Before writing a word, a strong writer knows exactly which kind of essay they're building. Each type has its own purpose, structure, and rules for evidence.
Before writing a word, a strong writer knows exactly what kind of essay is being asked for. Each type has its own purpose, structure and rules for evidence, and mixing them up is one of the quickest ways to lose marks.
Not every essay does the same job. Some argue, some explain, some tell a story, some paint a picture, and some compare two things side by side. This guide, the third in our Academic & Essay Writing series, explains the main essay types, how each is organised, how to recognise which type a prompt is asking for, how types blend, and the mistakes typical of each. It adds other patterns you will meet, such as cause and effect, and the discursive and reflective essays that appear in many exams. It includes two worked examples, a checklist, common mistakes and ten practice questions.
It follows Thesis Statements and leads into Evidence, Citations & Avoiding Plagiarism. It also works with Essay Structure and How to Write a Perfect Paragraph.
The Purdue Online Writing Lab explains that these genres, also called the modes of discourse, have been criticised by some composition scholars, but that they are so widely used that students need to understand and produce them. In other words: real writing often mixes modes, but classroom and exam questions usually name one, and the examiner expects you to deliver it.
Each type answers a different question from the reader:
Diagram 1. Different exam boards and teachers may name the types a little differently.
An argumentative essay takes a clear position on a debatable issue and defends it with evidence and logical reasoning, usually also addressing at least one opposing view.
"Should schools limit phone use in class?"
Schools should limit phone use in class to set learning tasks, because unrestricted use distracts students from the lesson.
Persuasive or argumentative? Many people use the two words interchangeably. Some curriculum guides distinguish them, saying persuasion may use emotion and character appeals, while argument relies on evidence and reasoning. In school essays, treat both as: choose a side, prove it.
An expository essay explains or informs. The goal is for the reader to understand a topic thoroughly, not to adopt a particular opinion. Writing guides describe it as examining the evidence to reach a conclusion, rather than defending a position fixed in advance.
"Explain how a school phone policy works."
A typical school phone policy has three parts: where phones may be used, when they may be used, and what happens when a rule is broken.
A narrative essay tells a story, often from the writer's own experience, and builds toward a point, lesson or reflection. A personal narrative is based on real events. In some exams, "narrative writing" can mean an invented story, so always check whether the question wants a true account or allows fiction.
"Describe a moment when you learned something unexpected."
The day my phone rang in the middle of a maths test, I learned how quickly a quiet room can turn against you.
A descriptive essay paints a vivid picture of a person, place, object or experience, using sensory detail. The Writing Centre guides describe it as appealing to the senses so that the reader can imagine the scene.
"Describe a busy classroom."
The classroom hummed with a dozen small noises: chairs scraping, pages turning, and the soft click of pens against desks.
A compare-and-contrast essay examines the similarities and/or differences between two or more subjects. It is a kind of expository writing with a specific organisation. It works best when the thesis says why the comparison matters, not just that there are similarities.
Diagram 2. Choose one method and keep to it throughout the essay.
Use clear comparison words: similarly, likewise, in the same way, both; and contrast words: however, whereas, on the other hand, unlike. See Transitions & Cohesion.
Two more types appear in many school and exam syllabuses, though names vary between boards.
| Feature | Argumentative | Discursive |
|---|---|---|
| Aim | Convince the reader | Explore and weigh views |
| Position | One side, defended | Several sides, fairly presented |
| Tone | Firm, persuasive | Balanced, measured |
| Conclusion | Restates the claim | May give a reasoned judgement |
Inside expository and academic writing, you will often organise ideas using one of these patterns. The Purdue OWL lists them as additional modes: definition, process, classification, comparison and contrast, and cause and effect. Problem and solution is another common one.
| Pattern | Main question | Typical outline |
|---|---|---|
| Definition | What is it? | Term, category, features, examples |
| Process | How is it done? | Materials, steps in order, result |
| Classification | What kinds are there? | Principle of sorting, then each category |
| Cause and effect | Why did it happen, or what follows? | Causes then effects (or the reverse) |
| Problem and solution | What is wrong, and how can it be fixed? | Problem, causes, solutions, best choice |
Essay prompts often hide the type in the verbs. Read them in three layers:
Diagram 3. Underline all three before you plan.
| Task words in the prompt | Likely type |
|---|---|
| argue, persuade, convince, should, "do you agree?" | Argumentative |
| discuss, "to what extent", "consider both sides" | Discursive (or argumentative; check the instructions) |
| explain, "how does", "why does", define, outline | Expository |
| narrate, tell the story of, "describe a time when" | Narrative |
| describe (a person, place, object) | Descriptive |
| compare, contrast, "similarities and differences" | Compare-and-contrast |
| "what did you learn from", "reflect on" | Reflective |
Careful with "describe" and "discuss". "Describe a time when…" asks for a story (narrative), while "Describe your grandmother's kitchen" asks for a picture (descriptive). "Discuss" can mean a balanced discussion or a developed argument. When the type is unclear, read the instructions and the marking criteria, or ask your teacher.
| Type | Person | Tone and style |
|---|---|---|
| Argumentative | Usually third person; "I" sparingly | Firm, evidence-based, formal |
| Expository | Third person | Neutral, clear, factual |
| Narrative | Usually first person | Personal, vivid, reflective |
| Descriptive | First or third | Sensory, figurative, atmospheric |
| Compare-and-contrast | Third person | Balanced, organised |
| Discursive | Third person | Balanced, measured, formal |
| Type | Typical order of paragraphs |
|---|---|
| Argumentative | Introduction with thesis, reason 1, reason 2, counter-argument and answer, conclusion |
| Discursive | Introduction naming the issue, view 1, view 2, weighing the views, conclusion |
| Expository | Introduction with central point, each part, step or cause in logical order, conclusion |
| Narrative | Opening scene, build-up, turning point, outcome, reflection |
| Descriptive | Dominant impression, details in a clear order (for example near to far), closing image |
| Compare-and-contrast | Introduction with thesis, block or point-by-point comparison, conclusion on what the comparison shows |
These are starting patterns, not rules. For the full shape of an essay, see Essay Structure.
Longer or more advanced essays often blend elements. An argumentative essay might open with a short story as a hook. A compare-and-contrast essay might end with an argument about which choice is better. A descriptive essay might include a narrative moment. The key is to identify the primary type that decides the backbone of the essay, and use the other elements to support it.
| Type | Typical mistake |
|---|---|
| Argumentative | Opinion without evidence, or ignoring opposing views |
| Expository | Slipping into persuasion when the task asks for explanation |
| Narrative | A story with no reflection, so the reader is unsure why it matters |
| Descriptive | Only visual detail, and no organising order or dominant impression |
| Compare-and-contrast | Switching between block and point-by-point; listing differences without a point |
| Discursive | Listing views without weighing them, or secretly arguing one side |
Topic: phones in school. The same topic can give six different essays.
| Type | Controlling idea |
|---|---|
| Argumentative | Schools should allow phones in class only for set learning tasks, because unrestricted use distracts students. |
| Discursive | Phones in class bring real benefits and real risks, and schools must weigh both. |
| Expository | A school phone policy has three parts: where, when and consequences. |
| Narrative | The day my phone rang during a test taught me about trust. |
| Descriptive | A classroom where every screen glows. |
| Compare-and-contrast | Phones and textbooks both give information, but they differ in distraction and cost. |
What changes. The topic stays the same, but the purpose, structure, tone, evidence and conclusion are different each time. The thesis (or central idea) is the quickest way to see which type you are writing.
Try it yourself. Name the type and the task, content and limiting words in this prompt: "Discuss the advantages and disadvantages of online learning for secondary students."
Sample answer: Task word: "discuss", with "advantages and disadvantages", so a discursive (balanced) essay. Content words: "online learning". Limiting words: "secondary students", so keep to that age group, not universities or adults.

Misreading the type is one of the most common reasons otherwise well-written essays lose marks. Recognising the type first, before you write a thesis or plan paragraphs, builds the entire essay on the right foundation. Move on to Evidence, Citations & Avoiding Plagiarism, and use Transitions & Cohesion to link what you write.
Activity: give students one topic and ask them to write a one-sentence thesis or central idea for each of six essay types. Then give them five prompts to decode in pairs, underlining task, content and limiting words and naming the type.
Please note: essay types are taught in slightly different ways by different exam boards and countries, and some scholars question the modes-of-discourse approach. This guide presents common school usage; students should follow their own syllabus and teacher.
