Thinking about paragraphs rigidly in terms of length may lead to formulaic writing. Instead, as you revise your draft think about how each sentence is functioning in your paragraph, and whether your paragraph has sufficient functional sentences to make its point. Transition sentences guide your reader smoothly from the topic of the preceding paragraph into the topic of your new paragraph. Writers sometimes begin with a transition sentence before introducing the topic of the new paragraph. A topic sentence states the main idea of a paragraph. Beginning a paragraph with a topic sentence ensures your reader recognizes early in the paragraph what larger idea the paragraph is going to demonstrate. Expert writers may not introduce the topic until the middle or end of the paragraph, and often imply their topics without ever writing a topic sentence. Body sentences develop the topic of the paragraph. These sentences work to analyze data or quotations, describe a text or event, set up a comparison, showcase evidence, and sometimes they enumerate the logical points for readers to give them a sense of a paper's bigger picture. In body sentences, you need to consider how much quoted data or evidence will demonstrate or prove your point. Linking sentences relate back to the paper's main argument by showing how the idea of that paragraph matches the overall goal of the paper. Concluding sentences may bring a section to its end before you move on to a new section of the paper.
