Text Types and Structure
Understand text types and structure in English. Organise paragraphs, manage register, link ideas smoothly, and build texts readers can follow.
What Are Text Types and Structure?
Text types and structure are essential for writing well in English. Each type has its own structure, purpose, and conventions—you need them to communicate clearly.
📋 Quick Reference
Main Text Types
Texts differ by purpose, features, and what readers expect.
| Type | Purpose | Structure | Example |
|---|---|---|---|
| Descriptive | Describe people, places, objects | Introduction + details + closing | A description of a city |
| Narrative | Tell a story or sequence of events | Beginning + middle + ending | A holiday story |
| Expository | Explain or inform | Thesis + supporting points + conclusion | Essay about the environment |
| Argumentative | Persuade or convince | Thesis + counterarguments + conclusion | Opinion on technology |
| Instructional | Give directions or steps | Goal + steps + result | A recipe |
| Correspondence | Communicate with someone directly | Greeting + body + closing | Formal/informal email |
Description: "My hometown is a beautiful place…"
Narrative: "Last summer I went to…"
Argumentative: "I believe technology is…"
Choosing a Text Type
Choose according to:
- The purpose of your writing
- Your target audience
- Whether the context is formal or informal
- Any specific assignment requirements
General Structure of Texts
Most English texts follow a basic three-part structure.
| Part | Role | Content | Length |
|---|---|---|---|
| Introduction | Present the topic | Thesis, background, aims | About 10–15% of the text |
| Body / development | Develop your ideas | Paragraphs with arguments or examples | About 70–80% |
| Conclusion | Summarize and close | Summary, final view, suggestion | About 10–15% |
Introduction: "In this essay I will analyse the benefits of technology…"
Body: "First, technology improves communication…"
Conclusion: "In conclusion, technology is beneficial…"
What Each Part Does
Each section has typical jobs:
- Introduction: engage the reader, present the topic
- Body: argue, illustrate, explain
- Conclusion: summarise, express a final viewpoint
Paragraphs: Structure and Development
Paragraphs are the basic organising unit—each paragraph should develop one controlling idea.
| Part | Role | Example |
|---|---|---|
| Topic sentence | Introduce the main idea | Technology has revolutionized communication. |
| Supporting sentences | Explain and expand the idea | First, it allows instant messaging… |
| Examples / evidence | Illustrate the point | For example, social media platforms… |
| Closing sentence | Round off the paragraph | Therefore, communication is now faster. |
Topic sentence: "Technology has revolutionized communication."
Development: "First of all, it allows instant messaging…"
Example: "For example, social media platforms…"
Paragraph Rules
Every paragraph should:
- Express one central idea
- Stay coherent and linked together
- Be an appropriate length (often about 3–7 sentences)
- Connect to the paragraph before and after
Formal vs Informal Register
Register sets the tone—it should suit the situation and who will read your text.
| Feature | Formal | Informal |
|---|---|---|
| Vocabulary | More precise or formal wording | Simpler, everyday wording |
| Contractions | Avoid them (e.g. I will, do not) | Often use them (I'll, don't) |
| Sentence patterns | Longer or more complex sentences | Often shorter sentences |
| Pronouns | Sometimes limit direct I/you | I and you are common |
| Connectors | However, moreover | But, plus, too |
Formal: "I would like to express my gratitude…"
Informal: "Thanks a lot for everything!"
Formal: "Furthermore, it is important to note…"
Informal: "Also, you should know…"
When to Use Each Register
Adapt to:
- Formal: academic essays, job letters, formal reports
- Informal: personal emails to friends, informal blogs, messages
- Context: workplace vs social setting
- Audience: for example supervisors vs peers
Linkers and Transitions
Linking words help readers follow your argument smoothly.
| Function | Linkers | Example |
|---|---|---|
| Adding ideas | Furthermore, moreover, in addition | Furthermore, technology improves education. |
| Contrast | However, nevertheless, on the other hand | However, there are disadvantages too. |
| Cause | Because, due to, as a result of | Because of technology, communication is faster. |
| Result | Therefore, consequently, thus | Therefore, we should use it wisely. |
| Sequence / time | First, then, finally, meanwhile | First, I will discuss the advantages. |
| Example | For example, for instance, such as | For example, smartphones are very useful. |
Addition: "Furthermore, technology improves education."
Contrast: "However, there are some disadvantages."
Result: "Therefore, we should use technology thoughtfully."
Common Mistakes
Better: One main idea per paragraph ✅
Each paragraph needs a clear focus
Better: Use transitions where needed ✅
Transitions improve flow between ideas
Better: Adapt register to situation ✅
Formal essays need formal language; chats with friends can be informal
Better: Clear introduction, body, conclusion ✅
Structure helps readers follow your line of thought

Readers should understand how ideas fit together.
- Choose appropriate linkers
- Keep to one thread per paragraph
