in their meals, and playing games with portions, all of which create profits as hefty as our waistlines may become.

Topic sentence and supporting paragraph :

Many fast-food chains make their profits from adding a special ingredient called “forget sauce” to their foods. ( This topic sentence extracts one of the ideas from the thesis.  It also controls the paragraph that follows, so that all sentences in the paragraph or unit of support must relate in some way to fast food, profit, and “forget sauce.”) Made largely from edible oil products, this condiment is never listed on the menu. ( This sentence fits in with the topic sentence because it is a description of the composition of “forget sauce.” ) In addition, this well-kept industry secret is the reason why ingredients are never listed on the packaging of victuals sold by these restaurants. ( The transitional phrase “In addition” relates the composition of “forget sauce” to secret fast-food industry practices. ) “Forget sauce” has a chemical property which causes temporary amnesia in consumers. ( This sentence states the short-term effect on consumers. ) After spending too much money on barely edible food bereft of any nutritional value, most consumers swear they will never repeat such a disagreeable experience. Within a short period, however, the chemical in “forget sauce” takes effect, and they can be depended upon to return and spend, older but no wiser. ( This sentence describes its longer-term effects and relates back to the thesis sentence, as it discusses profits made from “forget sauce.”)

The following brief video provides a simple way of explaining an important concept about topic sentences, that they link supporting ideas and examples to the thesis throughout an essay and create a logical flow of ideas within an essay.

V. Process and Organization

5.3 Writing Paragraphs

Kathryn Crowther; Lauren Curtright; Nancy Gilbert; Barbara Hall; Tracienne Ravita; Kirk Swenson; Terri Pantuso; and Kalani Pattison

Once you decide on a method for organizing your essay, you’ll want to start drafting your paragraphs. Think of your paragraphs as links in a chain where coherence and continuity are key. Imagine reading one long block of text, with each idea blurring into the next. You are likely to lose interest in a piece of writing that is disorganized and spans many pages without breaks. Paragraphs separate ideas into logical, manageable chunks, each paragraph focusing on only one main idea and presenting coherent sentences to support that one point. Because all the sentences in one paragraph support the same point, a paragraph may stand on its own. For most types of informative or persuasive academic writing, writers find it helpful to think of the paragraph analogous to an essay, as each is controlled by a main idea or point, and that idea is developed by an organized group of more specific ideas. Thus, the thesis of the essay is analogous to the topic sentence of a paragraph, just as the supporting sentences in a paragraph are analogous to the supporting paragraphs in an essay.

In essays, each supporting paragraph adds another related main idea to support the writer’s thesis, or controlling idea. Each related supporting idea is developed with facts, examples, and other details that explain it. By exploring and refining one idea at a time, writers build a strong case for their thesis. Effective paragraphing makes the difference between a satisfying essay that readers can easily process and one that requires readers to mentally organize the piece themselves. Thoughtful organization and development of each body paragraph leads to an effectively focused, developed, and coherent essay.

An effective paragraph contains three main parts:

• a topic sentence
• body, supporting sentences
• a concluding sentence

In informative and persuasive writing, the topic sentence is usually the first or second sentence of a paragraph and expresses its main idea, followed by supporting sentences that help explain, prove, or enhance the topic sentence. In narrative and descriptive paragraphs, however, topic sentences may be implied rather than explicitly stated, with all supporting sentences working to create the main idea. If the paragraph contains a concluding sentence, it is the last sentence in the paragraph and reminds the reader of the main point by restating it in different words.

Creating Focused Paragraphs with Topic Sentences

The foundation of a paragraph is the topic sentence which expresses the main idea or point of the paragraph. A topic sentence functions in two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information such as facts, details, or examples.

An effective topic sentence has the following characteristics:

• A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak Example

First, we need a better way to educate students.

Explanation: The claim is vague because it does not provide enough information about what will follow and it is too broad to be covered effectively in one paragraph.

Stronger Example

Creating a national set of standards for math and English education will improve student learning in many states.

Explanation: The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.

• A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year.

Explanation: This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.

Introducing a salary cap would improve the game of baseball for many reasons.

Explanation: This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.

• A good topic sentence is clear and easy to follow.

In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types.

Explanation: The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.

Most forms of writing can be improved by first creating an outline.

Explanation: This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

Location of Topic Sentences

As previously discussed, a topic sentence can appear anywhere within a paragraph depending upon the mode of writing, or it can be implied such as in narrative or descriptive writing. In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects. The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After seeing an ad for a new ABC show on Hulu this week I wondered why we are still being bombarded with reality shows on multiple platforms. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. The Golden Bachelor features a 71 year old bachelor and his 65-and-older potential romantic partners. A promo for the first episode highlights stereotypical generational differences between the main love interest and usual “bachelors,” emphasizing the show’s attempt at uniqueness. For instance, the promo claims, “his DMs have postage,” and “if you call him, he’ll answer the phone.” [1] Articles about the show seem to continually mention the purported demand for this spinoff and the producers’ need for the “right” bachelor. I dread to think what producers will come up with in future years and hope that other viewers will express their criticism of yet more false romances leading to unhealthy relationships. These producers must stop the constant stream of meaningless shows without plotlines. We’ve had enough reality television to last us a lifetime.

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded . Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show The Golden Bachelor ). Most academic essays contain the topic sentence at the beginning of the first paragraph. However, when utilizing a specific to general method, the topic sentence may be located later in the paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence, and the concluding sentence is the same as the topic sentence. This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

When the Topic Sentence Appears in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety. Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all, a technique often used in descriptive and narrative writing. Instead of being directly stated, the main idea is implied in the content of the paragraph, as in the following narrative paragraph.

Example of Implied Topic Sentence

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment, stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated so that all the details in the paragraph can work together to convey the dominant impression of Luella’s age. In a paragraph such as this one, an explicit topic sentence would seem awkward and heavy-handed. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Developing Paragraphs

If you think of a paragraph as a sandwich, the supporting sentences are the filling between the bread. They make up the body of the paragraph by explaining, proving, or enhancing the controlling idea in the topic sentence. The overall method of development for paragraphs depends upon the essay as a whole and the purpose of each paragraph; thus paragraphs may be developed by using examples, description, narration, comparison and contrast, definition, cause and effect, classification and division. A writer may use one method or combine several methods.

Writers often want to know how many words a paragraph should contain, and the answer is that a paragraph should develop the idea, point, or impression completely enough to satisfy the writer and readers. Depending on their function, paragraphs can vary in length from one or two sentences, to over a page; however, in most college assignments, successfully developed paragraphs usually contain approximately one hundred to two hundred and fifty words and span one-fourth to two-thirds of a typed page. A series of short paragraphs in an academic essay can seem choppy and unfocused, whereas paragraphs that are one page or longer can tire readers. Giving readers a paragraph break on each page helps them maintain focus.

This advice does not mean, of course, that composing a paragraph of a particular number of words or sentences guarantees an effective paragraph. Writers must provide enough supporting sentences within paragraphs to develop the topic sentence and simultaneously carry forward the essay’s main idea.

For example, in a descriptive paragraph about a room in the writer’s childhood home, a length of two or three sentences is unlikely to contain enough details to create a picture of the room in the reader’s mind, and it will not contribute in conveying the meaning of the place. In contrast, a half page paragraph, full of carefully selected vivid, specific details and comparisons, provides a fuller impression and engages the reader’s interest and imagination. In descriptive or narrative paragraphs, supporting sentences present details and actions in vivid, specific language in objective or subjective ways, appealing to the readers’ senses to make them see and experience the subject. In addition, some sentences writers use make comparisons that bring together or substitute the familiar with the unfamiliar, thus enhancing and adding depth to the description of the incident, place, person, or idea.

In a persuasive essay about raising the wage for certified nursing assistants, a paragraph might focus on the expectations and duties of the job, comparing them to that of a registered nurse. Needless to say, a few sentences that simply list the certified nurse’s duties will not give readers a complete enough idea of what these healthcare professionals do. If readers do not have plenty of information about the duties and the writer’s experience in performing them for what she considers inadequate pay, the paragraph fails to do its part in convincing readers that the pay is inadequate and should be increased.

In informative or persuasive writing, a supporting sentence usually offers one of the following:

• Reason:  The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.
• Fact: Many families now rely on older relatives to support them financially.
• Statistic: Nearly 10 percent of adults are currently unemployed in the United States.
• Quotation: “We will not allow this situation to continue,” stated Senator Johns.
• Example: Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing. For example, if you are attempting to persuade your audience to take a particular position, you should rely on facts, statistics, and concrete examples, rather than personal opinions. Personal testimony in the form of an extended example can be used in conjunction with the other types of support.

Consider the elements in the following paragraph.

Example Persuasive Paragraph

Topic sentence: There are numerous advantages to owning a hybrid car.

Sentence 1 (statistic): First, they get 20 percent to 35 percent more miles to the gallon than a fuel- efficient gas-powered vehicle.

Sentence 2 (fact): Second, they produce very few emissions during low speed city driving.

Sentence 3 (reason): Because they do not require as much gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump.

Sentence 4 (example): Alex bought a hybrid car two years ago and has been extremely impressed with its performance.

Sentence 5 (quotation): “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas powered vehicles I’ve owned.”

Concluding sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Sometimes the writing situation does not allow for research to add specific facts or other supporting information, but paragraphs can be developed easily with examples from the writer’s own experience.

Farheya, a student in a freshman English Composition class, quickly drafted an essay during a timed writing assignment in class. To practice improving paragraph development, she selected the body paragraph below to add support:

Example of Original Body Paragraph

Topic: Should parents prevent their children from watching television? Discuss.

Preventing children from watching television is  a way for parents to preserve their children’s innocence and keep exposure towards anything inappropriate at bay. From simply seeing movies and television when I was younger, I saw things I shouldn’t have, no matter how fast I switched the channel. Television shows and movies not only display physical indecency, but also verbal. Movies on TV sometimes do voice-overs of profane words, but they also leave a few words uncensored. The ease of flipping through channels on cable or choosing a show on a streaming service based on misleading descriptors or images, makes TV potentially toxic for the minds of children, and if parents prevented TV in general, they wouldn’t have to worry about what their children may accidentally see or hear.

The original paragraph identifies two categories of indecent material, and there is mention of profanity to provide a clue as to what the student thinks is indecent. However, the paragraph could use some examples to make the idea of inappropriate material clearer. Farheya considered some of the television shows she had seen and made a few changes.

Example of Revised Body Paragraph

Preventing children from watching television is  a way for parents to preserve their children’s innocence and keep exposure towards anything inappropriate at bay. From simply seeing movies and television when I was younger, I saw things I shouldn’t have, no matter how fast I switched the channel. For instance, Game of Thrones quickly became known for its graphic violence and sexuality, but the widespread viewership of the series made it pervasively part of popular culture. Fans of other fantasy media, such as Peter Jackson’s Lord of the Rings , were pulled into the cinematography and world-building, and as it was “fantasy,” parents may not have realized the inappropriateness of the contents and let their children watch it, especially if the children were fans of fantasy and the parents were not interested in the genre. Television shows not only display physical indecency, but also verbal. Many television shows have no filters, and the characters say profane words freely. South Park , as a cartoon, seems as if it may be relatively safe to pass by and may be mostly relatively visually innocent, but the continual profanity, frequent discussions implying the fourth-grade main characters are sexually active, and the demeaning language concerning a wide range of people and groups. Though the show started in 1997, it is still running today and original episodes and re-runs make it a frequent encounter on cable tv as well as various streaming services at different times.   The ease of flipping through channels on cable or choosing a show on a streaming service based on misleading descriptors or images, makes TV potentially toxic for the minds of children, and if parents prevented TV in general, they wouldn’t have to worry about what their children may accidentally see or hear.

Farheya’s addition of a few examples helps to convey why she thinks she would be better off without a television. Depending on the context of the paragraph and its centrality to a larger argument, she could even add more specifics for further persuasive evidence. She might decide to add specific descriptions of scenes (such as a description of the violence or sexual content in Game of Thrones ) or quotations (demonstrating the discussed profanity or sexual content in South Park ) from the relevant shows.

Concluding Sentences

An effective concluding sentence draws together all the ideas raised in your paragraph. It reminds readers of the main point—the topic sentence—without restating it in exactly the same words. Using the hamburger example, the top bun (the topic sentence) and the bottom bun (the concluding sentence) are very similar. They frame the “meat” or body of the paragraph.

Compare the topic sentence and concluding sentence from the first example on hybrid cars:

Topic Sentence: There are many advantages to owning a hybrid car.

Concluding Sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Notice the use of the synonyms advantages and benefits . The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

Writers should avoid introducing any new ideas into a concluding sentence because a conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse readers and weaken the writing.

A concluding sentence may do any of the following:

• Restate the main idea.

Childhood obesity is a growing problem in the United States.

• Summarize the key points in the paragraph

A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

• Draw a conclusion based on the information in the paragraph.

These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

• Make a prediction, suggestion, or recommendation about the information in the paragraph.

Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

• Offer an additional observation about the controlling idea.

Childhood obesity is an entirely preventable tragedy.

Paragraph Length

Although paragraph length is discussed in the section on developing paragraphs with supporting sentences, some additional reminders about when to start a new paragraph may prove helpful to writers:

• If a paragraph is over a page long, consider providing a paragraph break for readers. Look for a logical place to divide the paragraph; then revise the opening sentence of the second paragraph to maintain coherence.
• A series of short paragraphs can be confusing and choppy. Examine the content of the paragraphs and combine ones with related ideas or develop each one further.
• When dialogue is used, begin a new paragraph each time the speaker changes.
• Begin a new paragraph to indicate a shift in subject, tone, or time and place.

Improving Paragraph Coherence

A strong paragraph holds together well, flowing seamlessly from the topic sentence into the supporting sentences and on to the concluding sentence. To help organize a paragraph and ensure that ideas logically connect to one another, writers use a combination of elements:

• A clear organizational pattern: chronological (for narrative writing and describing processes), spatial (for descriptions of people or places), order of importance, general to specific (deductive), specific to general (inductive)
• Transitional words and phrases: These connecting words describe a relationship between ideas.
• Repetition of ideas: This element helps keep the parts of the paragraph together by maintaining focus on the main idea, so this element reinforces both paragraph coherence and unity.

In the following example, notice the use of transitions ( bolded ) and key words ( underlined ):

Example of Transition Words

Owning a hybrid car benefits both the owner and the environment . First , these cars get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. Second , they produce very few emissions during low speed city driving. Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. Alex bought a hybrid car two years ago and has been extremely impressed with its performance. “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas-powered vehicles I’ve owned.” Given the low running costs and environmental benefits of owning a hybrid car , it is likely that many more people will follow Alex’s example in the near future.

Words such as first and second are transition words that show sequence or clarify order. They help organize the writer’s ideas by showing that he or she has another point to make in support of the topic sentence. The transition word because is a transition word of consequence that continues a line of thought. It indicates that the writer will provide an explanation of a result. In this sentence, the writer explains why hybrid cars will reduce dependency on fossil fuels (because they do not require gas).

In addition to transition words, the writer repeats the word hybrid (and other references such as these cars , and they ), and ideas related to benefits to keep the paragraph focused on the topic and hold it together.

To include a summarizing transition for the concluding sentence, the writer could rewrite the final sentence as follows:

In conclusion, given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Although the phrase “in conclusion” certainly reinforces the idea of summary and closure, it is not necessary in this case and seems redundant, as the sentence without the phrase already repeats and summarizes the benefits presented in the topic sentence and flows smoothly from the preceding quotation. The second half of the sentence, in making a prediction about the future, signals a conclusion, also making the phrase “in conclusion” unnecessary. The original version of the concluding sentence also illustrates how varying sentence openings can improve paragraph coherence. As writers continue to practice and develop their style, they more easily make these decisions between using standard transitional phrases and combining the repetition of key ideas with varied sentence openings.

Table 5.3.1 provides some useful transition words and phrases to connect sentences within paragraphs as well as to connect body paragraphs:

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

Topic Sentence: Crafting Impactful Introductions

By: Author Paul Jenkins

Posted on October 9, 2023

Categories Education , Writing

Topic sentences play a crucial role in structuring and organizing any piece of writing. Serving as the foundation for each paragraph, they act as a guide for both the writer and the reader to know the main ideas being discussed. A well-crafted topic sentence provides clarity and focus, helping to ensure that the content is coherent, engaging, and easily understood.

Writing an effective topic sentence requires careful consideration of the paragraph’s purpose and the overall structure of the essay. By presenting the topic with precision and using suitable transitions, your writing will flow smoothly and maintain a logical progression of ideas. Furthermore, incorporating supportive evidence and examples will strengthen the credibility and persuasiveness of your argument.

Key Takeaways

• Topic sentences set the foundation for each paragraph, organizing and clarifying the main ideas.
• Effective topic sentences require careful consideration of the paragraph’s purpose, transitions, and supporting evidence.
• Crafting strong topic sentences enhances the overall coherence, engagement, and persuasiveness of your writing.

Understanding Topic Sentences

When you write a paragraph, an essential element is the topic sentence . It serves as the backbone of the paragraph by expressing its main idea. A well-constructed topic sentence helps the reader understand the purpose and direction of your paragraph, making it easier to follow your thoughts.

As you embark on the writing process, remember that the topic sentence is responsible for conveying the main idea of a paragraph. It offers a roadmap for your readers, guiding them through your argument or explanation. In most cases, the topic sentence appears at the beginning of the paragraph, but it can also be located in the middle or the end. By positioning it strategically, you ensure that your readers can quickly grasp the content’s purpose.

There are several aspects to consider when crafting a topic sentence. First, it must be concise and specific enough to showcase the main idea without delving into unnecessary details. Additionally, it should be connected to your thesis statement, supporting the overall argument of your paper.

Consider the following tips for writing effective topic sentences:

• Begin with a clear and focused idea.
• Ensure that it is directly related to your thesis statement.
• Use strong, active verbs to convey your point.

Using these guidelines, you can confidently create topic sentences that effectively communicate your main ideas and improve the readability of your writing. Remember, clarity and conciseness are vital for having your readers comprehend the important points you aim to convey.

Elements of an Effective Topic Sentence

An effective topic sentence should be clear and concise. This means you should choose your words carefully and avoid using complex jargon or confusing phrases. Write in a way that your reader can quickly grasp the main point of the paragraph. By ensuring your topic sentence is clear, you help your reader better understand your argument.

Specificity

In addition to being clear, a strong topic sentence should be specific. This means that it clearly states the main idea of the paragraph and, when possible, includes key details. Avoid making broad, vague statements that leave the reader guessing what the paragraph will discuss. Instead, provide sufficient information to guide the reader through your argument. For example, instead of saying “There are many benefits to exercise,” a specific topic sentence would be “Regular exercise improves mental well-being, increases energy levels, and reduces the risk of chronic diseases.”

Relevance to Thesis

Finally, it is crucial that your topic sentence relates directly to your thesis statement. Each topic sentence should support the main argument you are trying to make in your paper. Ensure that every paragraph connects to your thesis and contributes to the overall message of your piece. This helps maintain coherence and unity in your writing, making it easier for readers to follow your thoughts and understand your perspective.

Remember, an effective topic sentence is one that is clear, specific, and relevant to your thesis statement. By focusing on these three elements, you can create strong paragraphs that support your argument and engage your readers.

The Role of Topic Sentences in Essay Structure

Introduction

The topic sentence plays a critical role in essay structure as it introduces the main idea of a paragraph. It helps you, the reader, to understand the key points of each section and serves as a roadmap for the entire essay. A strong topic sentence not only outlines the purpose of the paragraph, but it also sets the tone and helps maintain the flow of ideas throughout the essay.

Body of the Essay

In the body of your essay, each paragraph should feature a topic sentence that communicates the primary idea or argument of that section. This allows you, the reader, to follow your train of thought easily, ensuring a clear and coherent essay structure. The supporting details and evidence in each paragraph must also relate directly back to the topic sentence, enabling a logical, well-organized essay that is both engaging and informative.

Here are some points to consider when crafting topic sentences for the body of your essay:

• Keep the topic sentence concise and specific
• Ensure it encapsulates the main idea or argument of the paragraph
• Make sure it serves as a smooth transition from the previous paragraph

Summary and Conclusion

Although the summary and conclusion section of your essay does not require a topic sentence in the traditional sense, you still need to introduce and restate the main points made throughout your essay. This section should also provide insight on the implications of your argument and leave the reader with a lasting impression. Remember, clarity and conciseness are key elements in conveying your ideas effectively.

In summary, topic sentences are crucial for establishing a strong essay structure. By paying close attention to your introduction, body paragraphs, and summary or conclusion, you (as the writer) can create a cohesive and engaging argument that will hold your reader’s attention from start to finish.

The Power of Transitions in Writing

Transitions play a crucial role in maintaining the flow of your writing. They act as connective tissue, linking ideas and ensuring a smooth journey for your readers. By incorporating transition words and phrases, you can guide your readers through your arguments and enhance the clarity of your work.

To create seamless connections between your ideas, it’s essential to use transition sentences. These sentences establish relationships between different parts of your text and provide a bridge for your readers. For example, if you discuss one point and want to introduce a contrasting idea, you might use a transition like “however” or “on the other hand.” This helps your reader understand the shift in focus and maintains the flow of your writing.

Another aspect of transitioning involves structuring your content effectively. By organizing your ideas into paragraphs and sections, you establish a roadmap for your readers. This organization allows your readers to follow your thought process, making your writing more clear and coherent . Additionally, using headings and subheadings can provide easy reference points and make your work more reader-friendly.

When choosing the right transition words and phrases, be mindful of the tone you want to convey. Opt for transitions that match the level of formality appropriate for your context. For example, informal writing might use phrases like “on top of that” or “next up,” while formal writing might prefer “additionally” or “subsequently.”

Try incorporating these different types of transitions in your writing:

• Additive transitions: They introduce additional information or ideas, e.g., “furthermore,” “moreover,” “in addition.”
• Adversative transitions: They signal conflict, disagreement, or contrast, e.g., “however,” “on the contrary,” “nevertheless.”
• Causal transitions: They show cause and effect relationships, e.g., “therefore,” “as a result,” “consequently.”
• Sequential transitions: They indicate a sequence or chronology, e.g., “first,” “next,” “initially.”

By mastering the power of transitions, you can elevate your writing, making it not only more engaging but also easier to understand. Keep practicing and experimenting with different transition words and phrases to discover which ones work best for your style and the specific writing project at hand.

Crafting Topic Sentences: A Guide

Choosing the Right Tone

When crafting a topic sentence, it’s important to choose the right tone. Aim for a confident, knowledgeable, neutral, and clear tone of voice in order to effectively convey your ideas. Start by focusing on the main point of your paragraph and make sure the topic sentence reflects that idea. As a result, your reader will have a better understanding of what to expect in the upcoming paragraph.

Utilizing Effective Phrasing

The phrasing of your topic sentence plays a crucial role in the overall structure of your paragraph. Consider these tips to improve your phrasing:

• Be concise: Avoid using unnecessary words or phrases that may confuse your reader.
• Keep it clear: Focus on using simple and straightforward language so your reader can easily understand your point.
• Be specific: Make sure the focus of your topic sentence is directly related to the content of the paragraph.

By utilizing effective phrasing, you’ll ensure that your topic sentence serves as an accurate guide for your reader.

Placement Strategy

The placement of your topic sentence is just as important as its content. Typically, a topic sentence should be placed at the beginning of a paragraph. This allows the reader to immediately understand the main idea of the paragraph. However, occasionally, you may experiment with placing the topic sentence in the middle or at the end of the paragraph for added emphasis or variation.

But regardless of your placement strategy, remember to maintain a clear and consistent structure throughout your writing. This will make it easier for your reader to follow your train of thought and stay engaged with the content.

By following this guide to crafting topic sentences, you’ll be better equipped to create well-structured, effective paragraphs that clearly communicate your ideas to your reader.

Importance of Evidence in Topic Sentences

In your writing, providing evidence in topic sentences is essential to supporting your argument. Strong evidence demonstrates your knowledge of the subject matter and helps the reader understand your point of view.

Consider using data as the backbone of your topic sentence. Presenting factual data gives your arguments a robust foundation and adds credibility to your writing. For example, you could begin a paragraph with the following topic sentence: “Recent studies show that physical exercise reduces the risk of depression by 30%.” By providing a precise percentage, you establish a solid base for further discussion.

In addition to data, your analysis of the subject matter is crucial. Demonstrating your ability to dissect complex information and derive meaningful conclusions from it adds depth to your argument. After presenting data in your topic sentence, devote the rest of the paragraph to interpreting this data and its implications. This approach shows your commitment to understanding the topic and helps the reader appreciate your thought process.

Remember that evidence must be relevant and reliable. Ensure that the sources of your evidence are credible and up-to-date. For instance, instead of relying on anecdotal evidence, cite published research studies, reputable news articles, or official statistics.

In summary, emphasizing evidence in your topic sentences strengthens your writing by increasing its credibility and substance. By incorporating data, analysis, and reliable sources, you create a persuasive and engaging piece that effectively communicates your message to the reader.

Exploring Examples of Topic Sentences

As a writer, it’s essential to understand the importance of topic sentences in crafting compelling paragraphs. These sentences serve as a guide for your readers, outlining the main idea you will explore in each paragraph. Let’s dive into some examples of topic sentences, so you can gain confidence in writing your own.

When constructing a narrative piece, your topic sentence should establish a clear direction for the paragraph. For example:

• You were barely awake, and your senses were foggy as you stumbled out of bed.

In this example, the topic sentence quickly sets the scene and orients readers to the character’s feelings and environment. From here, your paragraph can explore details about the character’s morning routine or the events that follow.

An argumentative essay requires topic sentences that clearly state your position and support your thesis. Consider the following example:

• Cell phones in the classroom can be beneficial if used as a tool for learning.

This topic sentence sets the focus on the pros of using cell phones for educational purposes. Your paragraph would then highlight specific examples and supporting evidence that back up this claim.

When comparing and contrasting, your topic sentences should highlight a specific aspect of the subjects being examined. Consider this example:

• Though both apples and oranges are fruits, they have distinctly different tastes that appeal to different palates.

Here, the topic sentence emphasizes the contrast between apples and oranges regarding taste. Your paragraph would then elaborate on the flavor profiles of each fruit and how they differ.

In an expository essay, your topic sentences should communicate the main point of each paragraph, like in the following example:

• Volunteering at a local animal shelter provides emotional benefits as well as the opportunity to make a meaningful impact on your community.

This topic sentence introduces the dual advantages of volunteering at an animal shelter. The paragraph that follows would delve into the specific emotional benefits and community impact that arises from such service.

By using confident, knowledgeable, and clear language, while keeping a neutral tone, you can effectively craft topic sentences for various types of writing. Whether you’re telling a story or making an argument, remember to focus on the main idea and set the stage for an engaging and informative paragraph.

The Role of the Reader and Audience

When crafting a topic sentence, it’s crucial to consider the reader and audience, especially if you are writing for high school students. Engaging the audience sets the stage for a successful piece of writing. Here are a few points to keep in mind as you write with the reader and audience in mind:

Understand your audience : Consider the knowledge, needs, and interests of your reader. Is the high school audience familiar with the subject matter? What do they want to learn or gain from reading your work?

Adjust your tone : Adopt a confident, knowledgeable, neutral, and clear tone of voice. Your reader will feel that you understand the topic, and this will help to establish credibility.

Keep it concise : High school students prefer concise content as it’s easier to digest. Be straightforward and avoid unnecessary jargon or complex language. Breaking your content into paragraphs can also help with readability.

Engage the reader : Make your writing relevant and relatable to your target audience. Including vivid examples and anecdotes that resonate with high school students can help keep their interest.

Incorporate appropriate formatting : Utilize formatting techniques such as tables, bullet points, and bold text to emphasize important information. This will make your writing visually appealing and easier to navigate for your reader.

Remember, the main goal of a topic sentence is to engage the reader and introduce your paragraph’s topic. Keeping the needs and interests of your high school audience in mind will ensure that you create effective topic sentences that capture their attention and facilitate better understanding throughout your writing.

Conclusion: The Benefits of Strong Topic Sentences

A well-crafted topic sentence offers numerous benefits, ensuring your writing is clear and concise. By incorporating strong topic sentences, you can improve the focus of your paragraphs, making it easier for readers to follow your train of thought. They also aid in summarizing the main points of a section, streamlining your arguments and allowing for a better understanding of the content.

When you write a strong topic sentence, you guide the reader through your argument, efficiently communicating the purpose of each paragraph. This makes your writing coherent and straightforward, supporting the flow of ideas and allowing the reader to navigate your text with ease.

Furthermore, a focused topic sentence helps you, the writer, maintain a clear line of thought. By establishing a solid foundation for each paragraph, you ensure that your ideas remain on track and that the message you want to deliver is effectively communicated to your audience.

Remember that creating strong topic sentences should not be an afterthought. By prioritizing the development of concise and purposeful topic sentences, you’ll enhance the coherence and readability of your writing. This will lead to a more engaging and effective document, whether it’s an essay, research paper, or any other form of written work. So, don’t underestimate the power of a well-crafted topic sentence in elevating the overall quality of your writing.

Frequently Asked Questions

How to craft a strong topic sentence?

To craft a strong topic sentence, you should focus on expressing the main idea of a paragraph clearly and concisely. Make sure it is a complete sentence and relevant to the paragraph’s content. Furthermore, keep it engaging and informative to guide the readers throughout the paragraph.

What are some examples of effective topic sentences?

Some effective topic sentences include:

• “Technology has significantly transformed the way we communicate and connect with one another.”

How does a topic sentence differ from a thesis statement?

A topic sentence expresses the main point of a specific paragraph, providing focus and direction for the supporting details within that paragraph. A thesis statement, on the other hand, presents the central argument or claim of an entire essay and is usually found in the introduction. The thesis statement guides and informs all the paragraphs, while topic sentences connect individual paragraphs back to the central argument.

What are the key components of a topic sentence?

The key components of a topic sentence include:

• A clear and concise expression of the main idea or point.
• Relevance to the paragraph’s content.
• A smooth transition from the previous paragraph or idea (if applicable).
• Engaging and informative language.

These components help create a foundation for a well-structured and coherent paragraph.

How can a topic sentence enhance a paragraph’s coherence?

A topic sentence enhances a paragraph’s coherence by providing a clear focal point for the reader. It helps to organize the information and supporting details within the paragraph, ensuring that the content is logically connected and easy to understand. By setting the stage for the paragraph, a topic sentence effectively guides the reader through your ideas and arguments.

What techniques can be employed to create an engaging topic sentence?

To create an engaging topic sentence, try incorporating the following techniques:

• Use precise and compelling language.
• Ask a thought-provoking question.

6.2 Effective Means for Writing a Paragraph

Learning objectives.

• Identify characteristics of a good topic sentence.
• Identify the three parts of a developed paragraph.
• Apply knowledge of topic sentences and parts of a developed paragraph in an assignment.

Now that you have identified common purposes for writing and learned how to select appropriate content for a particular audience, you can think about the structure of a paragraph in greater detail. Composing an effective paragraph requires a method similar to building a house. You may have the finest content, or materials, but if you do not arrange them in the correct order, then the final product will not hold together very well.

A strong paragraph contains three distinct components:

• Topic sentence . The topic sentence is the main idea of the paragraph.
• Body . The body is composed of the supporting sentences that develop the main point.
• Conclusion . The conclusion is the final sentence that summarizes the main point.

The foundation of a good paragraph is the topic sentence, which expresses the main idea of the paragraph. The topic sentence relates to the thesis, or main point, of the essay (see Chapter 9 “Writing Essays: From Start to Finish” for more information about thesis statements) and guides the reader by signposting what the paragraph is about. All the sentences in the rest of the paragraph should relate to the topic sentence.

This section covers the major components of a paragraph and examines how to develop an effective topic sentence.

Developing a Topic Sentence

Pick up any newspaper or magazine and read the first sentence of an article. Are you fairly confident that you know what the rest of the article is about? If so, you have likely read the topic sentence. An effective topic sentence combines a main idea with the writer’s personal attitude or opinion. It serves to orient the reader and provides an indication of what will follow in the rest of the paragraph. Read the following example.

Creating a national set of standards for math and English education will improve student learning in many states.

This topic sentence declares a favorable position for standardizing math and English education. After reading this sentence, a reader might reasonably expect the writer to provide supporting details and facts as to why standardizing math and English education might improve student learning in many states. If the purpose of the essay is actually to evaluate education in only one particular state, or to discuss math or English education specifically, then the topic sentence is misleading.

When writing a draft of an essay, allow a friend or colleague to read the opening line of your first paragraph. Ask your reader to predict what your paper will be about. If he or she is unable to guess your topic accurately, you should consider revising your topic sentence so that it clearly defines your purpose in writing.

Main Idea versus Controlling Idea

Topic sentences contain both a main idea (the subject, or topic that the writer is discussing) and a controlling idea (the writer’s specific stance on that subject). Just as a thesis statement includes an idea that controls a document’s focus (as you will read about in Chapter 8 “The Writing Process: How Do I Begin?” ), a topic sentence must also contain a controlling idea to direct the paragraph. Different writers may use the same main idea but can steer their paragraph in a number of different directions according to their stance on the subject. Read the following examples.

• Marijuana is a destructive influence on teens and causes long-term brain damage.
• The antinausea properties in marijuana are a lifeline for many cancer patients.
• Legalizing marijuana would create a higher demand for Class A and Class B drugs.

Although the main idea—marijuana—is the same in all three topic sentences, the controlling idea differs depending on the writer’s viewpoint.

Circle the main idea and underline the controlling idea in each of the following topic sentences.

• Exercising three times a week is the only way to maintain good physical health.
• Sexism and racism are still rampant in today’s workplace.
• Raising the legal driving age to twenty-one would decrease road traffic accidents.
• Owning a business is the only way to achieve financial success.
• Dog owners should be prohibited from taking their pets on public beaches.

Characteristics of a Good Topic Sentence

Five characteristics define a good topic sentence:

A good topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak example. People rarely give firefighters the credit they deserve for such a physically and emotionally demanding job. (The paragraph is about a specific incident that involved firefighters; therefore, this topic sentence is too general.)

Stronger example. During the October riots, Unit 3B went beyond the call of duty. (This topic sentence is more specific and indicates that the paragraph will contain information about a particular incident involving Unit 3B.)

A good topic sentence contains both a topic and a controlling idea or opinion.

Weak example. In this paper, I am going to discuss the rising suicide rate among young professionals. (This topic sentence provides a main idea, but it does not present a controlling idea, or thesis.)

Stronger example. The rising suicide rate among young professionals is a cause for immediate concern. (This topic sentence presents the writer’s opinion on the subject of rising suicide rates among young professionals.)

A good topic sentence is clear and easy to follow.

Weak example. In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types. (This topic sentence includes a main idea and a controlling thesis, but both are buried beneath the confusing sentence structure and unnecessary vocabulary. These obstacles make it difficult for the reader to follow.)

Stronger example. Most forms of writing can be improved by first creating an outline. (This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow.)

A good topic sentence does not include supporting details.

Weak example. Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year. (This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.)

Stronger example. Introducing a salary cap would improve the game of baseball for many reasons. (This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph.)

A good topic sentence engages the reader by using interesting vocabulary.

Weak example. The military deserves better equipment. (This topic sentence includes a main idea and a controlling thesis, but the language is bland and unexciting.)

Stronger example. The appalling lack of resources provided to the military is outrageous and requires our immediate attention. (This topic sentence reiterates the same idea and controlling thesis, but adjectives such as appalling and immediate better engage the reader. These words also indicate the writer’s tone.)

Choose the most effective topic sentence from the following sentence pairs.

Writing at Work

When creating a workplace document, use the “top-down” approach—keep the topic sentence at the beginning of each paragraph so that readers immediately understand the gist of the message. This method saves busy colleagues precious time and effort trying to figure out the main points and relevant details.

Headings are another helpful tool. In a text-heavy document, break up each paragraph with individual headings. These serve as useful navigation aids, enabling colleagues to skim through the document and locate paragraphs that are relevant to them.

Developing Paragraphs That Use Topic Sentences, Supporting Ideas, and Transitions Effectively

Learning how to develop a good topic sentence is the first step toward writing a solid paragraph. Once you have composed your topic sentence, you have a guideline for the rest of the paragraph. To complete the paragraph, a writer must support the topic sentence with additional information and summarize the main point with a concluding sentence.

This section identifies the three major structural parts of a paragraph and covers how to develop a paragraph using transitional words and phrases.

Identifying Parts of a Paragraph

An effective paragraph contains three main parts: a topic sentence, the body, and the concluding sentence. A topic sentence is often the first sentence of a paragraph. This chapter has already discussed its purpose—to express a main idea combined with the writer’s attitude about the subject. The body of the paragraph usually follows, containing supporting details. Supporting sentences help explain, prove, or enhance the topic sentence. The concluding sentence is the last sentence in the paragraph. It reminds the reader of the main point by restating it in different words.

Figure 6.2 Paragraph Structure Graphic Organizer

Read the following paragraph. The topic sentence is underlined for you.

After reading the new TV guide this week I had just one thought—why are we still being bombarded with reality shows? This season, the plague of reality television continues to darken our airwaves. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. Prisoner follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season, but if any of them are reading this blog—stop it! We’ve had enough reality television to last us a lifetime!

The first sentence of this paragraph is the topic sentence. It tells the reader that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded .

Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show Prisoner ). Most academic essays contain the topic sentence at the beginning of the first paragraph.

Now take a look at the following paragraph. The topic sentence is underlined for you.

Last year, a cat traveled 130 miles to reach its family, who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence and the concluding sentence is the same as the topic sentence.

This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

Sometimes, the topic sentence appears in the middle of a paragraph. Read the following example. The topic sentence is underlined for you.

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety.

Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic. To read more about topic sentences and where they appear in paragraphs, see Chapter 8 “The Writing Process: How Do I Begin?” .

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all. Instead of being directly stated, the main idea is implied in the content of the paragraph. Read the following example:

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment; stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated. This technique is often used in descriptive or narrative writing. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Avoid using implied topic sentences in an informational document. Readers often lose patience if they are unable to quickly grasp what the writer is trying to say. The clearest and most efficient way to communicate in an informational document is to position the topic sentence at the beginning of the paragraph.

Supporting Sentences

If you think of a paragraph as a hamburger, the supporting sentences are the meat inside the bun. They make up the body of the paragraph by explaining, proving, or enhancing the controlling idea in the topic sentence. Most paragraphs contain three to six supporting sentences depending on the audience and purpose for writing. A supporting sentence usually offers one of the following:

Sentence: The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.

Sentence: Many families now rely on older relatives to support them financially.

Sentence: Nearly 10 percent of adults are currently unemployed in the United States.

Sentence: “We will not allow this situation to continue,” stated Senator Johns.

Sentence: Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing. For example, if you are attempting to persuade your audience to take a particular position you should rely on facts, statistics, and concrete examples, rather than personal opinions. Read the following example:

There are numerous advantages to owning a hybrid car. (Topic sentence)

First, they get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. (Supporting sentence 1: statistic)

Second, they produce very few emissions during low speed city driving. (Supporting sentence 2: fact)

Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. (Supporting sentence 3: reason)

Alex bought a hybrid car two years ago and has been extremely impressed with its performance. (Supporting sentence 4: example)

“It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas powered vehicles I’ve owned.” (Supporting sentence 5: quotation)

Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future. (Concluding sentence)

To find information for your supporting sentences, you might consider using one of the following sources:

• Reference book
• Encyclopedia
• Biography/autobiography
• Newspaper/magazine
• Previous experience
• Personal research

To read more about sources and research, see Chapter 11 “Writing from Research: What Will I Learn?” .

When searching for information on the Internet, remember that some websites are more reliable than others. websites ending in .gov or .edu are generally more reliable than websites ending in .com or .org. Wikis and blogs are not reliable sources of information because they are subject to inaccuracies.

Concluding Sentences

An effective concluding sentence draws together all the ideas you have raised in your paragraph. It reminds readers of the main point—the topic sentence—without restating it in exactly the same words. Using the hamburger example, the top bun (the topic sentence) and the bottom bun (the concluding sentence) are very similar. They frame the “meat” or body of the paragraph. Compare the topic sentence and concluding sentence from the previous example:

Topic sentence: There are numerous advantages to owning a hybrid car.

Concluding sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Notice the use of the synonyms advantages and benefits . The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

You should avoid introducing any new ideas into your concluding sentence. A conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse the reader and weaken your writing.

A concluding sentence may do any of the following:

Restate the main idea.

Example: Childhood obesity is a growing problem in the United States.

Summarize the key points in the paragraph.

Example: A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

Draw a conclusion based on the information in the paragraph.

Example: These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

Make a prediction, suggestion, or recommendation about the information in the paragraph.

Example: Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

Offer an additional observation about the controlling idea.

Example: Childhood obesity is an entirely preventable tragedy.

On your own paper, write one example of each type of concluding sentence based on a topic of your choice.

Transitions

A strong paragraph moves seamlessly from the topic sentence into the supporting sentences and on to the concluding sentence. To help organize a paragraph and ensure that ideas logically connect to one another, writers use transitional words and phrases. A transition is a connecting word that describes a relationship between ideas. Take another look at the earlier example:

There are numerous advantages to owning a hybrid car. First , they get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. Second , they produce very few emissions during low speed city driving. Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. Alex bought a hybrid car two years ago and has been extremely impressed with its performance. “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas-powered vehicles I’ve owned.” Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Each of the underlined words is a transition word. Words such as first and second are transition words that show sequence or clarify order. They help organize the writer’s ideas by showing that he or she has another point to make in support of the topic sentence. Other transition words that show order include third , also , and furthermore .

The transition word because is a transition word of consequence that continues a line of thought. It indicates that the writer will provide an explanation of a result. In this sentence, the writer explains why hybrid cars will reduce dependency on fossil fuels (because they do not require gas). Other transition words of consequence include as a result , so that , since , or for this reason .

To include a summarizing transition in her concluding sentence, the writer could rewrite the final sentence as follows:

In conclusion, given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

The following chart provides some useful transition words to connect supporting sentences and concluding sentences. See Chapter 8 “The Writing Process: How Do I Begin?” for a more comprehensive look at transitional words and phrases.

Table 6.1 Useful Transitional Words and Phrases

Using your own paper, write a paragraph on a topic of your choice. Be sure to include a topic sentence, supporting sentences, and a concluding sentence and to use transitional words and phrases to link your ideas together.

Transitional words and phrases are useful tools to incorporate into workplace documents. They guide the reader through the document, clarifying relationships between sentences and paragraphs so that the reader understands why they have been written in that particular order.

For example, when writing an instructional memo, it may be helpful to consider the following transitional words and phrases: before you begin , first , next , then , finally , after you have completed . Using these transitions as a template to write your memo will provide readers with clear, logical instructions about a particular process and the order in which steps are supposed to be completed.

Key Takeaways

• A good paragraph contains three distinct components: a topic sentence, body, and concluding sentence.
• The topic sentence expresses the main idea of the paragraph combined with the writer’s attitude or opinion about the topic.
• Good topic sentences contain both a main idea and a controlling idea, are clear and easy to follow, use engaging vocabulary, and provide an accurate indication of what will follow in the rest of the paragraph.
• Topic sentences may be placed at the beginning, middle, or end of a paragraph. In most academic essays, the topic sentence is placed at the beginning of a paragraph.
• Supporting sentences help explain, prove, or enhance the topic sentence by offering facts, reasons, statistics, quotations, or examples.
• Concluding sentences summarize the key points in a paragraph and reiterate the main idea without repeating it word for word.
• Transitional words and phrases help organize ideas in a paragraph and show how these ideas relate to one another.

Imagine reading one long block of text, with each idea blurring into the next. You are likely to lose interest in a piece of writing that is disorganized and spans many pages without breaks. Paragraphs separate ideas into logical, manageable chunks, each paragraph focusing on only one main idea and presenting coherent sentences to support that one point. Because all the sentences in one paragraph support the same point, a paragraph may stand on its own. For most types of informative or persuasive academic writing, writers find it helpful to think of the paragraph analogous to an essay, as each is controlled by a main idea or point, and that idea is developed by an organized group of more specific ideas. Thus, the thesis of the essay is analogous to the topic sentence of a paragraph, just as the supporting sentences in a paragraph are analogous to the supporting paragraphs in an essay.

In essays, each supporting paragraph adds another related main idea to support the writer’s thesis, or controlling idea. Each related supporting idea is developed with facts, examples, and other details that explain it. By exploring and refining one idea at a time, writers build a strong case for their thesis. Effective paragraphing makes the difference between a satisfying essay that readers can easily process and one that requires readers to mentally organize the piece themselves. Thoughtful organization and development of each body paragraph leads to an effectively focused, developed, and coherent essay.

An effective paragraph contains three main parts:

• a topic sentence
• body, supporting sentences
• a concluding sentence

In informative and persuasive writing, the topic sentence is usually the first sentence or second sentence of a paragraph and expresses its main idea, followed by supporting sentences that help explain, prove, or enhance the topic sentence. In narrative and descriptive paragraphs, however, topic sentences may be implied rather than explicitly stated, with all supporting sentences working to create the main idea. If the paragraph contains a concluding sentence, it is the last sentence in the paragraph and reminds the reader of the main point by restating it in different words. The following figure illustrates the most common paragraph structure for informative and persuasive college essays.

The number of supporting sentences varies according to the paragraph’s purpose and the writer’s sentence structure.

Creating Focused Paragraphs with Topic Sentences

The foundation of a paragraph is the topic sentence, which expresses the main idea or point of the paragraph. The topic sentence functions two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information, such as facts, details, or examples.

An effective topic sentence has the following characteristics:

• Explanation : The claim is vague because it does not provide enough information about what will follow, and it is too broad to be covered effectively in one paragraph.
• Explanation : The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.
• Explanation : This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.
• Explanation : This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.
• Explanation : The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.
• Explanation : This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

Location of Topic Sentences

A topic sentence can appear anywhere within a paragraph or can be implied (such as in narrative or descriptive writing). In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects. The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After reading the new TV guide this week I wondered why we are still being bombarded with reality shows, a plague that continues to darken our airwaves . Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. Prisoner follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season and hope that other viewers will express their criticism. These producers must stop the constant stream of meaningless shows without plotlines. We’ve had enough reality television to last us a lifetime!

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded. Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show Prisoner ). Most academic essays contain the topic sentence at the beginning of the first paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family, who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence and the concluding sentence is the same as the topic sentence. This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

When the Topic Sentence Appears in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises . It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety. Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all, a technique often used in descriptive and narrative writing. Instead of being directly stated, the main idea is implied in the content of the paragraph, as in the following narrative paragraph:

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment, stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated so that all the details in the paragraph can work together to convey the dominant impression of Luella’s age. In a paragraph such as this one, an explicit topic sentence would seem awkward and heavy-handed. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.
