Parallelism, also known as parallel structure or parallel construction, is a balance within one or more sentences of similar phrases or clauses that have the same grammatical structure. The application of parallelism improves writing style and readability, and is thought to make sentences easier to process. Parallelism examples are found in literary works as well as in ordinary conversations.
This method adds balance and rhythm to sentences giving ideas a smoother flow and thus can be persuasive because of the repetition it employs.
Example:
“Alice ran into the room, into the garden, and into our hearts.” (We see the repetition of a phrase that not only gives the sentence a balance but rhythm and flow as well.)
This repetition can also occur in similar structured clauses e.g. “Whenever you need me, wherever you need me, I will be there for you.”
