This question is a prevalent one in writing circles. How should a person craft this elusive “topic sentence?” I have compiled a short note on the topic sentence, which should answer the question above. I hope all readers can use this note in their CXC prep/ CSEC prep to be successful in their exams. The note on topic sentences is found below.

A topic sentence is the first sentence of a paragraph and introduces the main idea that the paragraph will discuss.

It should be clear, concise, and directly related to the thesis statement of the essay.

To write an effective topic sentence, identify the specific point you want to make in that paragraph. Avoid vague or overly broad statements—be specific enough to guide the reader while leaving room for supporting details.

A good topic sentence acts like a mini thesis for the paragraph, setting the tone and direction for the information that follows.

For example, if your essay is about the benefits of exercise, a strong topic sentence might be: “Regular physical activity improves mental health by reducing stress and anxiety.”

After writing your topic sentence, ensure the rest of the paragraph supports it with facts, examples, or analysis. Revising your topic sentences as you develop your ideas can also improve clarity and focus.

Below are five sample topic sentences.

1. Education
   “Hands-on learning activities help students better retain information and stay engaged in the classroom.”
2. Technology
   “The rise of smartphone use has drastically changed how people interact in both personal and professional settings.”
3. Health
   “Eating a balanced diet plays a crucial role in maintaining long-term physical and mental health.”
4. Environment
   “Plastic pollution in the ocean poses a serious threat to marine life and the health of global ecosystems.”
5. Social Media
   “Social media platforms can create unrealistic standards that negatively affect users’ self-esteem and body image.”

I hope that this note clarified how one should write a topic sentence.
