How to Write an Essay Introduction | 4 Steps & Examples
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.
Step 1: Hook your reader
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.
Step 2: Give background information
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:
Step 3: Present your thesis statement
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.
Step 4: Map your essay’s structure
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.
Step 5: Check and revise
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.

Frequently asked questions about the essay introduction
- What goes in an essay introduction?
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.
- What is a hook?
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.
- What is a thesis statement?
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.
- Why do I need a thesis statement?
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.
- What is the structure of an essay?
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.
