A topic sentence is the main sentence in a paragraph that tells the reader what the paragraph is about. It gives the central idea and sets the tone for the rest of the sentences.
The topic sentence is often the first sentence in the paragraph, but it can also appear later if it makes sense for the paragraph.
The topic sentence helps readers understand the main idea. It keeps the writer focused and guides the supporting details.
A clear topic sentence makes a paragraph easier to read and understand. It connects all the sentences together with one main idea.
A strong topic sentence is clear, focused, and not too broad or too narrow. It should introduce the main idea without listing every detail.
Ask yourself: Can I support this sentence with 3–4 details? If yes, it is probably a strong topic sentence.
Most topic sentences are at the beginning of a paragraph, but they can also appear at the end or in the middle, depending on the style of writing.
Beginning with the topic sentence is most common in school writing, especially when learning how to organize paragraphs.
To get better at recognizing topic sentences, practice reading paragraphs and asking yourself, “What is the main idea?” Then try writing your own topic sentences for practice topics.
Good writers always think about the main idea first. A strong topic sentence makes the rest of the writing clear and connected. (Aligned with the USA Common Core Curriculum)
