How to write a university
essay introduction —
UK guide with examples.
The introduction sets the marker's expectations for everything that follows. Get it right and you've already signalled a strong essay. Here's the exact structure — and worked examples.
The introduction is the first thing your marker reads and the section most likely to shape their overall impression of your essay. A strong introduction tells the marker you know what you're doing before they've read a single body paragraph.
The marker test
A marker who reads only your introduction should be able to answer three questions: What is this essay about? What does it argue? How does it develop that argument? If any are unanswerable, it needs reworking.
What an introduction needs to do
An introduction has one job: prepare the reader for the argument that follows. Every sentence should be in service of three things: context, signposting, and thesis.
The three-part structure
1
First 1–3 sentences
Context
Situate the essay in its broader field. Two or three sentences that establish the topic, its significance, and why the question matters. Not a history — a frame.
2
Middle sentences
Signposting
Briefly outline how the essay develops. "This essay first examines X, before considering Y, and concludes that Z." One or two sentences.
3
Final sentence(s)
Thesis
State your central argument explicitly. The single most important sentence in your introduction. "This essay argues that..." followed by a clear, specific claim.
Bad introduction vs good introduction — real examples
Both examples respond to: "To what extent does Bourdieu's concept of cultural capital explain educational inequality in the UK?"
"Education is an important part of society. For many years, sociologists have studied educational inequality and its causes. There are many different theories that try to explain why some students do better than others at school and university. This essay will look at Bourdieu's concept of cultural capital and discuss whether it explains educational inequality in the UK. There are arguments for and against this view."
Problems: Generic opening. No thesis — "will look at" and "discuss" are not positions. "Arguments for and against" signals fence-sitting. No signposting.
"Educational inequality in the UK remains persistent despite decades of policy intervention, with students from lower socioeconomic backgrounds consistently underperforming relative to their more advantaged peers. Sociological frameworks offer competing explanations for this gap, ranging from material disadvantage to cultural reproduction. This essay argues that Bourdieu's concept of cultural capital provides the most compelling account of this inequality, as it identifies the mechanisms through which social advantage is reproduced within educational institutions — though it has significant limitations in accounting for the experiences of high-achieving working-class students. The essay first examines Bourdieu's framework before considering its critics, ultimately concluding that cultural capital remains the most powerful explanatory tool available despite these limitations."
Strengths: Specific contextual claim. Names competing frameworks. Clear thesis with position and qualification. Signposts the structure.
What to leave out of your introduction
- Dictionary definitions. "According to the Oxford English Dictionary..." — avoid unless contesting a definition.
- Historical overviews. "Since the industrial revolution..." — background belongs in the body if directly relevant.
- Everything you're going to argue. The introduction frames; the body makes the argument.
- Rhetorical questions. "But what is cultural capital really?" — state your argument instead.
- "In this essay I will..." Replace with "This essay argues..." or state the thesis directly.

Why you should write it last
The introduction is often best written after the rest of the essay is complete. You can't accurately state your thesis until you know what you've argued.
The practical approach: write a rough introduction with a provisional thesis, draft all body paragraphs and conclusion, then rewrite the introduction to accurately reflect the argument you've made.
Introduction checklist
- Does the opening sentence contextualise the topic specifically — not generically?
- Is there a clear thesis statement that takes a position?
- Is the thesis specific enough that someone could disagree with it?
- Does the signposting reflect what the essay actually does?
- Is there anything in the introduction that should be in the body?
- Does it avoid "In this essay I will discuss..."?
- If you read only this paragraph, would you know what the essay argues?
