How to Write an Expository Essay | Structure, Tips & Examples

Published on July 14, 2020 by Jack Caulfield . Revised on July 23, 2023.

“Expository” means “intended to explain or describe something.” An expository essay provides a clear, focused explanation of a particular topic, process, or set of ideas. It doesn’t set out to prove a point, just to give a balanced view of its subject matter.

Expository essays are usually short assignments intended to test your composition skills or your understanding of a subject. They tend to involve less research and original arguments than argumentative essays .

In school and university, you might have to write expository essays as in-class exercises, exam questions, or coursework assignments.

Sometimes it won’t be directly stated that the assignment is an expository essay, but there are certain keywords that imply expository writing is required. Consider the prompts below.

The word “explain” here is the clue: An essay responding to this prompt should provide an explanation of this historical process—not necessarily an original argument about it.

Sometimes you’ll be asked to define a particular term or concept. This means more than just copying down the dictionary definition; you’ll be expected to explore different ideas surrounding the term, as this prompt emphasizes.

An expository essay should take an objective approach: It isn’t about your personal opinions or experiences. Instead, your goal is to provide an informative and balanced explanation of your topic. Avoid using the first or second person (“I” or “you”).

The structure of your expository essay will vary according to the scope of your assignment and the demands of your topic. It’s worthwhile to plan out your structure before you start, using an essay outline .

A common structure for a short expository essay consists of five paragraphs: An introduction, three body paragraphs, and a conclusion.

Like all essays, an expository essay begins with an introduction . This serves to hook the reader’s interest, briefly introduce your topic, and provide a thesis statement summarizing what you’re going to say about it.

Hover over different parts of the example below to see how a typical introduction works.

In many ways, the invention of the printing press marked the end of the Middle Ages. The medieval period in Europe is often remembered as a time of intellectual and political stagnation. Prior to the Renaissance, the average person had very limited access to books and was unlikely to be literate. The invention of the printing press in the 15th century allowed for much less restricted circulation of information in Europe, paving the way for the Reformation.

The body of your essay is where you cover your topic in depth. It often consists of three paragraphs, but may be more for a longer essay. This is where you present the details of the process, idea or topic you’re explaining.

It’s important to make sure each paragraph covers its own clearly defined topic, introduced with a topic sentence . Different topics (all related to the overall subject matter of the essay) should be presented in a logical order, with clear transitions between paragraphs.

Hover over different parts of the example paragraph below to see how a body paragraph is constructed.

The invention of the printing press in 1440 changed this situation dramatically. Johannes Gutenberg, who had worked as a goldsmith, used his knowledge of metals in the design of the press. He made his type from an alloy of lead, tin, and antimony, whose durability allowed for the reliable production of high-quality books. This new technology allowed texts to be reproduced and disseminated on a much larger scale than was previously possible. The Gutenberg Bible appeared in the 1450s, and a large number of printing presses sprang up across the continent in the following decades. Gutenberg’s invention rapidly transformed cultural production in Europe; among other things, it would lead to the Protestant Reformation.

The conclusion of an expository essay serves to summarize the topic under discussion. It should not present any new information or evidence, but should instead focus on reinforcing the points made so far. Essentially, your conclusion is there to round off the essay in an engaging way.

Hover over different parts of the example below to see how a conclusion works.

The invention of the printing press was important not only in terms of its immediate cultural and economic effects, but also in terms of its major impact on politics and religion across Europe. In the century following the invention of the printing press, the relatively stationary intellectual atmosphere of the Middle Ages gave way to the social upheavals of the Reformation and the Renaissance. A single technological innovation had contributed to the total reshaping of the continent.

An expository essay is a broad form that varies in length according to the scope of the assignment.

Expository essays are often assigned as a writing exercise or as part of an exam, in which case a five-paragraph essay of around 800 words may be appropriate.

You’ll usually be given guidelines regarding length; if you’re not sure, ask.

An expository essay is a common assignment in high-school and university composition classes. It might be assigned as coursework, in class, or as part of an exam.

Sometimes you might not be told explicitly to write an expository essay. Look out for prompts containing keywords like “explain” and “define.” An expository essay is usually the right response to these prompts.

An argumentative essay tends to be a longer essay involving independent research, and aims to make an original argument about a topic. Its thesis statement makes a contentious claim that must be supported in an objective, evidence-based way.

An expository essay also aims to be objective, but it doesn’t have to make an original argument. Rather, it aims to explain something (e.g., a process or idea) in a clear, concise way. Expository essays are often shorter assignments and rely less on research.

Expository Essays

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

The Modes of Discourse—Exposition, Description, Narration, Argumentation (EDNA)—are common paper assignments you may encounter in your writing classes. Although these genres have been criticized by some composition scholars, the Purdue OWL recognizes the wide spread use of these approaches and students’ need to understand and produce them.

What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following.

• A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

• Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

• Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

• Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

• A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

• A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

Expository Writing: Definition and Examples

Table of Contents

What is expository writing, what is an expository paragraph, expository writing examples, how prowritingaid can help you with expository composition.

One of the most common types of writing is expository writing. Whether you’re a student taking an English class or a professional trying to communicate to others in your field, you’ll need to use expository writing in your day-to-day work.

So, what exactly does this term mean?

The short answer is that expository writing refers to any writing designed primarily to explain or instruct.

Read on to learn the definition of expository writing as well as some examples of what this type of writing can look like.

Before we look at examples of expository writing, let’s start with a quick definition of what this term actually means.

Expository Writing Definition

The term expository writing refers to any writing that’s designed to explain something. We use the word expository to describe any passage of writing that’s supposed to present information and help you understand it in an objective way.

Some common examples of expository writing include academic essays, textbooks, instructional guides, and news reports. Good expository writing should be factual, objective, and clear.

To better understand what this term means, think about the difference between a scientific article, a short story, and an advertisement.

The scientific article is considered expository writing because its primary purpose is to explain a particular topic in more detail. It presents data, analyzes what that data means, and focuses on the facts.  

On the other hand, the short story isn’t considered expository writing, because its core purpose isn’t to explain or inform—instead, it’s probably trying to entertain you or to take you on a journey. Short stories are narrative writing.

Similarly, an advertisement isn’t expository writing because its core purpose isn’t to explain or inform—instead, it’s trying to persuade you to buy what it’s selling. Advertisements are persuasive writing.   

Here’s a quick rundown of what expository essays should and shouldn’t do.

An expository essay should:

Teach the reader about a particular topic

Focus on the facts

Follow a clearly organized structure

Present information and details from credible sources

An expository essay should not:

Try to change the reader’s mind about something

Present the author’s personal opinions

Include made-up narratives or stories

Follow experimental or nonlinear structures

An expository paragraph is exactly what it sounds like—a paragraph of expository writing.

A well-written expository paragraph should follow a specific format to make it as clear and easy to read as possible. Most expository paragraphs do the following things:

Start with a topic sentence, which explains what the paragraph will be about

Then, include 3 – 5 body sentences that provide supporting details for the topic sentence

Finally, wrap things up with a closing sentence that summarizes what the paragraph has said

Writing an expository paragraph is a great way to practice expository writing. That’s because the paragraph follows the same structure as a more complex expository essay, just on a smaller scale.

Most expository essays should follow this format:  

Start with an introductory paragraph that includes the thesis statement, which tells the reader the core statement of the essay

Then, include 3 – 5 body paragraphs that provide factual evidence to support the thesis statement

Finally, wrap things up with a concluding paragraph that summarizes what the body paragraphs and thesis statement said

You can see the similarities between the two formats. If you can write a fantastic expository paragraph, you’ll be well-prepared to move on to writing a full expository essay.

Example of Expository Paragraph

Here’s an example of an expository paragraph that follows the structure described above.

The leading cause of death in the United States is heart disease, which can be fatal if it leads to heart attack or cardiac arrest. Heart attacks occur when a blockage in the coronary artery prevents oxygenated blood from reaching the heart. Cardiac arrests occur when the heart stops pumping entirely, which prevents the patient from breathing normally. Both of these problems can be deadly, even in seemingly healthy people who don’t have noticeable risk factors. As a result, heart disease is an important problem that many doctors and scientists are researching.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

There are many ways you can present information in an expository essay. Here are four of the most popular ways, along with examples of each one.  

Problem and Solution Essay

A problem and solution essay presents the reader with a problem and then considers possible solutions to that problem. 

Here’s an example passage you might find in a problem and solution essay:

Among the many proposed solutions to rising carbon emissions, one promising possibility is carbon trapping. Scientists are figuring out how to pull carbon emissions out of the atmosphere and trap it in less harmful forms, such as by injecting carbon dioxide underground so it will turn to stone.

Compare and Contrast Essay

This type of essay takes two subjects and compares and contrasts them. It focuses on highlighting the differences and similarities between those two things.

Here’s an example passage of this type of expository writing:

Though country music and R&B music have very different sounds, they also share many similarities. For one thing, both types of music embody a specific cultural identity. For another, both genres trace their roots back to the 1920s, when the Victor Talking Machine Company signed singers from the American South.

Classification Essay

In a classification essay, you describe the categories within a certain group of things.  

Here’s an example passage you might find in a classification essay:

There are three ways in which artificial intelligence might become stronger than humans in the future: high speed, high collective intelligence, and high quality. A speed AI would be able to perform calculations and experience the world much faster than humans. A collective intelligence, like a hive mind, would be able to break down a complex task into several parts and pursue them simultaneously. Finally, a quality AI would simply be able to solve more complex problems than humans could.

Process Essay

In a process essay, you give the reader the steps for completing a specific process. This is similar to a how-to guide or an instruction manual.   

Here’s an example passage you might find in this type of expository writing:

Caramelize the chopped onions in a frying pan. When the onions have caramelized, mix in the bell peppers, mushrooms, and tomatoes and stir for 4 – 6 minutes or until all the ingredients have softened. If you want to add meat, you can add ground beef and cook for another 4 – 6 minutes. Season with salt and pepper to taste.  

Good expository writing should be easy to read. After all, the purpose of exposition is to explain things to your readers, and you won’t be able to accomplish that if they have trouble understanding your writing.

That’s why ProWritingAid can help you write an expository essay. The grammar checker can help you ensure your sentences flow well, you’re not missing any necessary punctuation, and all your words are precise and clear.

Expository Essay

Definition of expository essay.

Expose means to uncover or lay something bare, or to discover something in a way that others know what it is. Expository is derived from exposition , which is a noun of ‘expose.’ An expository essay is a genre of writing which tends to explain, illustrate, clarify, or explicate something in a way that it becomes clear for readers. Therefore, it could be an investigation, evaluation, or even argumentation about an idea for clarification.

Types of Expository Essay

Expository essay is further divided into five major categories .

• Descriptive Essay : A descriptive essay describes something, some place, some experience, or some situation through sensory information.
• Process Essay : A process essay explains or shows a process of making or doing something.
• Comparison Essay : A comparison essay makes comparison and contrasts between two things.
• Cause/Effect Essay : A cause and effect essay finds out the cause of something and then its effects on something else.
• Problem/Solution Essay : A problem/solution essay presents a problem and its solution for readers.

Difference Between an Expository Essay and an Argumentative Essay

As is clear, an expository essay is an exposition, explanation, investigation, or illustration for the purpose of clarification, therefore, its tone is often kept neutral. However, in an argumentative essay , a clear position about something is taken before the argument is presented. There is no issue of objectivity or neutrality.

Examples of Expository Essay in Literature

Example #1: how chinese mothers are superior (by amy chua).

“I’m using the term ‘Chinese mother’ loosely. I know some Korean, Indian, Jamaican, Irish and Ghanaian parents who qualify too. Conversely, I know some mothers of Chinese heritage, almost always born in the West, who are not Chinese mothers, by choice or otherwise. I’m also using the term ‘Western parents’ loosely. Western parents come in all varieties. All the same, even when Western parents think they’re being strict, they usually don’t come close to being Chinese mothers. For example, my Western friends who consider themselves strict make their children practice their instruments 30 minutes every day. An hour at most. For a Chinese mother, the first hour is the easy part. It’s hours two and three that get tough.”

This is an excerpt from a comparison/ contrast essay by Amy Chua, which explains how mothers are different in different cultures. This paragraph compares mothers from Chinese, Iranian, Jamaican, and Irish contexts .

Example #2: Learning to Read (by Malcolm X)

“It was because of my letters that I happened to stumble upon starting to acquire some kind of a homemade education. I became increasingly frustrated at not being able to express what I wanted to convey in letters that I wrote, especially those to Mr. Elijah Muhammad. In the street, I had been the most articulate hustler out there. I had commanded attention when I said something. But now , trying to write simple English, I not only wasn’t articulate, I wasn’t even functional. How would I sound writing in slang , the way I would say it, something such as, ‘Look, daddy , let me pull your coat about a cat, Elijah Muhammad — ‘ Many who today hear me somewhere in person, or on television, or those who read something I’ve said, will think I went to school far beyond the eighth grade. This impression is due entirely to my prison studies.”

This passage has been taken from a process essay. In this essay, Malcolm X tells the process of his learning. In this paragraph, he gives full detail how he learns letters.

Example #3: Summer Ritual (by Ray Bradbury)

“About seven o’clock you could hear the chairs scraping from the tables, someone experimenting with a yellow-toothed piano , if you stood outside the dining-room window and listened. Matches being struck, the first dishes bubbling in the suds and tinkling on the wall racks, somewhere, faintly, a phonograph playing. And then as the evening changed the hour, at house after house on the twilight streets, under the immense oaks and elms , on shady porches, people would begin to appear, like those figures who tell good or bad weather in rain -or-shine clocks. Uncle Bert, perhaps Grandfather, then Father, and some of the cousins; the men all coming out first into the syrupy evening, blowing smoke, leaving the wSWomen’s voices behind in the cooling-warm kitchen to set their universe aright. Then the first male voices under the porch brim, the feet up, the boys fringed on the worn steps or wooden rails where sometime during the evening something, a boy or a geranium pot, would fall off.”

This is an example of a passage from a descriptive essay. It has full description which tells us about sounds and colors; a type of sensory information.

Functions of an Expository Essay

The function of an expository essay is to clarify and expose things, ideas, persons, and places through description, process, comparison/contrast, or through problem solution. The objective of this type of essay is to make readers aware of things given in the essay. It proves full and detailed information in a way that readers become knowledgeable about the topic.

expository essay

What is expository essay definition, usage, and literary examples, expository essay definition.

An  expository essay  [ik-SPOZ-ih-tohr-ee ess-ay] is an essay in which the writer researches a topic and uses evidence to inform their readers or clarify the topic. They can take many forms, including a how-to essay, an essay that defines something, or an essay that studies a problem and offers a solution.

The Five-Paragraph Model

Most expository essays follow the five-paragraph essay model:

• Introduction:  The introduction contains the thesis statement or main point of the essay. Here, the writer describes the subject and gives necessary  context .
• Body:  This section is usually three or more paragraphs and offers supporting evidence for the thesis.
• Conclusion:  The conclusion revisits the thesis and summarizes the writer’s main points.

Types of Expository Essays

There are several types of expository essays that can be written.

• Cause and Effect:  These essays question why something happened and the outcome of that occurrence. For example, an essay of this type might question why there’s a large homeless population in Seattle and what effects it has on the city and its citizens.
• Classification:  These break a broad subject down into several, in-depth subcategories. A classification essay might study the various kinds of movies, define genres, and break the most common genres down by subgenre (for example, action thriller and action adventure as subgenres of the action genre).
• Compare and Contrast:  These essays lay out the similarities and differences of at least two subjects. One such essay might compare two different novels by the same author. These essays can explore the pros and cons of different choices as well, like living in the city versus living in the country.
• Definition:  As indicated, a definition essay describes or defines something. For example, it might define the internet and provide a detailed explanation of how it works.
• How-To:  Also called a process essay, a how-to essay gives the reader steps for creating or doing something. For example, a process essay might walk its reader through setting a table, step by step.
• Problem and Solution:  This type of essay explores a problem and, using evidential support, offers potential solutions. For example, a writer might consider the example of Seattle’s homeless population, cite a solution that other cities have used successfully, and propose that same solution for Seattle.

Other Forms of Expository Writing

In addition to the aforementioned, there are other uses for expository writing. Most commonly:

• Newspaper articles
• Encyclopedic entries
• Manuals/assembly instructions

Expository vs. Argumentative Essays

Expository essays are like argumentative essays in that they both require research. Unlike argumentative essays, expository essays are meant to inform their audience rather than persuade it.

Argumentative essays are often controversial and contain the writer’s personal opinions, whereas expository essays give factual information and explore a topic from many  perspectives . Educational spheres often use expository essays to test writing ability, reading comprehension, and/or the writer’s understanding of a topic.

Examples of Expository Essays

1. Susan Sontag, “Notes on ‘Camp’”

This is a definition essay that explores the meaning and usage of the slang word  camp . When she wrote the essay in 1964, people used the word to describe a person or thing as exaggerated, effeminate, or theatrical. Sontag suggests that camp isn’t a solid concept but rather a sensibility, and she acknowledges its connection to contemporary gay culture. Her definition of camp is given in the following passage:

[Camp] is not a natural mode of sensibility, if there be any such. Indeed the essence of Camp is its love of the unnatural: of artifice and exaggeration. And Camp is esoteric–something of a private code, a badge of identity even, among small urban cliques.

2. David Foster Wallace, “Consider the Lobster”

Herein, Wallace reviews the 2003 Main Lobster Festival and questions the morality of boiling lobsters alive. He examines the problem from all facets, including whether a lobster feels pain, without directly asserting his opinion. After descriptions of the festival, physical properties of lobsters, and the common use of the crustaceans, Wallace poses the main question of the essay:

So then here is a question that’s all but unavoidable at the World’s Largest Lobster Cooker, and may arise in the kitchens across the U.S. Is it all right to boil a sentient creature alive just for our gustatory pleasure? A related set of concerns: Is the previous question irksomely PC or sentimental? What does “all right” even mean in this context? Is it all just a matter of individual choice?

3. Rebecca Solnit, “The Longest War”

From Solnit’s 2014 book of essays,  Men Explain Things to Me , “The Longest War” explores issues of male violence against women. Solnit uses both statistical and  anecdotal  evidence to inform her audience of the issue, which supports some of her argumentative essays that appear later in the book:

[T]hough a rape is reported only every 6.2 minutes in this country, the estimated total is perhaps five times as high. Which means that there may be very nearly a rape a minute in the United States. It all adds up to tens of millions of rape victims. A significant portion of the women you know are survivors.

What Is an Expository Essay?

An essay that explains a writer’s ideas by defining, explaining, informing, or elaborating on points to allow the reader to clearly understand the concept.

Many of your future academic workplace writing assignments will be expository–explaining your ideas or the significance of a concept or action. An expository essay allows the writer the opportunity to explain his or her ideas about a topic and to provide clarity for the reader by using:

• Explanations
• Definitions

It may also include the writer outlining steps of a procedure in a way that is straightforward for the reader to follow. It is purely informative and often contains elements of summary.

Imagine you need to verbally explain a concept to your classmates, maybe a behavioural theory. What are the key elements on which you would focus? How would you organize the information? You could explain who came up with the theory, the specific area of study to which it is related, its purpose, and the significant details to explain the theory. Telling these four elements to your classmates would give them a complete, yet summarized, picture of the theory, so they could apply the theory in future discussions.

Although you did this verbally, you were still fulfilling the elements of an expository essay by providing definition, details, explanations, and maybe even facts if you have a really good memory. This is the same process that you would use when you write an expository essay. You may actually be doing this all the time; for example, when you are giving someone directions to a place or explaining how to cook something. In the following sections of the chapter, you will practise doing this more in different expository written forms.

The Structure of an Expository Essay

Sections versus paragraphs.

Before looking at the general structure of an expository essay, you first need to know that in your post-secondary education, you should not consider your essay as writing being constructed with five paragraphs as you might have been used to in high school. You should instead think of your essay in terms of sections (there may be five), and each section may have multiple paragraphs.

To understand further why you need to think beyond the five-paragraph essay, imagine you have been asked to submit a six-page paper (approximately 1,500 words). You already know that each paragraph should be roughly 75 to 200 words long. If you divide the required word count by five paragraphs (1,500 by 5), you end with 300 words per paragraph, way above the number you should have in a paragraph. If your paragraphs are too long, they likely have too many ideas and your reader may become confused. Your paragraphs should be two-third of a page at most, and never longer than a page.

Instead, if you think of your essays being divided into sections (with possibly more than one paragraph per section), your writing will likely be more organized and allow your reader to follow your presentation of ideas without creating too much distance between your paragraph’s supporting points and its topic sentence.

As you will see in Section 4.5: Classification , some essay forms may require even more than five paragraphs or sections because of how many points are necessary to address. . For the rest of this chapter, the term paragraph will also imply section.

Sections of an Expository Essay

An expository essay, regardless of its purpose, should have at least five sections, which are:

• Introduction
• First body section/paragraph
• Second body section/paragraph
• Third body section/paragraph

The introduction should state the topic of your paper: your thesis statement as well as brief signposts of what information the rest of the paper will include. That is, you only want to mention the content of the body paragraphs; you do not want to go in to a lot of detail and repeat what will be in the rest of the essay.

The first body section or paragraph should focus on one of your main points and provide evidence to support that point. There should be two to three supporting points: reasons, facts, statistics, quotations, examples, or a mix of these. Both the second and third body sections should follow the same pattern. Providing three body sections with one point each that supports the thesis should provide the reader with enough detail to be convinced of your argument or fully understand the concept you are explaining. However, remember that some sections will require more explanation, and you may need to separate this information into multiple paragraphs.

You can order your sections in the most logical way to explain your ideas. For example, if you are describing a process, you may use chronological order to show the definite time order in which the steps need to happen. You will learn about the different ways to organize your body paragraphs in the next chapter.

The concluding paragraph , or conclusion, can be a little tricky to compose because you need to make sure you give a concise summary of the body paragraphs, but you must be careful not to simply repeat what you have already written. Look back at the main idea of each section/paragraph, and try to summarize the point using words different from those you have already used. Do not include any new points in your concluding paragraph.

Consider Your Audience: How Much Do They Know?

Later in this chapter, you will work on determining and adapting to your audience when writing, but with an expository essay, since you are defining or informing your audience on a certain topic, you need to evaluate how much your audience knows about that topic (aside from having general common knowledge). You want to make sure you are giving thorough, comprehensive, and clear explanations on the topic. Never assume the reader knows everything about your topic (even if it is covered in the reader’s field of study). For example, even though some of your instructors may teach criminology, they may have specialized in different areas from the one about which you are writing; they most likely have a strong understanding of the concepts but may not recall all the small details on the topic. If your instructor specialized in crime mapping and data analysis for example, he or she may not have a strong recollection of specific criminological theories related to other areas of study. Providing enough background information without being too detailed is a fine balance, but you always want to ensure you have no gaps in the information, so your reader will not have to guess your intention. Again, we will practise this more in Section 4.10: Purpose, Audience, Tone, and Content .

What Comes Next?

In the next eight sections (4.2 through 4.9), we will look at different expository modes, or rhetorical modes, you will often be assigned.

H5P: Let’s take a moment to see how much you already know about types of Expository Essays. Match the type of Expository Essay to the most correct description.

Descriptions:

• the art of storytelling
• to show or demonstrate something clearly
• writing that appeals to our senses
• to break down broad subjects into smaller parts
• to explain how to do something or how something works
• establish the way in which people communicate ideas
• analyze two subjects in relation to each other
• to determine how various phenomena relate

Expository Essay Type:

• Process analysis
• Illustration
• Compare and contrast
• Description
• Cause and effect
• Classification

Answer Key:

Rhetorical modes refers simply to the ways to communicate effectively through language. As you read about these modes, keep in mind that the rhetorical mode a writer chooses depends on his or her purpose for writing. Sometimes writers incorporate a variety of modes in any one essay. In this chapter, we also emphasize the rhetorical modes as a set of tools that will allow you greater flexibility and effectiveness in communicating with your audience and expressing your ideas.

In a few weeks, you will need to submit your first essay–an expository sample–and you will be given the choice of topic: one from each of the modes. Think about which types of expository essays are easier and which are more challenging for you. As mentioned, as you progress through your studies, you will be exposed to each of these types. You may want to explore a mode you find more challenging than the others in order to ensure you have a full grasp on developing each type. However, it is up to you. As you work through the sections, think about possible topics you may like to cover in your expository essay and start brainstorming as you work through the self-practice exercises.

After we explore each of the individual modes in the eight sections that follow, we will look at outlining and drafting; it is at this point you will want to fine tune and narrow the topic you will write about, so you can focus on that when doing the exercises.

How to Write Excellent Expository Essays

WHAT IS AN EXPOSITORY ESSAY?

An Expository essay ‘exposes’ information to the reader to describe or explain a particular topic logically and concisely.

The purpose of expository writing is to educate or inform the reader first and foremost.

Though the term is sometimes used to include persuasive writing , which exposes us to new ways of thinking, a true expository text does not allow the writer’s personal opinion to intrude into the text and should not be confused.

Expository Writing follows a structured format with an introduction, body paragraphs presenting information and examples, and a conclusion summarising key points and reinforcing the thesis. Common expository essays include process, comparison/contrast, cause and effect, and informative essays.

EXPOSITORY ESSAY STRUCTURE

TEXT ORGANIZATION Organize your thoughts before writing.

CLARITY Use clear and concise wording. There is no room for banter.

THESIS STATEMENT State position in direct terms.

TOPIC SENTENCE Open each paragraph with a topic sentence.

SUPPORTING DETAIL Support the topic sentence with further explanation and evidence.

LINK End each body paragraph by linking to the next.

EXPOSITORY ESSAY TYPES

PROCESS Tell your audience how to achieve something, such as how to bake a cake.

CAUSE & EFFECT Explore relationships between subjects, such as climate change and its impact.

PROBLEM & SOLUTION Explain how to solve a problem, such as improving physical fitness.

COMPARE & CONTRAST Compare and contrast two or more items, such as life in China life vs life in the United States or Australia.

DEFINITION Provides a detailed definition of a word or phrase, such as self-confidence.

CLASSIFICATION Organizes things into categories or groups, such as types of music.

STRUCTURE & FEATURES OF EXPOSITORY WRITING

While there are many types of expository essays, the basic underlying structure is the same. The Hamburger or 5-Paragraph Essay structure is an excellent scaffold for students to build their articles. Let’s explore the expository essay outline.

INTRODUCTION:

This is the top bun of the burger, and here the student introduces the exposition topic. This usually consists of a general statement on the subject, providing an essay overview. It may also preview each significant section, indicating what aspects of the subject will be covered in the text. These sections will likely relate to the headings and subheadings identified at the planning stage.

If the introduction is the top bun of the burger, then each body paragraph is a beef patty. Self-contained in some regards, each patty forms an integral part of the whole.

EXPOSITORY PARAGRAPHS

Each body paragraph deals with one idea or piece of information. More complex topics may be grouped under a common heading, and the number of paragraphs will depend on the complexity of the topic. For example, an expository text on wolves may include a series of paragraphs under headings such as habitat, breeding habits, what they eat, etc.

Each paragraph should open with a topic sentence indicating to the reader what the paragraph is about. The following sentences should further illuminate this main idea through discussion and/or explanation. Encourage students to use evidence and examples here, whether statistical or anecdotal. Remind students to keep things factual – this is not an editorial piece for a newspaper!

Expository writing is usually not the place for flowery flourishes of figurative imagery! Students should be encouraged to select a straightforward language that is easy for the reader to understand. After all, the aim here is to inform and explain, and this is best achieved with explicit language.

As we’ve seen, several variations of the expository essay exist, but the following are the most common features students must include.

The title should be functional. It should instantly inform the reader what they will learn about in the text. This is not the place for opaque poetry!

A table of contents in long essays will help the reader locate helpful information quickly. Usually, the page numbers found here will be linked to headings and subheadings to be found in the text.

HEADINGS / SUBHEADINGS:

These assist the reader in finding information by summarizing the content in their wording.

Usually listed alphabetically, the glossary defines unusual or topic-specific vocabulary and is sometimes accompanied by pictures, illustrations etc.

The index lets the reader identify where to find specific information in longer texts. An index is much more detailed than a table of contents.

VISUAL FORMS OF INFORMATION

Expository essays sometimes support the text with visuals, such as:

• Pictures / Illustrations / Photographs:

These can be used to present a central idea or concept within the text and are often accompanied by a caption explaining what the image shows. Photographs can offer a broad overview or a close-up of essential details.

Diagrams are a great way to convey complex information quickly. They should be labelled clearly to ensure the reader knows what they are looking at.

• Charts and Graphs:

These are extremely useful for showing data and statistics in an easy-to-read manner. They should be labelled clearly and correspond to the information in the nearby text.

Maps may be used to explain where something is or was located.

Types of expository essay

There are many different types of expository texts (e.g. encyclopaedias, travel guides, information reports , etc.), but there are also various expository essays, with the most common being.

• Process Essays
• Cause and Effect Essays
• Problem and Solution Essays
• Compare and Contrast Essays
• Definition Essays
• Classification Essays

We will examine each of these in greater detail in the remainder of this article, as they have slight nuances and differences that make them unique. The graphic below explains the general structure for all text types from the expository writing family.

THE PROCESS ESSAY

This how-to essay often takes the form of a set of instructions. Also known as a procedural text , the process essay has very specific features that guide the reader on how to do or make something.

To learn more about this type of writing, check out our information-packed article here .

Features of a process essay

Some of the main features of the process essay include:

• ‘How to’ title
• Numbered or bullet points
• Time connectives
• Imperatives (bossy words)
• List of resources

Example Expository Process Essay:

The cause and effect essay.

The purpose of a cause-and-effect essay is to explore the causal relationships between things. Essays like this often bring the focus back to a single cause. These essays frequently have a historical focus.

The text should focus on facts rather than assumptions as an expository essay. However, cause-and-effect essays sometimes explore hypothetical situations too.

There are two main ways to structure a cause-and-effect essay.

The Block Structure presents all the causes first. The writer then focuses on the effects of these causes in the second half of the essay.

The Chain Structure presents each cause and then immediately follows with the effects it created.

Example Expository Cause and Effect Essay:

The problem and solution essay.

In this type of essay, the writer first identifies a problem and then explores the topic from various angles to ultimately propose a solution. It is similar to the cause-and-effect essay.

While the problem and solution essay can use the block and chain structures as outlined above – substitute cause with problem and effect with a solution – it will also usually work through the following elements:

• Identifies a problem
• Contains a clear thesis statement
• Each paragraph has a topic sentence
• Supports with facts, examples, evidence
• The conclusion summarizes the main points

Suggested Title: What Can Be Done to Prevent Bullying in Schools?

Example Expository Problem and Solution Essay:

The compare and contrast essay.

In this type of essay, students evaluate the similarities and differences between two or more things, ideas, people, etc. Usually, the subjects will belong to the same category.

The compare-and-contrast expository essay can be organized in several different ways. Three of these are outlined below.

In the three structures outlined, it is assumed that two subjects are being compared and contrasted. Of course, the precise number of paragraphs required in the text will depend on the number of points the student wishes to make and the number of subjects being compared and contrasted.

Suggested Title: In-Class or Remote Learning: Which Is Best?

DEFINITION ESSAYS

This type of essay provides a detailed description and definition of a word or phrase. It can be a concrete term, such as car or glass, or a more abstract concept, such as love or fear .

A definition essay comprehensively explains a term’s purpose and meaning. It will frequently contain some or all of the following elements:

• A definition of the term
• An analysis of its meaning
• The etymology of the term
• A comparison to related terms
• Examples to illustrate the meaning
• A summary of the main points

Example Expository Definition Essay:

CLASSIFICATION ESSAYS

Like definition essays, a classification essay sorts or organizes things into various groups or categories and explains each group or category in detail.

Classification essays focus on:

• Sorting things into functional categories
• Ensuring each category follows a common organizing principle
• Provides examples that illustrate each category.

Example Expository Classification Essay:

One of the best ways to understand the different features of expository essays is to see them in action. The sample essay below is a definition essay but shares many features with other expository essays.

EXPOSITORY WRITING PROMPTS

Examples of Expository Essay Titles

 Expository essay prompts are usually pretty easy to spot.

 They typically contain keywords that ask the student to explain something, such as “define,” “outline,” “describe,” or, most directly of all, “explain.”

 This article will examine the purpose of an expository essay and its structure. It will also examine the primary language and stylistic features of this vital text type.

 After this, we’ll explore five distinct tips for helping your students get the most out of writing their expository essays.

Expository Essays vs Argumentative Essays

 Expository essays are often confused with their close cousin, the argumentative essay. Still, it’s easy to help students distinguish between the two by quickly examining their similarities and differences.

 In an expository essay, students will attempt to write about a thing or a concept neutrally and objectively, unlike an argumentative essay where the writer’s opinions permeate the text throughout. Simple as it sounds, this may take some doing for some students as it requires the writer to refine their personal voice almost out of existence!

 Luckily, choosing the correct viewpoint from which to write the essay can go a long way to helping students achieve the desired objectivity. Generally, students should write their expository essays from the third-person perspective.

Contrastingly, argumentative essays are subjective in nature and will usually be written from the first-person perspective as a result.

 In an expository essay, the text’s prime focus is the topic rather than the writer’s feelings on that topic. For the writer, disassociating their personal feelings on a topic is much easier when they’re a step removed from the narration by using the third-person POV rather than the first-person POV.

Expository Essay Tips

Follow these top tips from the experts to craft an amazing expository essay.

 Tip #1: Choose the Right Tool for the Job

Surprising as it may seem, not all expository essays are created equal.

 In fact, there are several different types of expository essays, and our students must learn to recognize each and choose the correct one for their specific needs when producing their own expository essays.

 To do this, students will need to know the 5 types of expository essays:

• The Cause and Effect Essay : This type of essay requires that the writer explain why something happened and what occurred due to that event and subsequent events. It explores the relationship between people, ideas, events, or things and other people, ideas, events, or things.
• The Compare and Contrast Essay: In a compare and contrast essay, the writer examines the similarities and differences between two subjects or ideas throughout the body of the piece and usually brings things together in an analysis at the end .
• The Descriptive Essay: This is a very straightforward expository essay with a detailed description or explanation of a topic. The topic may be an event, place, person, object, or experience. This essay’s direct style is balanced with the freedom of the writer can inject some of their creativity into the description.
• The Problem and Solution Essay : In this expository essay, the student will work to find valid solutions to a specific problem or problem.
• The Process Essay : Also called a how-to essay, this essay type is similar to instruction writing, except in essay form. It provides a step-by-step procedure breakdown to teach the reader how to do something.

 When choosing a specific topic to write about, students should consider several factors:

 ●      Do they know the topic well enough to explain the ins and outs of the subject to an unfamiliar audience?

 ●      Do they have enough interest in this topic to sustain thorough research and writing about it?

 ●      Is enough relevant information and credible sources available to fuel the student’s writing on this topic?

Tip # 2: Research the Topic Thoroughly

Regardless of which type of expository essay your students are working on, they must approach the research stage of the writing process with diligence and focus. The more thorough they are at the research stage, the smoother the remainder of the writing process will be.

A common problem for students while researching is that sometimes they don’t have a clear understanding of the objective of their research. They lack a clear focus on their efforts.

Research is not mindlessly scanning documents and scrawling occasional notes. As with any part of the writing process, it begins with determining clear objectives.

Often, students will start the research process with a broad focus, and as they continue researching, they will naturally narrow their focus as they learn more about the topic.

Take the time to help students understand that writing isn’t only about expressing what we think; it’s also about discovering what we think.

When researching, students should direct their efforts to the following:

• Gather Supporting Evidence : The research process is not only for uncovering the points to be made within the essay but also the evidence to support those points. The aim here is to provide an objective description or analysis of the topic; therefore, the student will need to gather relevant supporting evidence, such as facts and statistics, to bolster their writing. Usually, each paragraph will open with a topic sentence, and subsequent sentences in the paragraph will focus on providing a factual, statistical, and logical analysis of the paragraph’s main point.
• Cite Sources : It’s an essential academic skill to be able to cite sources accurately. There are several accepted methods of doing this, and you must choose a citation style appropriate to your student’s age, abilities, and context. However, whatever style you choose, students should get used to citing any sources they use in their essays, either in the form of embedded quotations, endnotes, or bibliography – or all three!
• Use Credible Sources: The Internet has profoundly impacted knowledge sharing as the Gutenberg Press did almost 600 years ago. It has provided unparalleled access to the sum total of human knowledge as never before, with each student having a dizzying number of sources available at their fingertips. However, we must ensure our students understand that not all sources are created equal. Encourage students to seek credible sources in their research and filter out the more dubious sources. Some questions students can ask themselves to help determine a source’s credibility include:

●      Have I searched thoroughly enough to find the most relevant sources for my topic?

●      Has this source been published recently? Is it still relevant?

●      Has the source been peer-reviewed? Have other sources confirmed this source?

●      What is the publication’s reputation?

●      Is the author an expert in their field?

●      Is the source fact-based or opinion-based?

Tip #3: Sketch an Outline

Every kid knows you can’t find the pirate treasure without a map, which is true of essay writing. Using their knowledge of the essay’s structure, students start whipping their research notes into shape by creating an outline for their essay.

The 5-paragraph essay or ‘Hamburger’ essay provides a perfect template for this.

Students start by mapping out an appealing introduction built around the main idea of their essay. Then, from their mound of research, they’ll extract their most vital ideas to assign to the various body paragraphs of their text.

Finally, they’ll sketch out their conclusion, summarize their essay’s main points, and, where appropriate, make their final statement on the topic.

Tip #4: Write a Draft

Title chosen? Check! Topic researched? Check! Outline sketched? Check!

Well, then, it’s time for the student to begin writing in earnest by completing the first draft of their essay.

They’ll already have a clear idea of the shape their essay will take from their research and outlining processes, but ensure your students allow themselves some leeway to adapt as the writing process throws up new ideas and problems.

That said, students will find it helpful to refer back to their thesis statement and outline to help ensure they stay on track as they work their way through the writing process towards their conclusions.

As students work through their drafts, encourage them to use transition words and phrases to help them move smoothly through the different sections of their essays.

Sometimes, students work directly from an outline as if on a checklist. This can sometimes be seen as the finished essay resembling Frankenstein. That is an incongruous series of disparate body parts crudely stitched together.

Learning to use transitions effectively will help students create an essay that is all of a whole, with all the joins and seams sanded and smoothed from view.

Tip #5: Edit with a Fresh Pair of Eyes

Once the draft is complete, students enter the final crucial editing stage.

But, not so hasty! Students must pencil in some time to let their drafts ‘rest’. If the editing process occurs immediately after the student finishes writing their draft, they’ll likely overlook much.

Editing is best done when students have time to gain a fresh perspective on their work. Ideally, this means leaving the essay overnight or over a few nights. However, practically, this isn’t always possible. Usually, though, it will be possible for students to put aside their writing for a few hours.

With the perspective that only time gives, when returning to their work, students can identify areas for improvement that they may have missed. Some important areas for students to look at in the editing process include:

• Bias : Students need to remember the purpose of this essay is to present a balanced and objective description of the topic. They need to ensure they haven’t let their own personal bias slip through during the writing process – an all too easy thing to do!
• Clarity : Clarity is as much a function of structure as language. Students must ensure their paragraphs are well organized and express their ideas clearly. Where necessary, some restructuring and rewriting may be required.
• Proofread: With stylistic and structural matters taken care of, it’s now time for the student to shift their focus onto matters of spelling , vocabulary choice, grammar, and punctuation. This final proofread represents the last run-through of the editing process. It’s the students’ final chance to catch mistakes and errors that may bias the assessor (aka You! ) against the effectiveness of the piece of writing. Where the text has been word-processed, the student can enlist inbuilt spelling and grammar checkers to help. Still, they should also take the time to go through each line word by word. Automatic checkers are a helpful tool, but they are a long way from infallible, and the final judgement on a text should employ the writer’s own judgement.

Expository essays are relatively straightforward pieces of writing. By following the guidelines mentioned above and practising them regularly, students can learn to produce well-written expository essays quickly and competently.

Explaining and describing events and processes objectively and clearly is a useful skill that students can add to their repertoire. Although it may seem challenging at first, with practice, it will become natural.

To write a good expository essay, students need a good understanding of its basic features and a firm grasp of the hamburger essay structure. As with any writing genre, prewriting is essential, particularly for expository writing.

Since expository writing is designed primarily to inform the reader, sound research and note-taking are essential for students to produce a well-written text. Developing these critical skills is an excellent opportunity for students through expository writing, which will be helpful to them as they continue their education.

Redrafting and editing are also crucial for producing a well-written expository essay. Students should double-check facts and statistics, and the language should be edited tightly for concision.

And, while grading their efforts, we might even learn a thing or two ourselves!

What are the characteristics of expository essay?

Expository papers are factual and objective. They have a clear purpose, and their structure is linear and logical. In such essays, writers don’t share their opinions and don’t try to persuade readers.

Expository essays:

What Is the Purpose of an Expository Essay?

The purpose of an expository essay is to present information and explain a topic. No personal opinions or biased statements are here, just facts with evidence.

The main focus is logic and coherence.

I’ve found the method for you to remember expository essays’ organization. It’s POET:

• P — Purpose: analyze, tell, explain, and connect the information.
• O — Organization: do research, outline, and structure your paper.
• E — Evidence: use facts, statistics, expert quotes, and examples.
• T — Thesis: be concise and straightforward.

Expository vs. Argumentative

An easy way to understand the meaning and purpose of explanatory papers is to compare them with other text types. Students most often confuse expository essays with argumentative (persuasive) ones. The above table demonstrates the differences for you to remember.

Types of Expository Writing

As a rule, teachers mention the type of expository essay in the assigned prompt. It helps you understand how to structure and present the information in your paper.

The five types of expository writing are:

• Definition. These papers describe and explain concepts. You just tell readers about something: a person, a place, a situation, etc.
• Classification. Here you need to break a broad concept into subcategories. Start with a general topic, and then tell about each subgroup. (Example: an essay about movie genres, cat breeds, book styles, etc.)
• Process (how-to). These texts explain to readers how to create or do something. Give instructions, steps, and practical tips. We also know process essays as problem-solution papers. A writer introduces and describes a problem and then tells the audience how to solve it.
• Compare-and-Contrast. Here you tell about the similarities and differences between at least two subjects. Or, you can describe the pros and cons of something. (Example: compare two novels of the same author; pros and cons of living in a village; etc.)
• Cause-and-Effect. These essays explain why something happened and what the outcome was. (Example: why Executed Renaissance (1) happened in Ukraine in the 1930s and what effects it has now.)

Expository Essay Structure

In academia, expository essays are standard 5-paragraph papers. You write an introduction, three body paragraphs, and a conclusion.

Below is more information on what to include in every paragraph.

Introduction

The introduction of expository essays includes the topic and the main idea. Three elements to write here:

• A writing hook to grab the reader’s interest
• A topic’s background (introducing the topic)
• A thesis statement summarizing the main idea (what you’ll tell about the subject)

Here’s an example:

Body Paragraphs

Expository papers have at least three body paragraphs, each exposing one idea. It’s critical to craft logical transitions between paragraphs and include evidential support.

Each paragraph should have a logical connection to the thesis statement. As for evidence, use statistics, citations, and other info you’ve got when researching. (2)

Here go your four E’s to consider:

• Explanations
• Elaboration

That’s what a body paragraph of your expository paper might look like:

Three elements to include:

• Topic sentence (to state what this paragraph will be about)
• Explanation of the topic in detail
• Concluding sentences with a logical transition to the next paragraph

The final paragraph restates the thesis, given the evidence you provided in the essay. Summarize the topic, but don’t introduce any new information. Leave readers with a positive impression of your work.

Three elements of expository essay conclusions:

• Readdressing the thesis in light of the provided information
• A brief overview of the essay’s key points
• The key takeaway for readers to remember from your essay

Expository Essay Format

Example of expository essay.

Below is your example of expository writing to see the structure and format. It’s a standard five-paragraph essay students write in college. The number of words and paragraphs may differ depending on the prompt you get from teachers.

Feel free to use it for inspiration and a better understanding of how to write:

What is the primary purpose of an expository text?

The primary purpose of an expository text is to inform readers about the topic. Such texts describe and explain concepts to educate the audience. They are objective. A writer shouldn’t express personal opinions or attempt to persuade readers. Expository essays are descriptive, not argumentative or persuasive.

How to write an expository essay?

First, review the prompt; it will tell you all the instructions. You’ll know a topic, a word count, a format, etc. Then, do research and gather all the information about your subject. What will you tell the readers? What evidence you’ll use to support your points? Once ready, create an outline. You’ll need to specify the thesis statement and think about how you structure an essay. Finally, write a draft and proofread and edit it before submitting it to a teacher’s review.

What is typically included in the introductory section of an expository essay?

An introductory paragraph starts with a hook to grab readers’ attention to the topic. Then, provide a topic’s background for readers to understand what you write about. Finally, finish your introduction with a thesis statement. In the thesis, summarize the main idea of your paper.

How long is an expository essay?

Target about 800 words for expository writing. It includes five paragraphs: an introduction, three body paragraphs, and a conclusion. Check your prompt carefully: It often mentions the number of words to write.

Over to You

I hope this article has answered your “What is an expository essay” question. Remember about the purpose: inform and educate readers. Imagine yourself as a lecturer who needs to tell the audience about the subject — and voila !

What Is Expository Writing?

How to Write an Expository Essay

• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

Expository writing is used to convey factual information (as opposed to creative writing, such as fiction). It is the language of learning and understanding the world around us. If you've ever read an encyclopedia entry, a how-to article on a website, or a chapter in a textbook, then you've encountered examples of expository writing.

Key Takeaways: Expository Writing

• Just the facts, M'am: Expository writing is informational, not creative writing.
• Anytime you write to describe or explain, you use expository writing.
• Use a logical flow when planning an expository essay, report, or article: introduction, body text, and conclusion.
• It's often easier to write the body of your article first, before composing the introduction or conclusion.

Expository writing is everywhere in everyday life, not just academic settings, as it's present anytime there's information to be conveyed. It can take form in an academic paper, an article for a newspaper, a report for a business, or even book-length nonfiction. It explains, informs, and describes.

Types of Expository Writing

In  composition studies , expository writing (also called exposition ) is one of the four traditional  modes of discourse . It may include elements of  narration ,  description , and  argumentation . Unlike creative or  persuasive writing , which can appeal to emotions and use anecdotes, expository writing's primary  purpose  is to deliver information about an issue, subject, method, or idea using facts.

Exposition may take one of several forms:

• Descriptive/definition:  In this style of writing, topics are defined by characteristics, traits, and examples. An encyclopedia entry is a kind of descriptive essay. 
• Process/sequential:  This essay outlines a series of steps needed in order to complete a task or produce something. A recipe at the end of an article in a food magazine is one example.
• Comparative/contrast:  This kind of exposition is used to demonstrate how two or more subjects are the same and different. An article that explains the difference between owning and renting a home and the benefits and drawbacks of each is one such an example.
• Cause/effect:  This kind of essay describes how one step leads to a result. An example is a personal blog chronicling a workout regimen and documenting the results over time.
• Problem/solution: This type of essay presents a problem and possible solutions, backed by data and facts, not just opinion.
• Classification: A classification essay breaks down a broad topic into categories or groupings.

Tips for Expository Writing

As you write, keep in mind some of these tips for creating an effective expository essay:

Start where you know the information best. You don't have to write your introduction first. In fact, it might be easier to wait until the end for that. If you don't like the look of a blank page, move over the slugs from your outline for the main body paragraphs and write the topic sentences for each. Then start putting in your information according to each paragraph's topic.

Be clear and concise.  Readers have a limited attention span. Make your case succinctly in language that the average reader can understand. 

Stick to the facts.  Although an exposition can be persuasive, it should not be based on opinion only. Support your case with facts, data, and reputable sources that can be documented and verified.

Consider voice and tone.  How you address the reader depends on the kind of essay you're writing. An essay written in the first person is fine for a personal travel essay but is inappropriate if you're a business reporter describing a patent lawsuit. Think about your audience before you begin writing.

Planning Your Essay

• Brainstorm: Jot down ideas on a blank piece of paper. Connect them with arrows and lines, or just make lists. Rigor doesn't matter at this stage. Bad ideas don't matter at this stage. Just write down ideas, and the engine in your head will lead you to a good one. When you've got that idea, then repeat the brainstorming exercise with ideas that you want to pursue on that topic and information you could put in. From this list, you'll start to see a path emerge for your research or narrative to follow.
• Compose your thesis: When your ideas coalesce into a sentence in which you can summarize the topic you're writing about, you're ready to compose your thesis sentence. Write down in one sentence the main idea that you'll explore in your paper.
• Examine your thesis: Is it clear? Does it contain opinion? If so, revise that out. For this type of essay, you stick to the facts and evidence. This isn't an editorial. Is the thesis' scope manageable? You don't want your topic too narrow or too broad to be covered in the amount of space you have for your paper. If it's not a manageable topic, refine it. Don't be dismayed if you have to come back and tweak it if your research finds that your initial idea was off-kilter. It's all just part of the process of focusing the material.
• Outline: It may seem inconsequential, but making even a quick outline can save you time by organizing your areas of pursuit and narrowing them down. When you see your topics in an organized list, you may be able to discard off-topic threads before you research them—or as you're researching them and you find they just don't work.
• Research: Find your data and sources to back up the areas you want to pursue to support your thesis statement. Look for sources written by experts, including organizations, and watch for bias. Possible sources include statistics, definitions, charts and graphs, and expert quotes and anecdotes. Compile descriptive details and comparisons to make your topic clear to your reader, when applicable.

What Is an Expository Essay?

An expository essay has three basic parts: the introduction, the body, and the conclusion. Each is crucial to writing a clear article or effective argument.

The introduction: The first paragraph is where you'll lay the foundation for your essay and give the reader an overview of your thesis. Use your opening sentence to get the reader's attention, and then follow up with a few sentences that give your reader some context for the information you're about to cover.

The body:  At a minimum, include three to five paragraphs in the body of your expository essay. The body could be considerably longer, depending on your topic and audience. Each paragraph begins with a topic sentence where you state your case or objective. Each topic sentence supports your overall thesis statement. Then, each paragraph includes several sentences that expand on the information and/or support the topic sentence. Finally, a concluding sentence offers a transition to the following paragraph in the essay.

The conclusion:  The final section of your expository essay should give the reader a concise overview of your thesis. The intent is not merely to summarize your argument but to use it as a means of proposing further action, offering a solution, or posing new questions to explore. Don't cover new material related to your thesis, though. This is where you wrap it all up.

Expository Examples

An expository article or report about a lake, for example, could discuss its ecosystem: the plants and animals that depend on it along with its climate. It could describe physical details about its size, depth, amount of rainfall each year, and the number of tourists it receives annually. Information on when it was formed, its best fishing spots, or its water quality could be included, depending on the audience for the piece.

An expository piece could be in third person or second person. Second-person examples could include, for example, how to test lake water for pollutants or how to kill invasive species. Expository writing is useful and informative.

In contrast, someone writing a creative nonfiction article about a lake might relate the place to a defining moment in his or her life, penning the piece in first person. It could be filled with emotion, opinion, sensory details, and even include dialogue and flashbacks. It's a much more evocative, personal type of writing than an expository piece, even though they're both nonfiction styles.

Expository Essay – In a Nutshell

An expository essay aims to provide a solution or explanation of a subject or issue at hand. Techniques in writing this type of essay can come in handy when a fact-based analysis is required in any field. Learn everything you need to know about writing an expository essay in this article:

• There are 4 types of expository essays: Descriptive essay, process essay , compare and contrast essay , and cause and effect essay .
• An expository essay includes 3 main sections : Introduction, body, and conclusion.
• Learn tips and tricks to consider when writing an expository essay

Definition: Expository essay

A style of academic writing known as an expository essay tries to clarify, observe, and describe a thought, problem, or notion. It entails looking into a theory, assessing the supporting data, outlining the theory, and then developing an argument based on the research.

Expository essays follow a format similar to other types of academic essays , such as persuasive essays or argumentative essays . The primary distinction is that the expository essay necessitates more investigation and factual information to substantiate the claim. Common examples of expository essays include a process, or how-to essay that provides instructions on how to accomplish a task, assembly instructions, and newspaper articles.

The purpose of an expository essay

An expository essay is written when the researcher intents to provide a solution or an explanation about a specific topic or issue. The primary purpose of such an essay is to explain or analyze a complex topic and is often used to explore complex or controversial issues. Mostly, these essays investigate an idea or subject, evaluate the evidence available, develop the idea, and provide an argument regarding that idea clearly and concisely.

Types of expository essays

There are four main types of expository essays:

Descriptive essay

A descriptive essay gives details on a particular person, place, thing, or experience. The author describes the topic with sensory information describing an individual, place, thing, or experience while giving in-depth information about the subject. Providing an intricate description of something or an event is the primary objective of such an essay.

Process essay

A process essay describes how to carry out a task or how something is supposed to take place. The author must ensure that the steps in the process are described in chronological order. A process essay’s primary goal is to give comprehensive directions on carrying out a task with minimal mistakes.

A beach description essay can discuss the sound of the waves lapping against the shore, the salty air, and the sensation of sand between the toes. Additionally, a person’s physical attributes, psychological traits, and interests could all be discussed in a descriptive essay about that individual.

A process essay on how to bake a cake might describe the processes involved, from combining the ingredients to placing the cake in the oven. Also, planting crops must follow a specific process lest they fail in their tracks.

Compare and contrast essay

A compare and contrast essay explains the differences and similarities between two or more individuals, things, places, or experiences. In a comparison essay, two objects are compared, and their similarities and differences are discussed. This essay’s primary goal is to make the reader understand the subjects under comparison.

Cause and effect

A cause and effect essay explains the reasons for something or the effects of something. This essay will discuss the causes of a problem or situation and its consequences. The main purpose of a cause-and-effect essay is to help the reader understand the reason behind a problem or situation.

In a compare and contrast essay about two nations, you might talk about how the two nations’ cultures, languages, and religions differ. Further, a compare and contrast essay on two books can discuss how the themes are similar but the character development differs.

An essay on obesity’s causes and effects can go over the factors contributing to the country’s rising obesity rates. Also, a cause and effect essay about the Vietnam War can go into the conflict’s origins and how it affected the Vietnamese people

Structuring an expository essay

The structure of this essay is similar to that of other essays, such as the five-paragraph essay.

The introduction:

Introduces the essay’s core idea while providing critical background information. Start your introduction with a catchy sentence to draw the reader in, such as rhetorical questions, quotations, anecdotes, concessions, intriguing facts, or questions that will be addressed in your body section. The thesis statement for a narrative essay has a slightly different function than an expository essay because the former can introduce the plot’s events.

A three-paragraph body is the standard format for such essays. The topic is introduced in the first paragraph, followed by complementary information in the second paragraph, and then the bottom-line section as the third body paragraph.

The conclusion:

An expository essay also has a conclusion, acting as the summary of the essay’s main points.

How to write an expository essay

The most efficient method to begin an essay is simply, to begin writing. Get your ideas down on paper first without worrying about grammar or spelling. Check it for grammatical and spelling issues when you’ve finished writing your essay.

Make sure your thoughts are concise, and your essay flows naturally while editing. Read your writing aloud as a means to verify this. If you become lost or confused while reading your work, this is a good indicator that you have probably not adequately ordered your work.

What Is an Expository Essay?

An essay that explains a writer’s ideas by defining, explaining, informing, or elaborating on points to allow the reader to clearly understand the concept.

Many of your future academic workplace writing assignments will be expository–explaining your ideas or the significance of a concept or action. An expository essay allows the writer the opportunity to explain his or her ideas about a topic and to provide clarity for the reader by using:

• Explanations
• Definitions

It may also include the writer outlining steps of a procedure in a way that is straightforward for the reader to follow. It is purely informative and often contains elements of summary.

Imagine you need to verbally explain a concept to your classmates, maybe a behavioural theory. What are the key elements on which you would focus? How would you organize the information? You could explain who came up with the theory, the specific area of study to which it is related, its purpose, and the significant details to explain the theory. Telling these four elements to your classmates would give them a complete, yet summarized, picture of the theory, so they could apply the theory in future discussions.

Although you did this verbally, you were still fulfilling the elements of an expository essay by providing definition, details, explanations, and maybe even facts if you have a really good memory. This is the same process that you would use when you write an expository essay. You may actually be doing this all the time; for example, when you are giving someone directions to a place or explaining how to cook something. In the following sections of the chapter, you will practise doing this more in different expository written forms.

The Structure of an Expository Essay

Sections versus paragraphs.

Before looking at the general structure of an expository essay, you first need to know that in your post-secondary education, you should not consider your essay as writing being constructed with five paragraphs as you might have been used to in high school. You should instead think of your essay in terms of sections (there may be five), and each section may have multiple paragraphs.

To understand further why you need to think beyond the five-paragraph essay, imagine you have been asked to submit a six-page paper (approximately 1,500 words). You already know that each paragraph should be roughly 75 to 200 words long. If you divide the required word count by five paragraphs (1,500 by 5), you end with 300 words per paragraph, way above the number you should have in a paragraph. If your paragraphs are too long, they likely have too many ideas and your reader may become confused. Your paragraphs should be two-third of a page at most, and never longer than a page.

Instead, if you think of your essays being divided into sections (with possibly more than one paragraph per section), your writing will likely be more organized and allow your reader to follow your presentation of ideas without creating too much distance between your paragraph’s supporting points and its topic sentence.

As you will see in Section 4.5, some essay forms may require even more than five paragraphs or sections because of how many points are necessary to address. For the rest of this chapter, the term paragraph will also imply section.

Sections of an Expository Essay

An expository essay, regardless of its purpose, should have at least five sections, which are:

• Introduction
• First body section/paragraph
• Second body section/paragraph
• Third body section/paragraph
• Conclusion.

The introduction should state the topic of your paper: your thesis statement as well as brief signposts of what information the rest of the paper will include. That is, you only want to mention the content of the body paragraphs; you do not want to go in to a lot of detail and repeat what will be in the rest of the essay.

The first body section or paragraph should focus on one of your main points and provide evidence to support that point. There should be two to three supporting points: reasons, facts, statistics, quotations, examples, or a mix of these. Both the second and third body sections should follow the same pattern. Providing three body sections with one point each that supports the thesis should provide the reader with enough detail to be convinced of your argument or fully understand the concept you are explaining. However, remember that some sections will require more explanation, and you may need to separate this information into multiple paragraphs.

You can order your sections in the most logical way to explain your ideas. For example, if you are describing a process, you may use chronological order to show the definite time order in which the steps need to happen. You will learn about the different ways to organize your body paragraphs in the next chapter.

The concluding paragraph , or conclusion, can be a little tricky to compose because you need to make sure you give a concise summary of the body paragraphs, but you must be careful not to simply repeat what you have already written. Look back at the main idea of each section/paragraph, and try to summarize the point using words different from those you have already used. Do not include any new points in your concluding paragraph.

Consider Your Audience: How Much Do They Know?

Later in this chapter, you will work on determining and adapting to your audience when writing, but with an expository essay, since you are defining or informing your audience on a certain topic, you need to evaluate how much your audience knows about that topic (aside from having general common knowledge). You want to make sure you are giving thorough, comprehensive, and clear explanations on the topic. Never assume the reader knows everything about your topic (even if it is covered in the reader’s field of study). For example, even though some of your instructors may teach criminology, they may have specialized in different areas from the one about which you are writing; they most likely have a strong understanding of the concepts but may not recall all the small details on the topic. If your instructor specialized in crime mapping and data analysis for example, he or she may not have a strong recollection of specific criminological theories related to other areas of study. Providing enough background information without being too detailed is a fine balance, but you always want to ensure you have no gaps in the information, so your reader will not have to guess your intention. Again, we will practise this more in Section 4.9.

What Comes Next?

In the next eight sections (4.2 through 4.9), we will look at different expository modes, or rhetorical modes, you will often be assigned. These are:

• Illustration
• Description
• Classification
• Process analysis
• Compare and contrast
• Cause and effect

Rhetorical modes refers simply to the ways to communicate effectively through language. As you read about these modes, keep in mind that the rhetorical mode a writer chooses depends on his or her purpose for writing. Sometimes writers incorporate a variety of modes in any one essay. In this chapter, we also emphasize the rhetorical modes as a set of tools that will allow you greater flexibility and effectiveness in communicating with your audience and expressing your ideas.

In a few weeks, you will need to submit your first essay–an expository sample–and you will be given the choice of topic: one from each of the modes. Think about which types of expository essays are easier and which are more challenging for you. As mentioned, as you progress through your studies, you will be exposed to each of these types. You may want to explore a mode you find more challenging than the others in order to ensure you have a full grasp on developing each type. However, it is up to you. As you work through the sections, think about possible topics you may like to cover in your expository essay and start brainstorming as you work through the self-practice exercises.

After we explore each of the individual modes in the eight sections that follow, we will look at outlining and drafting; it is at this point you will want to fine tune and narrow the topic you will write about, so you can focus on that when doing the exercises.

Expository Writing Definition

Expository writing is a genre of writing that is used to explain, describe, inform, or clarify a particular expository essay topic to the reader. 

Unlike other forms of writing that may involve personal opinions or persuasion, the characteristics of expository writing include a focus on providing factual information in a clear and organized manner.

Expository essay writing is a very common form of writing; journals, newspaper articles, and essays usually demonstrate this type of writing.

While writing an expository essay, you need to explain everything in detail to make the idea clear for the reader. You can take help from  expository essay examples  to see what elements make a perfect expository essay.

What are the Types of Expository Writing?

There are 10 types of expository essay writing, including:

• Compare and Contrast Essay 

Cause and Effect Essay

• Problem and Solution Essay 

Process Essay

Definition essay.

• Classification Essay 
• Descriptive Writing
• Exploratory Writing
• Anecdotal Evidence
• Sequential Writing

Let’s take a look at common types of expository writing one by one.

Compare and Contrast Essay

The  compare and contrast essay  is a type of essay in which the writer compares and contrasts two things. The writer compares the similarities between the two selected subjects and contrasts the differences in those subjects. The subjects should belong to the same category.

In the  cause and effect essay , the writer tries to find the cause of something; why did something happen? and what effects it might have. This type of essay has built around the reason that caused something to happen and its possible impacts.

There are two ways to structure a cause and effect essay:

• Block structure:  All the causes are presented first, and then all of their effects.
• Chain structure:  Each of the causes is followed by its effect straight away.

This essay could be based on assumptions or could be based on facts, but either way, they should be validated.

Problem and Solution Essay

In the  problem solution essay , the writer identifies a problem and then proposes its solution. The writer examines the particular subject from various aspects and perspectives prior to providing a solution. This essay is somewhat similar to the cause and effect essay.

The process essay refers to the process of something, i.e., how to make an apple pie. This type of writing includes a step-by-step process of making or doing something.

This is how you write a process essay; it provides the complete process of doing something. The goal is to provide the process in such a way that the reader can follow the sequence without any mistakes.

The  definition essay  is a type of expository essay that gives a complete description of the topic. It explains what the term or the topic of the essay exactly means. Some terms have concrete meanings like glass, book, etc. Whereas some have abstract meanings like love, respect, honor, etc.

The definition essay revolves around explaining the purpose, what, why, and how aspects of the topic of the essay. This essay could start with the dictionary definition and ultimately provide the extended definition.

Classification Essay

Classification essays are a type of expository writing that categorizes and organizes objects, people, ideas, or concepts into distinct groups based on shared characteristics, features, or criteria. The goal is to help readers better understand the relationships and differences between these categories. 

Descriptive Writing 

Descriptive writing is a type of expository writing that aims to paint a vivid picture of a person, place, object, event, or concept in the reader's mind. It uses sensory details and vivid language to create a sensory experience for the audience. 

Exploratory Writing 

Exploratory writing aims to investigate a topic or question from multiple angles, often without taking a definitive stance. It allows the writer and reader to explore various viewpoints and ideas. 

Anecdotal Evidence 

Anecdotal evidence refers to personal stories, individual accounts, or isolated examples that are used to support a claim or argument. While anecdotal evidence can be compelling and relatable, it is based on personal experiences and may not reflect broader trends or realities. 

Sequential Writing 

Sequential writing, also known as chronological writing, involves organising information or events in a clear, time-based order. This approach is often used when presenting a series of actions, or events in a logical sequence, making it easier for readers to understand a process.
