Writing Effective Topic Sentences

A topic sentence is the first sentence of a paragraph that introduces the main idea and sets the direction for the rest of the paragraph. Follow these guidelines to create effective topic sentences:

1. Identify the main idea

Determine the central point or theme of your paragraph by asking yourself, “What is this paragraph about?”

2. Make it specific

Focus on a single, specific idea that will be discussed in the paragraph

3. Keep it concise

Avoid unnecessary details or information that will be covered later in the paragraph

4. Provide direction

Use the topic sentence to guide the reader and set expectations for what will be discussed. The rest of the paragraph should support, explain, or elaborate on the main idea introduced in the topic sentence

5. Engage the reader

When appropriate, use interesting or thought-provoking statements to capture the reader’s attention. Create a hook statement by considering using a question, quote, or surprising fact to draw the reader in

6. Connect to the thesis or central argument

Ensure that your topic sentence relates to the overall thesis or central argument of your essay. Each topic sentence should contribute to the development of your main point
