How to write an essay: a clear structure that works
A good essay is not about big words or filling the page. It is a clear argument, well organised and backed by evidence. Once you have a reliable structure and a process to follow, the blank page stops being scary. Here is the system, from planning to final proofread.

Marks are lost far more often on structure and relevance than on intelligence. A student who writes a focused, well-argued essay that answers the exact question will beat a cleverer one who rambles. The aim of this guide is simple: give you a repeatable process so every essay you write has a clear argument and a logical shape.
Understand the question first
The single most common reason essays underperform is that they don't answer the question asked. Before writing a word, break the title down. Identify the instruction word (analyse, evaluate, discuss, compare), the topic, and any limits on scope. "Evaluate" wants a judgement with evidence on both sides; "describe" does not. Answer the question in front of you, not the one you wish you'd been set.
What common instruction words actually want
Plan before you write
Planning feels like a delay but saves hours and raises your mark. Decide your overall argument (your thesis) first, then list the points that support it in a logical order. Each point becomes a paragraph or section. A rough plan also stops you writing yourself into a corner halfway through.
Write your thesis as a single sentence before you start: "This essay argues that X, because of A, B, and C." If you can't, you're not ready to write yet, you're still working out what you think.
The essay structure
Introduction (~10%)
Frame the topic and why it matters, define your scope, and end with a clear thesis statement that directly answers the question.
Body (~80%)
A series of paragraphs, each making one point with evidence, arranged in a logical order that builds your argument. This is where the marks are.
Conclusion (~10%)
Restate your answer, summarise how your points support it, and end with the wider significance. Don't introduce new evidence here.
PEEL paragraphs
The body is where essays are won and lost. Keep each paragraph to one idea and use the PEEL structure so every paragraph earns its place:
Point: open with the single claim this paragraph makes.
Evidence: support it with a quote, data, study, or example, and reference it.
Explanation: spell out how the evidence proves your point. This is where analysis marks live.
Link: connect back to the question, or forward to your next point, so the argument flows.
The difference between a 2:1 and a first is usually the Explanation step: weaker essays describe evidence, stronger ones analyse it and use it to build an argument. Whenever you use a source, make sure you reference it correctly, our referencing and plagiarism guide covers the basics.
Edit and proofread
First drafts are for getting ideas down; marks come from editing. Leave the draft for a few hours, then return and read for structure first, then language. Cut anything that does not serve your argument, even if you like it.
Check every paragraph answers the question and links to your thesis.
Cut filler and repetition; shorter, clearer sentences read as more confident.
Read the essay aloud to catch clunky phrasing and missing words.
Check your referencing and formatting against the required style guide.
Run a final spellcheck, then proofread once more by eye for the things it misses.
Common mistakes
Not answering the question
The most expensive mistake. A brilliant essay on the wrong question still fails. Re-read the title as you write.
Describing instead of analysing
Listing what sources say isn't enough. Explain what the evidence means for your argument.
No clear thesis
Without a central argument, an essay becomes a list of facts. State your position up front and defend it.
Weak structure
Paragraphs that jump between ideas lose the reader. One idea per paragraph, in a logical order.
Leaving it to the last minute
Good essays need a planning, drafting, and editing gap. Cramming removes the editing stage, where most marks are won.
Frequently asked questions
What is the basic structure of an essay?
An essay has three parts: an introduction that sets up the question and states your argument (thesis), a body of paragraphs that each make one point with evidence, and a conclusion that draws the argument together. The body is the largest part and should follow a logical order that builds toward your conclusion.
How do you start an essay introduction?
Open with a sentence that frames the topic and its importance, briefly define the scope of what you will and won't cover, and finish with a clear thesis statement. Avoid long, vague openers and dictionary definitions; get to your argument quickly.
What is a PEEL paragraph?
PEEL is a structure for body paragraphs: Point (the claim), Evidence (a quote, data, or example), Explanation (how the evidence supports your point), and Link (back to the question or on to the next idea). It keeps each paragraph focused and tied to your thesis.
How long should an essay introduction and conclusion be?
As a rough guide, each should be around 10 percent of the total word count. For a 2,000-word essay, that's roughly 200 words each, leaving about 1,600 words for the body. Don't pad the introduction; a tight, clear thesis beats a long wind-up.
How do you get a first-class mark on an essay?
Answer the exact question asked, build a clear and consistent argument, use evidence critically rather than just describing it, and show you understand different viewpoints before reaching a reasoned conclusion. Strong structure, correct referencing, and careful proofreading separate a first from a 2:1.
