7.3 Parallelism

Creating Parallelism Using Coordinating Conjunctions

When you connect two clauses using a coordinating conjunction (for, and, nor, but, or, yet, so), make sure that the same grammatical structure is used on each side of the conjunction. Take a look at the following example:

Faulty parallelism: When I walk the dog, I like to listen to music and talking to friendson the phone.

Correct parallelism: When I walk the dog, I like listening to music and talking to friendson the phone.

The first sentence uses two different verb forms (to listen, talking). In the second sentence, the grammatical construction on each side of the coordinating conjunction (and) is the same, creating a parallel sentence.

The same technique should be used for joining items or lists in a series:

Faulty parallelism: This committee needs to decide whether the company should reduce its workforce, cut its benefits, or lowering workers’ wages.

Correct parallelism: This committee needs to decide whether the company should reduce its workforce, cut its benefits, or lower workers’ wages.

The first sentence contains two items that use the same verb construction (reduce, cut) and a third item that uses a different verb form (lowering). The second sentence uses the same verb construction in all three items, creating a parallel structure.
