The definition of a paragraph is varied. According to Pensri Rangsiyakool (2006: 76), a paragraph is a group of related statements a writer develops about a subject. The first sentence states the specific point, or idea of the topic. The rest of the sentences in the paragraph support that point, or idea. Moreover, Dewhurst (n.d.) states that a paragraph is a basic unit of organization in writing in which a group of relevant sentences develops one main idea. It can be as short as one sentence but it is normally longer than or as long as ten sentences but it is usually shorter. However, it should be long enough to develop the main idea clearly, but not so long that the paragraph loses its focus. Hence, a paragraph is a primary unit of composition writing that is formed by many sentences to convey the writer’s ideas. In addition, a paragraph encompasses three rhetorical patterns: topic sentence, supporting sentences, and conclusion.
