Key concepts
What is a Paragraph?
A paragraph is a group of sentences that develops one single idea. Every sentence in the paragraph must relate to the topic sentence. A well-written paragraph is:
- Unified: all sentences relate to one idea
- Coherent: sentences flow logically from one to the next
- Complete: the idea is fully developed, not just mentioned
The Topic Sentence
The topic sentence is the first (or occasionally second) sentence of a paragraph. It tells the reader what the paragraph is about and controls everything that follows.
A good topic sentence:
- States one clear, specific idea (not a fact, not a question)
- Is neither too broad nor too narrow
- Can be disagreed with (it makes a claim)
| Too broad | Too narrow | Just right |
|---|---|---|
| "Sports are good." | "Sachin Tendulkar scored 100 centuries." | "Regular physical activity improves both mental and physical health in students." |
The PEEL Model in Detail
P — Point (Topic Sentence)
State the main idea of the paragraph clearly. "Access to clean water is essential for good health."
E — Evidence
Provide a fact, statistic, or specific example that supports your point. "According to the World Health Organisation, over 2 billion people worldwide lack access to safe drinking water."
E — Explanation
Explain HOW or WHY the evidence supports your point. This is the most important step — many students skip it. "Without safe water, diseases like cholera, typhoid, and dysentery spread rapidly, particularly affecting children under five. This leads to school absenteeism and reduced learning outcomes."
L — Link
Connect back to the main idea or lead into the next paragraph. "It is clear that solving the water crisis is not just a health issue but an educational and economic priority."
Coherence vs Cohesion
| Term | Meaning | How to achieve |
|---|---|---|
| Coherence | The paragraph makes logical sense | Arrange ideas in order (general → specific, or cause → effect) |
| Cohesion | The sentences are grammatically linked | Use transition words, pronoun reference, and repetition of key terms |
Cohesion example — poor: "Trees provide oxygen. Deforestation is increasing. Animals lose habitat. Logging companies operate." (Four unconnected ideas — no flow)
Cohesion example — improved: "Trees are vital because they produce the oxygen we breathe. However, deforestation is increasing at an alarming rate. As a result, animals lose their natural habitat, forcing many species toward extinction. Despite this, many logging companies continue to operate with minimal restriction."
Transition Words by Function
| Function | Words to use |
|---|---|
| Introduce evidence | For example, For instance, To illustrate, Specifically |
| Add information | Furthermore, In addition, Moreover, Also |
| Show contrast | However, On the other hand, Nevertheless, Yet, Despite this |
| Show cause/effect | Therefore, As a result, Consequently, Hence, This means that |
| Sequence ideas | First, Next, Then, Subsequently, Finally |
| Summarise or link | In summary, Overall, Thus, This shows that |
Types of Paragraph Development
| Method | How it works | Best for |
|---|---|---|
| Example | Give specific instances | Explaining abstract ideas |
| Cause and Effect | Show what leads to what | Science/social issues |
| Comparison and Contrast | Show similarities and differences | Two topics or options |
| Definition | Define and explain a term | Technical or complex concepts |
| Descriptive | Use sensory details | People, places, events |
Worked Full Paragraph (PEEL)
Topic: The importance of sleep for students
P: Adequate sleep is a critical but often overlooked factor in academic performance. E: Research by the National Sleep Foundation shows that teenagers need 8–10 hours of sleep per night, yet surveys find most get fewer than 7. E: Sleep deprivation impairs memory consolidation, meaning information studied before bedtime is not properly stored. Students who sleep less are more likely to struggle with recall during exams and to show reduced attention in class. L: Schools and parents should therefore treat sleep as seriously as study time, since rest is not the opposite of productivity — it enables it.
