Once upon a time a professor handed out a writing assignment sheet. As she walked around the room, she reminded us to be consistent with verb tense, accurate with punctuation, and remember using parallel structure.* Wait . . . what?
Parallel structure is the repetition of a grammatical pattern within a sentence. Such patterns increase the clarity of your writing, making it easier for readers to follow, understand, and remember. Even if you have not heard of parallel structure, you probably have seen it in use. In the example below, two items in the list have the same form, but one is different. To make the structure parallel, revise the forms to match.
She likes biking, hiking, and to write short stories.
She likes biking, hiking, and writing short stories.
She likes to bike, hike, and write short stories.
When you connect two or more clauses or phrases with a coordinating conjunction (for, and, or, nor, but, yet, so) or with a correlative conjunction (not only…but also, either…or, neither…nor, if…then), use parallel structure.
We went to see a movie and walking around the lake.
We went to see a movie and walk around the lake.

His cat likes not only scratching furniture but also to destroy blinds.
His cat likes not only to scratch furniture but also to destroy blinds.

When comparing two ideas, use parallel structure.
