How to Write an Essay Introduction | 4 Steps & Examples
Published on February 4, 2019 by Shona McCombes . Revised on September 14, 2022.
A good introduction paragraph is an essential part of any academic essay . It sets up your argument and tells the reader what to expect.
The main goals of an introduction are to:
- Catch your reader’s attention.
- Give background on your topic.
- Present your thesis statement —the central point of your essay.
This introduction example is taken from our interactive essay example on the history of Braille.
The invention of Braille was a major turning point in the history of disability. The writing system of raised dots used by visually impaired people was developed by Louis Braille in nineteenth-century France. In a society that did not value disabled people in general, blindness was particularly stigmatized, and lack of access to reading and writing was a significant barrier to social participation. The idea of tactile reading was not entirely new, but existing methods based on sighted systems were difficult to learn and use. As the first writing system designed for blind people’s needs, Braille was a groundbreaking new accessibility tool. It not only provided practical benefits, but also helped change the cultural status of blindness. This essay begins by discussing the situation of blind people in nineteenth-century Europe. It then describes the invention of Braille and the gradual process of its acceptance within blind education. Subsequently, it explores the wide-ranging effects of this invention on blind people’s social and cultural lives.

Step 1: hook your reader, step 2: give background information, step 3: present your thesis statement, step 4: map your essay’s structure, step 5: check and revise, more examples of essay introductions, frequently asked questions about the essay introduction.
Your first sentence sets the tone for the whole essay, so spend some time on writing an effective hook.
Avoid long, dense sentences—start with something clear, concise and catchy that will spark your reader’s curiosity.
The hook should lead the reader into your essay, giving a sense of the topic you’re writing about and why it’s interesting. Avoid overly broad claims or plain statements of fact.
Examples: Writing a good hook
Take a look at these examples of weak hooks and learn how to improve them.
- Braille was an extremely important invention.
- The invention of Braille was a major turning point in the history of disability.
The first sentence is a dry fact; the second sentence is more interesting, making a bold claim about exactly why the topic is important.
- The internet is defined as “a global computer network providing a variety of information and communication facilities.”
- The spread of the internet has had a world-changing effect, not least on the world of education.
Avoid using a dictionary definition as your hook, especially if it’s an obvious term that everyone knows. The improved example here is still broad, but it gives us a much clearer sense of what the essay will be about.
- Mary Shelley’s Frankenstein is a famous book from the nineteenth century.
- Mary Shelley’s Frankenstein is often read as a crude cautionary tale about the dangers of scientific advancement.
Instead of just stating a fact that the reader already knows, the improved hook here tells us about the mainstream interpretation of the book, implying that this essay will offer a different interpretation.
Next, give your reader the context they need to understand your topic and argument. Depending on the subject of your essay, this might include:
- Historical, geographical, or social context
- An outline of the debate you’re addressing
- A summary of relevant theories or research about the topic
- Definitions of key terms
The information here should be broad but clearly focused and relevant to your argument. Don’t give too much detail—you can mention points that you will return to later, but save your evidence and interpretation for the main body of the essay.
How much space you need for background depends on your topic and the scope of your essay. In our Braille example, we take a few sentences to introduce the topic and sketch the social context that the essay will address:

Now it’s time to narrow your focus and show exactly what you want to say about the topic. This is your thesis statement —a sentence or two that sums up your overall argument.
This is the most important part of your introduction. A good thesis isn’t just a statement of fact, but a claim that requires evidence and explanation.
The goal is to clearly convey your own position in a debate or your central point about a topic.
Particularly in longer essays, it’s helpful to end the introduction by signposting what will be covered in each part. Keep it concise and give your reader a clear sense of the direction your argument will take.
As you research and write, your argument might change focus or direction as you learn more.
For this reason, it’s often a good idea to wait until later in the writing process before you write the introduction paragraph—it can even be the very last thing you write.
When you’ve finished writing the essay body and conclusion , you should return to the introduction and check that it matches the content of the essay.
It’s especially important to make sure your thesis statement accurately represents what you do in the essay. If your argument has gone in a different direction than planned, tweak your thesis statement to match what you actually say.
You can use the checklist below to make sure your introduction does everything it’s supposed to.
Checklist: Essay introduction
My first sentence is engaging and relevant.
I have introduced the topic with necessary background information.
I have defined any important terms.
My thesis statement clearly presents my main point or argument.
Everything in the introduction is relevant to the main body of the essay.
You have a strong introduction - now make sure the rest of your essay is just as good.
- Argumentative
- Literary analysis
This introduction to an argumentative essay sets up the debate about the internet and education, and then clearly states the position the essay will argue for.
The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts is on the rise, and its role in learning is hotly debated. For many teachers who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its critical benefits for students and educators—as a uniquely comprehensive and accessible information source; a means of exposure to and engagement with different perspectives; and a highly flexible learning environment.
This introduction to a short expository essay leads into the topic (the invention of the printing press) and states the main point the essay will explain (the effect of this invention on European society).
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.
This introduction to a literary analysis essay , about Mary Shelley’s Frankenstein , starts by describing a simplistic popular view of the story, and then states how the author will give a more complex analysis of the text’s literary devices.
Mary Shelley’s Frankenstein is often read as a crude cautionary tale. Arguably the first science fiction novel, its plot can be read as a warning about the dangers of scientific advancement unrestrained by ethical considerations. In this reading, and in popular culture representations of the character as a “mad scientist”, Victor Frankenstein represents the callous, arrogant ambition of modern science. However, far from providing a stable image of the character, Shelley uses shifting narrative perspectives to gradually transform our impression of Frankenstein, portraying him 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.
Your essay introduction should include three main things, in this order:
- An opening hook to catch the reader’s attention.
- Relevant background information that the reader needs to know.
- A thesis statement that presents your main point or argument.
The length of each part depends on the length and complexity of your essay .
The “hook” is the first sentence of your essay introduction . It should lead the reader into your essay, giving a sense of why it’s interesting.
To write a good hook, avoid overly broad statements or long, dense sentences. Try to start with something clear, concise and catchy that will spark your reader’s curiosity.
A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.
The thesis statement is essential in any academic essay or research paper for two main reasons:
- It gives your writing direction and focus.
- It gives the reader a concise summary of your main point.
Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.
The structure of an essay is divided into an introduction that presents your topic and thesis statement , a body containing your in-depth analysis and arguments, and a conclusion wrapping up your ideas.
The structure of the body is flexible, but you should always spend some time thinking about how you can organize your essay to best serve your ideas.

What Makes a Good Literature Paper?
An argument.
When you write an extended literary essay, often one requiring research, you are essentially making an argument. You are arguing that your perspective-an interpretation, an evaluative judgment, or a critical evaluation-is a valid one.
A debatable thesis statement
Like any argument paper you have ever written for a first-year composition course, you must have a specific, detailed thesis statement that reveals your perspective, and, like any good argument, your perspective must be one which is debatable.
You would not want to make an argument of this sort:
Shakespeare's Hamlet is a play about a young man who seeks revenge. That doesn't say anything-it's basically just a summary and is hardly debatable.
A better thesis would be this:
Hamlet experiences internal conflict because he is in love with his mother. That is debatable, controversial even. The rest of a paper with this argument as its thesis will be an attempt to show, using specific examples from the text and evidence from scholars, (1) how Hamlet is in love with his mother, (2) why he's in love with her, and (3) what implications there are for reading the play in this manner.
You also want to avoid a thesis statement like this:
Spirituality means different things to different people. King Lear , The Book of Romans , and Zen and the Art of Motorcycle Maintenance each view the spirit differently. Again, that says nothing that's not already self-evident. Why bother writing a paper about that? You're not writing an essay to list works that have nothing in common other than a general topic like "spirituality." You want to find certain works or authors that, while they may have several differences, do have some specific, unifying point. That point is your thesis.
Lear , Romans , and Zen each view the soul as the center of human personality. Then you prove it, using examples from the texts that show that the soul is the center of personality.

Essay Structure
Writing an academic essay means fashioning a coherent set of ideas into an argument. Because essays are essentially linear—they offer one idea at a time—they must present their ideas in the order that makes most sense to a reader. Successfully structuring an essay means attending to a reader's logic.
The focus of such an essay predicts its structure. It dictates the information readers need to know and the order in which they need to receive it. Thus your essay's structure is necessarily unique to the main claim you're making. Although there are guidelines for constructing certain classic essay types (e.g., comparative analysis), there are no set formula.
Answering Questions: The Parts of an Essay
A typical essay contains many different kinds of information, often located in specialized parts or sections. Even short essays perform several different operations: introducing the argument, analyzing data, raising counterarguments, concluding. Introductions and conclusions have fixed places, but other parts don't. Counterargument, for example, may appear within a paragraph, as a free-standing section, as part of the beginning, or before the ending. Background material (historical context or biographical information, a summary of relevant theory or criticism, the definition of a key term) often appears at the beginning of the essay, between the introduction and the first analytical section, but might also appear near the beginning of the specific section to which it's relevant.
It's helpful to think of the different essay sections as answering a series of questions your reader might ask when encountering your thesis. (Readers should have questions. If they don't, your thesis is most likely simply an observation of fact, not an arguable claim.)
"What?" The first question to anticipate from a reader is "what": What evidence shows that the phenomenon described by your thesis is true? To answer the question you must examine your evidence, thus demonstrating the truth of your claim. This "what" or "demonstration" section comes early in the essay, often directly after the introduction. Since you're essentially reporting what you've observed, this is the part you might have most to say about when you first start writing. But be forewarned: it shouldn't take up much more than a third (often much less) of your finished essay. If it does, the essay will lack balance and may read as mere summary or description.
"How?" A reader will also want to know whether the claims of the thesis are true in all cases. The corresponding question is "how": How does the thesis stand up to the challenge of a counterargument? How does the introduction of new material—a new way of looking at the evidence, another set of sources—affect the claims you're making? Typically, an essay will include at least one "how" section. (Call it "complication" since you're responding to a reader's complicating questions.) This section usually comes after the "what," but keep in mind that an essay may complicate its argument several times depending on its length, and that counterargument alone may appear just about anywhere in an essay.
"Why?" Your reader will also want to know what's at stake in your claim: Why does your interpretation of a phenomenon matter to anyone beside you? This question addresses the larger implications of your thesis. It allows your readers to understand your essay within a larger context. In answering "why", your essay explains its own significance. Although you might gesture at this question in your introduction, the fullest answer to it properly belongs at your essay's end. If you leave it out, your readers will experience your essay as unfinished—or, worse, as pointless or insular.
Mapping an Essay
Structuring your essay according to a reader's logic means examining your thesis and anticipating what a reader needs to know, and in what sequence, in order to grasp and be convinced by your argument as it unfolds. The easiest way to do this is to map the essay's ideas via a written narrative. Such an account will give you a preliminary record of your ideas, and will allow you to remind yourself at every turn of the reader's needs in understanding your idea.
Essay maps ask you to predict where your reader will expect background information, counterargument, close analysis of a primary source, or a turn to secondary source material. Essay maps are not concerned with paragraphs so much as with sections of an essay. They anticipate the major argumentative moves you expect your essay to make. Try making your map like this:
- State your thesis in a sentence or two, then write another sentence saying why it's important to make that claim. Indicate, in other words, what a reader might learn by exploring the claim with you. Here you're anticipating your answer to the "why" question that you'll eventually flesh out in your conclusion.
- Begin your next sentence like this: "To be convinced by my claim, the first thing a reader needs to know is . . ." Then say why that's the first thing a reader needs to know, and name one or two items of evidence you think will make the case. This will start you off on answering the "what" question. (Alternately, you may find that the first thing your reader needs to know is some background information.)
- Begin each of the following sentences like this: "The next thing my reader needs to know is . . ." Once again, say why, and name some evidence. Continue until you've mapped out your essay.
Your map should naturally take you through some preliminary answers to the basic questions of what, how, and why. It is not a contract, though—the order in which the ideas appear is not a rigid one. Essay maps are flexible; they evolve with your ideas.
Signs of Trouble
A common structural flaw in college essays is the "walk-through" (also labeled "summary" or "description"). Walk-through essays follow the structure of their sources rather than establishing their own. Such essays generally have a descriptive thesis rather than an argumentative one. Be wary of paragraph openers that lead off with "time" words ("first," "next," "after," "then") or "listing" words ("also," "another," "in addition"). Although they don't always signal trouble, these paragraph openers often indicate that an essay's thesis and structure need work: they suggest that the essay simply reproduces the chronology of the source text (in the case of time words: first this happens, then that, and afterwards another thing . . . ) or simply lists example after example ("In addition, the use of color indicates another way that the painting differentiates between good and evil").
