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 argumentative essay?
The argumentative essay is a genre of writing that requires the student to investigate a topic; collect, generate, and evaluate evidence; and establish a position on the topic in a concise manner.
Please note: Some confusion may occur between the argumentative essay and the expository essay. These two genres are similar, but the argumentative essay differs from the expository essay in the amount of pre-writing (invention) and research involved. The argumentative essay is commonly assigned as a capstone or final project in first year writing or advanced composition courses and involves lengthy, detailed research. Expository essays involve less research and are shorter in length. Expository essays are often used for in-class writing exercises or tests, such as the GED or GRE.
Argumentative essay assignments generally call for extensive research of literature or previously published material. Argumentative assignments may also require empirical research where the student collects data through interviews, surveys, observations, or experiments. Detailed research allows the student to learn about the topic and to understand different points of view regarding the topic so that she/he may choose a position and support it with the evidence collected during research. Regardless of the amount or type of research involved, argumentative essays must establish a clear thesis and follow sound reasoning.
The structure of the argumentative essay is held together by the following.
- A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.
In the first paragraph of an argument essay, students should set the context by reviewing the topic in a general way. Next the author should explain why the topic is important (exigence) or why readers should care about the issue. Lastly, students should present the thesis statement. 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. Transitions should wrap up the idea from the previous section and introduce the idea that is to follow in the next section.
- Body paragraphs that include evidential support.
Each paragraph should be limited to the discussion of one general idea. This will allow for clarity and direction throughout the essay. In addition, 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. Some paragraphs will directly support the thesis statement with evidence collected during research. It is also important to explain how and why the evidence supports the thesis (warrant).
However, argumentative essays should also consider and explain differing points of view regarding the topic. Depending on the length of the assignment, students should dedicate one or two paragraphs of an argumentative essay to discussing conflicting opinions on the topic. Rather than explaining how these differing opinions are wrong outright, students should note how opinions that do not align with their thesis might not be well informed or how they might be out of date.
- Evidential support (whether factual, logical, statistical, or anecdotal).
The argumentative essay requires well-researched, accurate, detailed, and current information to support the thesis statement and consider other points of view. Some factual, logical, statistical, or anecdotal evidence should support the thesis. However, students must consider multiple points of view when collecting evidence. As noted in the paragraph above, a successful and well-rounded argumentative essay will also discuss opinions not aligning with the thesis. It is unethical to exclude evidence that may not support the thesis. It is not the student’s job to point out how other positions are wrong outright, but rather to explain how other positions may not be well informed or up to date on the topic.
- 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 may 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 the information presented in the body of the essay. Restate why the topic is important, review the main points, and review your thesis. You may also want to include a short discussion of more research that should be completed in light of your work.
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 World War II 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 argument in the middle of my second point, questions would arise concerning the current effects on those who lived through the conflict. Therefore, the argumentative 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 argumentative 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 (a) an introductory paragraph (b) three evidentiary body paragraphs that may include discussion of opposing views and (c) a conclusion.
Longer argumentative essays
Complex issues and detailed research call for complex and detailed essays. Argumentative essays discussing a number of research sources or empirical research will most certainly be longer than five paragraphs. Authors may have to discuss the context surrounding the topic, sources of information and their credibility, as well as a number of different opinions on the issue before concluding the essay. Many of these factors will be determined by the assignment.
|A classic format for compositions is the five-paragraph essay. It is not the only format for writing an essay, of course, but it is a useful model for you to keep in mind, especially as you begin to develop your composition skills. The following material is adapted from a handout prepared by Harry Livermore for his high school English classes at Cook High School in Adel, Georgia. It is used here with his permission.|
See, first, Writing Introductory Paragraphs for different ways of getting your reader involved in your essay. The introductory paragraph should also include the thesis statement, a kind of mini-outline for the paper: it tells the reader what the essay is about. The last sentence of this paragraph must also contain a transitional "hook" which moves the reader to the first paragraph of the body of the paper.
Body First paragraph:
The first paragraph of the body should contain the strongest argument, most significant example, cleverest illustration, or an obvious beginning point. The first sentence of this paragraph should include the "reverse hook" which ties in with the transitional hook at the end of the introductory paragraph. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional hook to tie into the second paragraph of the body.
Body Second paragraph:
The second paragraph of the body should contain the second strongest argument, second most significant example, second cleverest illustration, or an obvious follow up the first paragraph in the body. The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the first paragraph of the body. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional hook to tie into the third paragraph of the body.
Body Third paragraph:
The third paragraph of the body should contain the weakest argument, weakest example, weakest illustration, or an obvious follow up to the second paragraph in the body. The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the second paragraph. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional concluding hook that signals the reader that this is the final major point being made in this paper. This hook also leads into the last, or concluding, paragraph.
This paragraph should include the following:
- an allusion to the pattern used in the introductory paragraph,
- a restatement of the thesis statement, using some of the original language or language that "echoes" the original language. (The restatement, however, must not be a duplicate thesis statement.)
- a summary of the three main points from the body of the paper.
- a final statement that gives the reader signals that the discussion has come to an end. (This final statement may be a "call to action" in an persuasive paper.)
A Sample Paper
|1Stephen King, creator of such stories as Carrie and Pet Sematary, stated that the Edgar Allan Poe stories he read as a child gave him the inspiration and instruction he needed to become the writer that he is. 2Poe, as does Stephen King, fills the reader's imagination with the images that he wishes the reader to see, hear, and feel. 3His use of vivid, concrete visual imagery to present both static and dynamic settings and to describe people is part of his technique. 4Poe's short story "The Tell-Tale Heart" is a story about a young man who kills an old man who cares for him, dismembers the corpse, then goes mad when he thinks he hears the old man's heart beating beneath the floor boards under his feet as he sits and discusses the old man's absence with the police. 5In "The Tell-Tale Heart," a careful reader can observe Poe's skillful manipulation of the senses.||The introductory paragraph includes a paraphrase of something said by a famous person in order to get the reader's attention. The second sentence leads up to the thesis statement which is the third sentence. The thesis statement (sentence 3) presents topic of the paper to the reader and provides a mini- outline. The topic is Poe's use of visual imagery. The mini- outline tells the reader that this paper will present Poe's use of imagery in three places in his writing: (1) description of static setting; (2) description of dynamic setting; and (3) description of a person. The last sentence of the paragraph uses the words "manipulation" and "senses" as transitional hooks.|
|1The sense of sight, the primary sense, is particularly susceptible to manipulation. 2In "The Tell-Tale Heart," Poe uses the following image to describe a static scene: "His room was as black as pitch with the thick darkness . . ." Poe used the words "black," "pitch," and "thick darkness" not only to show the reader the condition of the old man's room, but also to make the reader feel the darkness." 3"Thick" is a word that is not usually associated with color (darkness), yet in using it, Poe stimulates the reader's sense of feeling as well as his sense of sight.||In the first sentence of the second paragraph (first paragraph of the body) the words "sense" and "manipulation" are used to hook into the end of the introductory paragraph. The first part of the second sentence provides the topic for this paragraph--imagery in a static scene. Then a quotation from "The Tell-Tale Heart" is presented and briefly discussed. The last sentence of this paragraph uses the expressions "sense of feeling" and "sense of sight" as hooks for leading into the third paragraph.|
|1Further on in the story, Poe uses a couple of words that cross not only the sense of sight but also the sense of feeling to describe a dynamic scene. 2The youth in the story has been standing in the open doorway of the old man's room for a long time, waiting for just the right moment to reveal himself to the old man in order to frighten him. 3Poe writes: "So I opened it [the lantern opening]--you cannot imagine how stealthily, stealthily--until, at length, a single dim ray, like the thread of the spider, shot from out the crevice and fell full upon the vulture eye." 4By using the metaphor of the thread of the spider (which we all know is a creepy creature) and the word "shot," Poe almost makes the reader gasp, as surely did the old man whose one blind eye the young man describes as "the vulture eye."||The first sentence of the third paragraph (second paragraph of the body) uses the words "sense of sight" and "sense of feeling" to hook back into the previous paragraph. Note that in the second paragraph "feeling" came first, and in this paragraph "sight" comes first. The first sentence also includes the topic for this paragraph--imagery in a dynamic scene. Again, a quotation is taken from the story, and it is briefly discussed. The last sentence uses the words "one blind eye" which was in the quotation. This expression provides the transitional hook for the last paragraph in the body of the paper.|
|1The reader does not know much about what the old man in this story looks like except that he has one blind eye. 2In the second paragraph of "The Tell-Tale Heart," Poe establishes the young man's obsession with that blind eye when he writes: "He had the eye of the vulture--a pale blue eye, with a film over it." 3This "vulture eye" is evoked over and over again in the story until the reader becomes as obsessed with it as does the young man. 4His use of the vivid, concrete word "vulture" establishes a specific image in the mind of the reader that is inescapable.||In the first sentence of the fourth paragraph (third paragraph in the body), "one blind eye" is used that hooks into the previous paragraph. This first sentence also lets the reader know that this paragraph will deal with descriptions of people: ". . . what the old man looks like . . .." Once again Poe is quoted and discussed. The last sentence uses the word "image" which hooks into the last paragraph. (It is less important that this paragraph has a hook since the last paragraph is going to include a summary of the body of the paper.)|
|1"Thick darkness," "thread of the spider," and "vulture eye" are three images that Poe used in "The Tell-Tale Heart" to stimulate a reader's senses. 2Poe wanted the reader to see and feel real life. 3He used concrete imagery rather than vague abstract words to describe settings and people. 4If Edgar Allan Poe was one of Stephen King's teachers, then readers of King owe a debt of gratitude to that nineteenth-century creator of horror stories.||The first sentence of the concluding paragraph uses the principal words from the quotations from each paragraph of the body of the paper. This summarizes those three paragraph. The second and third sentences provide observations which can also be considered a summary, not only of the content of the paper, but also offers personal opinion which was logically drawn as the result of this study. The last sentence returns to the Edgar Allan Poe-Stephen King relationship which began this paper. This sentence also provides a "wrap-up" and gives the paper a sense of finality.|
