Paragraphs usually begin with a topic sentence or a transition sentence. The start of a paragraph often depends on the type of work being written.
The paragraphs in academic papers often follow a traditional format that includes general information sentences, including the topic sentence; body sentences that develop the idea; and concluding sentences. It is important to recognize the difference between topic sentences in paragraphs, which describe the purpose of the specific paragraph itself, and theses statements, which provide an overview of the entire paper or article.
Narrative paragraphs tend to take on a less formal structure but still require formatting. Such paragraphs often open with an introduction and include information about the setting, location and action.
