The topic sentence typically appears at the beginning of a paragraph. It introduces the main idea or point that the paragraph will discuss.
Here's why it's crucial to place the topic sentence at the start:
- Clarity: It sets the stage for the reader, providing a clear understanding of what the paragraph will cover.
- Organization: It acts as a guide, helping the reader follow the flow of ideas within the paragraph.
- Focus: It ensures that the paragraph stays on track and avoids irrelevant information.
Examples:
-
Paragraph 1:
- Topic Sentence: The invention of the printing press revolutionized communication and knowledge dissemination.
- Supporting Sentences: Before the printing press, books were painstakingly copied by hand, making them expensive and rare. The printing press allowed for mass production of books, making them more affordable and accessible to a wider audience. This led to a surge in literacy and the spread of new ideas.

Paragraph 2:
- Topic Sentence: Climate change poses a significant threat to biodiversity and ecosystems worldwide.
- Supporting Sentences: Rising temperatures and extreme weather events disrupt natural habitats. Ocean acidification harms marine life. Habitat loss and fragmentation make species more vulnerable.
It's important to note that while the topic sentence is usually at the beginning, it can occasionally appear in other positions for stylistic purposes, such as at the end of a paragraph for emphasis.
