Hook, context, thesis and roadmap — the four moves that make a marker want to keep reading.
7 min read · Written by UK academic writers
A strong essay introduction sets the context, narrows to the specific question, states your thesis or argument, and signposts the structure to come. It should be concise — usually around 10% of your word count — and make your position clear from the first paragraph.
Your introduction is the first thing a marker reads and it shapes how they judge everything that follows. A good one signals that you understand the question and have a clear plan to answer it. Here is a reliable four-part structure you can adapt to any essay.
Begin with a sentence or two that establishes the topic and why it matters — not a dictionary definition or a sweeping claim about history. Keep it specific to the question so the reader is oriented immediately.
Move from the broad context to the precise issue your essay addresses. This shows you understand the scope of the question and are not going to wander off topic.
The thesis is the single most important sentence in your essay: it states your argument or position. Make it clear and arguable, so the marker knows exactly what you will defend.
Avoid vague openings like "this essay will discuss". State a position: "This essay argues that…".
Briefly outline the route your essay will take. A short roadmap helps the marker follow your argument and shows you have planned a logical sequence.
For the question "To what extent did social media cause political polarisation?", a strong intro would set the context (the rise of social platforms), narrow to the debate on causation, state a thesis ("social media amplified rather than caused polarisation"), then signpost the three areas the essay will examine.
Around 10% of the total word count. For a 2,000-word essay that is roughly 200 words.
Many strong writers draft a rough introduction, write the body, then rewrite the introduction so it matches the argument that actually emerged.
A light hook can help, but in academic writing relevance beats drama. Lead with focused context rather than a gimmick.
No. A thesis should be a clear, arguable statement — your answer to the question, not a restatement of it.

An effective essay introduction does three specific jobs, not one: it establishes context briefly (a sentence or two orienting the reader in the topic, without a generic "since the dawn of time" opening), it defines how the essay will interpret the question (especially important where a question could reasonably be read more than one way), and it states a clear thesis or line of argument the rest of the essay will follow. UK markers generally expect the thesis statement to appear explicitly, usually in the final sentence or two of the introduction, rather than leaving the reader to infer the essay's position from the body paragraphs.
A common structural fault is an introduction that summarises what each body paragraph will say in sequence ("firstly this, then this, then this") - this reads as a table of contents rather than an argument and rarely earns credit. A stronger approach states the overall position and its key supporting logic in a couple of sentences, without pre-empting every individual point. As a proportion of the whole essay, an introduction of roughly 8-10% of the total word count is typical for undergraduate essays - long enough to set up the argument properly, short enough to leave the bulk of the word count for developing it.
