In grammar, parallelism is a balance of two or more similar words, phrases, or clauses. The application of parallelism in sentence construction improves writing style and readability. Parallelism may also be known as parallel structure or parallel construction. In English, parallelism of the predicate provides for one of the few structural situations in which the subject for each verb does not need restatement. Parallelism is often achieved in conjunction with other stylistic principles, such as antithesis, anaphora, asyndeton, climax, epistrophe, and symploce.[1]
Focusing Sentences Through Parallelism
________________________________________
Parallel structures include word or phrase patterns that are similar. When ideas in a sentence or paragraph are similar, you can reinforce these similarities in meaning through creating parallel structures. Effective parallelism creates symmetry in sentences and adds force to your writing; it emphasizes the likeness between two or more ideas.

Correct Form for Parallel Structures:
The first sentence below contains parallel structures; the second does not.
The Writing Center needs tutors who are ambitious, who are self-motivated, and who are dedicated.
The Writing Center needs tutors who are ambitious, motivate themselves, and exhibit dedication.
In the first example, the words "who are" are repeated three times, forcing the words "ambitious," "self-motivated," and "dedicated" to be alike. In the second example, "who are" makes sense with "ambitious," but "are" must be dropped for a reader to make sense of the following phrases in the sentence. When sentences are truly parallel, and the verbs are used exactly the same in each phrase, they do not need to be repeated.
Repeating the verbs becomes a question of style and emphasis. Don't go too far with parallelism! Sentence 1 above could also be stated, without too much repetition:
The Writing Center needs tutors who are ambitious, self-motivated, and dedicated.
