Sentences in a paragraph should follow some type of organization that helps them flow in a logical order. While there is no one organization that will work for every paragraph, there are some organizations that will work for many.
Developing points and ordering information in a certain way can help keep the reader centered on the focus of the paragraph. It can also help the writer create a paragraph with a clear purpose that is easy for readers to follow.
One example of logical order is to arrange the sentence in chronological order to show a sequence of events or the passing of time. Another is to arrange sentences in order of importance. This can be done by either moving from the most important point to the least important point or going the opposite way, from the least important to the most important. Another common organization is to move from a general point, getting more specific as the paragraph moves along or to move from specific to general. No matter what order is chosen, maintaining the pattern is important to keep the paragraph clear.
Logical order can also apply to flow of paragraphs within an entire document. Like the organization of a paragraph, the organization of a document should consistent.
