How to write an essay introduction
A good introduction paragraph is both engaging and informative. The main goals of your introduction are to:
- Catch your reader’s attention and interest.
- Give context and background on your topic.
- Set up the focus and purpose 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, and make sure it’s directly relevant to what follows. Some strategies to write a hook include:
- A surprising fact or statistic
- A question
- A quotation
- A brief anecdote
- A broad summary
Always avoid cliches and generalizations:
- Dictionary definitions
- Sweeping claims that use words like “always” or “everywhere”
In academic essays, don’t worry too much about coming up with a hugely creative or exciting hook — it’s more important that your first sentence leads the reader into your essay and gives a good sense of what it will be about.
In our example, the first sentence simply introduces the topic in a concise, compelling way:
This sentence makes a bold claim that emphasizes the importance of the topic, but it doesn’t over-generalize. It gives a good idea of the essay’s general purpose and approach, but doesn’t give away too much information.
Step 2: Contextualize your topic
Next, give your reader the background information they need to understand your topic and argument. Depending on the subject of your essay, this might include:
- Historical, geographical, or social context
- Definitions of unfamiliar terms
- A summary of current scholarly debates, theories or research
The information you give 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 example, the writer takes a couple of sentences to introduce the topic and sketch the social context that the essay will address:
Step 3: Establish your purpose and position
Now it’s time to narrow your focus and show what your essay aims to do. This is your thesis statement — a sentence or two that sums up your focus and overall argument. This part of the introduction paragraph is important to set the limits of your essay and let the reader know exactly which aspect of the topic you will address.
The thesis statement often takes the form of a strong argument for a particular position. But in expository or analytical essays, it’s more like a map of the central points that the essay will demonstrate and analyze, as in our example:
The two-sentence thesis statement covers the main points that the essay will discuss: Braille’s development from other tactile reading systems, its effect on blind people’s status, and the social processes that allowed it to become successful.
Although in this case there is no direct argumentative statement, the thesis still takes a clear position: the underlying argument is for Braille’s importance in relation to the social context of the time.
Step 4: 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.
Whether you write your introduction first, last or somewhere in between, you should return to it and check that it matches the content of the essay. Make sure you have included only necessary and relevant information.
