How to Write an Essay Introduction: A Simple 3-Part Method

Part 1: Open with a focused hook

A hook is a first sentence that makes the topic feel worth reading about. A surprising fact, a short scenario or a precise question works better than a broad claim such as "Since the dawn of time, people have argued about…".

Keep the hook connected to your argument. If the essay is about school start times, a sentence about teenage sleep research is relevant; a famous quotation about time in general is not.

Part 2: Give the reader context

Next, explain the background the reader needs: key terms, the situation, or the debate you are entering. Two or three sentences are usually enough.

Avoid summarising every body paragraph here. Context prepares the argument; the body paragraphs deliver the evidence.

Part 3: End with your thesis

Finish the paragraph with a thesis statement — one or two sentences that state your position and, ideally, the main reasons. For example: "Schools should start after 8:30 a.m. because later times improve attendance, mood and test performance."

A thesis should be arguable. "Sleep is important" is a fact; "Later start times are worth the cost of changing bus schedules" is a claim someone could dispute.

Budget the length

For a 1,000-word essay, an introduction of about 80–120 words is a sensible plan. For a 3,000-word paper, 250–300 words gives room for more context without delaying the argument.

Paste your introduction into the word counter to check it is proportional. Many writers draft the introduction last, once they know exactly what the essay argues.
