Evaluating Sentences for Parallelism Using parallel language means that you apply a consistent grammatical pattern across a sentence or paragraph. Parallelism is most important when you use series or lists. For example, when you describe a product with three characteristics, use the same grammatical pattern for each—that is, for example, choose the same combination and form of verbs, adjectives, and/or nouns. When you use consistent grammatical patterns for items in lists and series, readers can process the information far more naturally and quickly. In this exercise, you will evaluate whether sentences are parallel. By applying parallelism to your writing, you help your readers understand your messages more easily and more quickly.
