An expository paragraph explains something; its purpose is to help the reader understand. In order to ensure that the purpose is achieved, the writer of the paragraph may utilize a number of paragraph features and language techniques. One essential feature is logical organization. This may take a number of forms, including demonstrating cause and effect or following a chronological order. Another important feature is providing support for the explanation being made. This support may consist of examples, illustrations, statistical or expert evidence, or even appropriate anecdotes. A final critical feature is clarity of language. The paragraph may make employ language devices such as metaphors or allusions to help illustrate its points, but they must be relatively straight forward and easy to follow so that no misunderstanding of the important points will occur. By employing these kinds of features and techniques, the writer of an expository paragraph will ensure that the paragraph’s meaning is clear to the reader.
