What does a paragraph consist of?

A paragraph is fundamentally defined as a cohesive structure made up of multiple sentences that revolve around a single main idea or topic. The primary purpose of a paragraph is to convey a specific point or argument, which is typically encapsulated in a topic sentence, followed by supporting sentences that elaborate on or reinforce that main idea. This organization helps in guiding the reader through the text and enhances clarity and understanding.

By focusing on a singular theme or topic, the sentences within the paragraph work together to create a unified message. This cohesion is essential for effective communication in writing, ensuring that readers can easily grasp the intended meaning without confusion or distraction from unrelated ideas.
