How to write an argumentative essay
An argumentative essay expresses an extended argument for a particular thesis statement. The author takes a clearly defined stance on their subject and builds up an evidence-based case for it.
Argumentative essays are by far the most common type of essay to write at university.
When do you write an argumentative essay?
You might be assigned an argumentative essay as a writing exercise in high school or in a composition class. The prompt will often ask you to argue for one of two positions, and may include terms like “argue” or “argument.” It will frequently take the form of a question.
The prompt may also be more open-ended in terms of the possible arguments you could make.
Argumentative writing at college level
At university, the vast majority of essays or papers you write will involve some form of argumentation.
In this context, you won’t necessarily be told to write an argumentative essay—but making an evidence-based argument is an essential goal of most academic writing, and this should be your default approach unless you’re told otherwise.
Examples of argumentative essay prompts
At a university level, all the prompts below imply an argumentative essay as the appropriate response.
Your research should lead you to develop a specific position on the topic. The essay then argues for that position and aims to convince the reader by presenting your evidence, evaluation and analysis.
Approaches to argumentative essays
An argumentative essay should be objective in its approach; your arguments should rely on logic and evidence, not on exaggeration or appeals to emotion.
There are many possible approaches to argumentative essays, but there are two common models that can help you start structuring your arguments: The Toulmin model and the Rogerian model.
The Toulmin model consists of four steps, which may be repeated as many times as necessary for the argument:
- Make a claim
- Provide the grounds (evidence) for the claim
- Explain the warrant (how the grounds support the claim)
- Discuss possible rebuttals to the claim, identifying the limits of the argument and showing that you have considered alternative perspectives
The Toulmin model is a common approach in academic essays. You don’t have to use these specific terms (grounds, warrants, rebuttals), but establishing a clear connection between your claims and the evidence supporting them is crucial in an argumentative essay.
Say you’re making an argument about the effectiveness of workplace anti-discrimination measures. You might:
- Claim that unconscious bias training does not have the desired results, and resources would be better spent on other approaches
- Cite data to support your claim
- Explain how the data indicates that the method is ineffective
- Anticipate objections to your claim based on other data, indicating whether these objections are valid, and if not, why not.
The Rogerian model also consists of four steps you might repeat throughout your essay:
- Discuss what the opposing position gets right and why people might hold this position
- Highlight the problems with this position
- Present your own position, showing how it addresses these problems
- Suggest a possible compromise—what elements of your position would proponents of the opposing position benefit from adopting?
This model builds up a clear picture of both sides of an argument and seeks a compromise. It is particularly useful when people tend to disagree strongly on the issue discussed, allowing you to approach opposing arguments in good faith.
Say you want to argue that the internet has had a positive impact on education. You might:
- Acknowledge that students rely too much on websites like Wikipedia
- Argue that teachers view Wikipedia as more unreliable than it really is
- Suggest that Wikipedia’s system of citations can actually teach students about referencing
- Suggest critical engagement with Wikipedia as a possible assignment for teachers who are skeptical of its usefulness.
You don’t necessarily have to pick one of these models—you may even use elements of both in different parts of your essay—but it’s worth considering them if you struggle to structure your arguments.
Regardless of which approach you take, your essay should always feature an introduction, a body, and a conclusion.
Introducing your argument
Like other academic essays, an argumentative essay begins with an introduction. The introduction serves to capture the reader’s interest, provide background information, present your thesis statement, and (in longer essays) to summarize the structure of the body.
Hover over different parts of the example below to see how a typical introduction works.
The body: Developing your argument
The body of an argumentative essay is where you develop your arguments in detail. Here you’ll present evidence, analysis, and reasoning to convince the reader that your thesis statement is true.
In the standard five-paragraph format for short essays, the body takes up three of your five paragraphs. In longer essays, it will be more paragraphs, and might be divided into sections with headings.
This example paragraph takes a Rogerian approach: It first acknowledges the merits of the opposing position and then highlights problems with that position.
Hover over different parts of the example to see how a body paragraph is constructed.
Concluding your argument
An argumentative essay ends with a conclusion that summarizes and reflects on the arguments made in the body.
No new arguments or evidence appear here, but in longer essays you may discuss the strengths and weaknesses of your argument and suggest topics for future research. In all conclusions, you should stress the relevance and importance of your argument.

Frequently asked questions about argumentative essays
- What’s the difference between an expository essay and an argumentative essay?
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.
- When do I need to cite sources in an essay?
All essays written at a university level need to properly cite their sources (with the exception of exams or in-class exercises).
Citations should appear in your essay wherever you quote or paraphrase information from a source. These citations usually correspond to entries in a bibliography or reference list at the end of your essay.
- When do I write an argumentative essay?
The majority of the essays written at university are some sort of argumentative essay. Unless otherwise specified, you can assume that the goal of any essay you’re asked to write is argumentative: To convince the reader of your position using evidence and reasoning.
In composition classes you might be given assignments that specifically test your ability to write an argumentative essay. Look out for prompts including instructions like “argue,” “assess,” or “discuss” to see if this is the goal.
