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: Everything You Need to Know
Expository writing, as its name implies, is writing that exposes facts. In other words, it’s writing that explains and educates its readers, rather than entertaining or attempting to persuade them. When you read a scholarly article, a textbook page, a news report, or an instructional guide, you’re reading expository writing.

What is expository writing?
Expository writing is writing that aims to inform its reader. As we mentioned above, this includes all types of factual writing, like textbooks, news stories, technical guides, and pieces of business writing. Many journalistic pieces are pieces of expository writing, but not all are—advertorials, opinion pieces, and many pieces of political writing are not pieces of expository writing because their primary goal is something other than providing unbiased facts.
An easy way to understand expository writing is to compare and contrast it with other types of writing . Three other commonly recognized types of writing are descriptive , narrative , and persuasive . Each of these types of writing has a specific goal. Descriptive writing creates a sense of time, place, and experience in the reader’s mind. Narrative writing tells the reader a story. Persuasive writing convinces the reader that a specific position is the right position. Expository writing gives the reader the facts they need about a specific topic to deepen their understanding of it.
Expository writing is:
- Usually presented in a linear format
- Always presented in a logical format
- Clear about its purpose
Expository writing is not:
- The author’s opinion
- An attempt to change the reader’s mind or shape their perspective
- Nonlinear or otherwise unconventional in how it presents content
Expository writing can still be fun and engaging
Although expository writing is fact-based, it doesn’t need to be dry or boring. Skilled writing can present factual information in an engaging way that only increases the reader’s comprehension of the topic, often by borrowing techniques used in narrative and descriptive writing to make the facts more vivid and impactful. If you’ve ever seen the docuseries Cosmos , you’ve seen engaging expository writing in action. In both the 1980 and 2014 versions, the host captivates viewers by guiding them through our known universe, our solar system, and how life on Earth evolved over millennia. Although Cosmos is a docuseries, the narrative that speaks directly to the viewer and constantly positions them within our universe’s story is a kind of expository writing: screenwriting.
However, discerning an expository piece’s credibility can be tricky at times. Remember one of the kinds of writing we mentioned above, advertorials? An advertorial is an advertisement disguised as an editorial. In other words, it’s an article presented as either fact or the author’s personal thoughts, but really, it’s a sponsored advertisement. Advertorials aren’t the only instance where you can find subjective opinions disguised as objective facts—many documentaries, journalistic pieces, books, and even scholarly articles are written according to the author’s bias or to fit a specific agenda.
This is why it’s so critical to carefully vet every source you use when you’re working on an expository writing assignment. Inadvertently using a biased source in your academic writing can undermine your work by making it look like you either didn’t research the topic carefully or are pushing a specific agenda in your writing.
Types of expository writing
There are numerous ways to present topics in a piece of expository writing:
- Compare and contrast . In a compare-and-contrast essay , you present two or more subjects and write about their similarities and differences.
- Definition. This type of expository writing defines a subject. For example, you might write a piece that defines a historic figure by exploring their actions, motivations, and circumstances.
- Classification. In a classification piece, you write about the characteristics of multiple subjects within one category. For example, you might write a blog post about the types of expository writing. In that blog post, you explain each type of expository writing, covering their differences as well as their similarities.
- Problem and solution. In a problem and solution piece, you explain an existing problem and then explore the most effective solution for that problem. This kind of structure can also be found in persuasive writing, but when it’s used in expository writing, it’s generally used in troubleshooting guides and to explain how specific problems have been solved.
- Process. When you need to explain how a process works or the steps the reader needs to follow to assemble something or complete another task, you write out the process step by step, providing as much explanation as necessary for each step.
Just like the other commonly recognized writing styles , you’ll find lots of drastically different expository writing examples. Technical manuals and research papers are both types of expository writing. So are lab reports, investigative journalism pieces, expository essays, and explainer video scripts. Even recipes count as pieces of expository writing, as do travel guides and biographies.
How to do expository writing effectively
As a student, many of your writing assignments are pieces of expository writing. Presenting facts in a logical, clear way is a much different task from writing a fictional story or supporting your opinion. Here are a few tips to keep in mind when you’re completing expository writing assignments:
Work through the entire writing process
The first step in writing a strong piece isn’t typing words on a screen, but rather brainstorming your topic. With other kinds of writing, like narrative or persuasive writing, you might have a clear idea of what you want to write from the moment you receive your assignment and, with it, skip ahead a few steps in the writing process . But because you’re working with facts and a strategy for presenting them in a coherent, engaging way, you’ll need to devote time to thoroughly brainstorming, researching, outlining, and then drafting your work.
Be creative, but constrained
There’s room to have a little fun in your expository writing, but it’s not going to be a party on the page. Use literary devices like similes and juxtaposition sparingly and only when they serve to make the facts clearer to your reader.
Always check the facts
Expository writing is all about the facts. When you’re researching, you might come across contradictory sources. If this happens, examine the conflicting information to find the truth. You can do this by researching that specific piece of information and finding what other scholarly sources have to say about it and by examining who published the two conflicting sources. If one is a personal blog and the other is an article from a .edu or .gov website, the latter is more likely to be unbiased.
Share the facts with style
Expository writing is logical and fact-based, but it doesn’t have to be boring. In fact, it shouldn’t be. But it’s not always easy to present facts and figures in an engaging style.
Grammarly can help. Our writing suggestions ensure you’re using engaging vocabulary and that your sentences flow clearly. In addition, with Grammarly’s tone detector, you can instantly see how your writing is communicating with its reader: confident, friendly, direct, and casual are just a few of the tones Grammarly can pick up.

The Four Main Types of Essay | Quick Guide with Examples
Published on September 4, 2020 by Jack Caulfield . Revised on December 6, 2021.
An essay is a focused piece of writing designed to inform or persuade. There are many different types of essay, but they are often defined in four categories: argumentative, expository, narrative, and descriptive essays.
Argumentative and expository essays are focused on conveying information and making clear points, while narrative and descriptive essays are about exercising creativity and writing in an interesting way. At university level, argumentative essays are the most common type.
In high school and college, you will also often have to write textual analysis essays, which test your skills in close reading and interpretation.
Table of contents
Argumentative essays, expository essays, narrative essays, descriptive essays, textual analysis essays, frequently asked questions about types of essays.
An argumentative essay presents an extended, evidence-based argument. It requires a strong thesis statement —a clearly defined stance on your topic. Your aim is to convince the reader of your thesis using evidence (such as quotations ) and analysis.
Argumentative essays test your ability to research and present your own position on a topic. This is the most common type of essay at college level—most papers you write will involve some kind of argumentation.
The essay is divided into an introduction, body, and conclusion:
- The introduction provides your topic and thesis statement
- The body presents your evidence and arguments
- The conclusion summarizes your argument and emphasizes its importance
The example below is a paragraph from the body of an argumentative essay about the effects of the internet on education. Mouse over it to learn more.
A common frustration for teachers is students’ use of Wikipedia as a source in their writing. Its prevalence among students is not exaggerated; a survey found that the vast majority of the students surveyed used Wikipedia (Head & Eisenberg, 2010). An article in The Guardian stresses a common objection to its use: “a reliance on Wikipedia can discourage students from engaging with genuine academic writing” (Coomer, 2013). Teachers are clearly not mistaken in viewing Wikipedia usage as ubiquitous among their students; but the claim that it discourages engagement with academic sources requires further investigation. This point is treated as self-evident by many teachers, but Wikipedia itself explicitly encourages students to look into other sources. Its articles often provide references to academic publications and include warning notes where citations are missing; the site’s own guidelines for research make clear that it should be used as a starting point, emphasizing that users should always “read the references and check whether they really do support what the article says” (“Wikipedia:Researching with Wikipedia,” 2020). Indeed, for many students, Wikipedia is their first encounter with the concepts of citation and referencing. The use of Wikipedia therefore has a positive side that merits deeper consideration than it often receives.
An expository essay provides a clear, focused explanation of a topic. It doesn’t require an original argument, just a balanced and well-organized view of the topic.
Expository essays test your familiarity with a topic and your ability to organize and convey information. They are commonly assigned at high school or in exam questions at college level.
The introduction of an expository essay states your topic and provides some general background, the body presents the details, and the conclusion summarizes the information presented.
A typical body paragraph from an expository essay about the invention of the printing press is shown below. Mouse over it to learn more.
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.

A narrative essay is one that tells a story. This is usually a story about a personal experience you had, but it may also be an imaginative exploration of something you have not experienced.
Narrative essays test your ability to build up a narrative in an engaging, well-structured way. They are much more personal and creative than other kinds of academic writing . Writing a personal statement for an application requires the same skills as a narrative essay.
A narrative essay isn’t strictly divided into introduction, body, and conclusion, but it should still begin by setting up the narrative and finish by expressing the point of the story—what you learned from your experience, or why it made an impression on you.
Mouse over the example below, a short narrative essay responding to the prompt “Write about an experience where you learned something about yourself,” to explore its structure.
Since elementary school, I have always favored subjects like science and math over the humanities. My instinct was always to think of these subjects as more solid and serious than classes like English. If there was no right answer, I thought, why bother? But recently I had an experience that taught me my academic interests are more flexible than I had thought: I took my first philosophy class.
Before I entered the classroom, I was skeptical. I waited outside with the other students and wondered what exactly philosophy would involve—I really had no idea. I imagined something pretty abstract: long, stilted conversations pondering the meaning of life. But what I got was something quite different.
A young man in jeans, Mr. Jones—“but you can call me Rob”—was far from the white-haired, buttoned-up old man I had half-expected. And rather than pulling us into pedantic arguments about obscure philosophical points, Rob engaged us on our level. To talk free will, we looked at our own choices. To talk ethics, we looked at dilemmas we had faced ourselves. By the end of class, I’d discovered that questions with no right answer can turn out to be the most interesting ones.
The experience has taught me to look at things a little more “philosophically”—and not just because it was a philosophy class! I learned that if I let go of my preconceptions, I can actually get a lot out of subjects I was previously dismissive of. The class taught me—in more ways than one—to look at things with an open mind.
A descriptive essay provides a detailed sensory description of something. Like narrative essays, they allow you to be more creative than most academic writing, but they are more tightly focused than narrative essays. You might describe a specific place or object, rather than telling a whole story.
Descriptive essays test your ability to use language creatively, making striking word choices to convey a memorable picture of what you’re describing.
A descriptive essay can be quite loosely structured, though it should usually begin by introducing the object of your description and end by drawing an overall picture of it. The important thing is to use careful word choices and figurative language to create an original description of your object.
Mouse over the example below, a response to the prompt “Describe a place you love to spend time in,” to learn more about descriptive essays.
On Sunday afternoons I like to spend my time in the garden behind my house. The garden is narrow but long, a corridor of green extending from the back of the house, and I sit on a lawn chair at the far end to read and relax. I am in my small peaceful paradise: the shade of the tree, the feel of the grass on my feet, the gentle activity of the fish in the pond beside me.
My cat crosses the garden nimbly and leaps onto the fence to survey it from above. From his perch he can watch over his little kingdom and keep an eye on the neighbours. He does this until the barking of next door’s dog scares him from his post and he bolts for the cat flap to govern from the safety of the kitchen.
With that, I am left alone with the fish, whose whole world is the pond by my feet. The fish explore the pond every day as if for the first time, prodding and inspecting every stone. I sometimes feel the same about sitting here in the garden; I know the place better than anyone, but whenever I return I still feel compelled to pay attention to all its details and novelties—a new bird perched in the tree, the growth of the grass, and the movement of the insects it shelters…
Sitting out in the garden, I feel serene. I feel at home. And yet I always feel there is more to discover. The bounds of my garden may be small, but there is a whole world contained within it, and it is one I will never get tired of inhabiting.
Though every essay type tests your writing skills, some essays also test your ability to read carefully and critically. In a textual analysis essay, you don’t just present information on a topic, but closely analyze a text to explain how it achieves certain effects.
Rhetorical analysis
A rhetorical analysis looks at a persuasive text (e.g. a speech, an essay, a political cartoon) in terms of the rhetorical devices it uses, and evaluates their effectiveness.
The goal is not to state whether you agree with the author’s argument but to look at how they have constructed it.
The introduction of a rhetorical analysis presents the text, some background information, and your thesis statement; the body comprises the analysis itself; and the conclusion wraps up your analysis of the text, emphasizing its relevance to broader concerns.
The example below is from a rhetorical analysis of Martin Luther King Jr.’s “I Have a Dream” speech . Mouse over it to learn more.
King’s speech is infused with prophetic language throughout. Even before the famous “dream” part of the speech, King’s language consistently strikes a prophetic tone. He refers to the Lincoln Memorial as a “hallowed spot” and speaks of rising “from the dark and desolate valley of segregation” to “make justice a reality for all of God’s children.” The assumption of this prophetic voice constitutes the text’s strongest ethical appeal; after linking himself with political figures like Lincoln and the Founding Fathers, King’s ethos adopts a distinctly religious tone, recalling Biblical prophets and preachers of change from across history. This adds significant force to his words; standing before an audience of hundreds of thousands, he states not just what the future should be, but what it will be: “The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.” This warning is almost apocalyptic in tone, though it concludes with the positive image of the “bright day of justice.” The power of King’s rhetoric thus stems not only from the pathos of his vision of a brighter future, but from the ethos of the prophetic voice he adopts in expressing this vision.
Literary analysis
A literary analysis essay presents a close reading of a work of literature—e.g. a poem or novel—to explore the choices made by the author and how they help to convey the text’s theme. It is not simply a book report or a review, but an in-depth interpretation of the text.
Literary analysis looks at things like setting, characters, themes, and figurative language. The goal is to closely analyze what the author conveys and how.
The introduction of a literary analysis essay presents the text and background, and provides your thesis statement; the body consists of close readings of the text with quotations and analysis in support of your argument; and the conclusion emphasizes what your approach tells us about the text.
Mouse over the example below, the introduction to a literary analysis essay on Frankenstein , to learn more.
Mary Shelley’s Frankenstein is often read as a crude cautionary tale about the dangers of scientific advancement unrestrained by ethical considerations. In this reading, protagonist Victor Frankenstein is a stable representation of the callous ambition of modern science throughout the novel. This essay, however, argues that far from providing a stable image of the character, Shelley uses shifting narrative perspectives to portray Frankenstein in an increasingly negative light as the novel goes on. While he initially appears to be a naive but sympathetic idealist, after the creature’s narrative Frankenstein begins to resemble—even in his own telling—the thoughtlessly cruel figure the creature represents him as. This essay begins by exploring the positive portrayal of Frankenstein in the first volume, then moves on to the creature’s perception of him, and finally discusses the third volume’s narrative shift toward viewing Frankenstein as the creature views him.
At high school and in composition classes at university, you’ll often be told to write a specific type of essay , but you might also just be given prompts.
Look for keywords in these prompts that suggest a certain approach: The word “explain” suggests you should write an expository essay , while the word “describe” implies a descriptive essay . An argumentative essay might be prompted with the word “assess” or “argue.”
The vast majority of essays written at university are some sort of argumentative essay . Almost all academic writing involves building up an argument, though other types of essay might be assigned in composition classes.
Essays can present arguments about all kinds of different topics. For example:
- In a literary analysis essay, you might make an argument for a specific interpretation of a text
- In a history essay, you might present an argument for the importance of a particular event
- In a politics essay, you might argue for the validity of a certain political theory
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.
The key difference is that a narrative essay is designed to tell a complete story, while a descriptive essay is meant to convey an intense description of a particular place, object, or concept.
Narrative and descriptive essays both allow you to write more personally and creatively than other kinds of essays , and similar writing skills can apply to both.

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
Difference between an expository essay and an argumentative essay, 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.”
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.”
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.”

An expository essay is an essay that communicates factual information. Broadly, this type of writing is known as expository writing . Expository essays rely on different structures to communicate their positions, like compare and contrast, process essays, and analyzing cause and effect.
