Answer: Parallelism is a grammatical technique involving the use of the same or similar grammatical structures and clauses within sentence structures. In rhetoric, parallelism similarly compounds and groups together structures and clauses to provide a flow in the sentence(s).
Parallelism is often used to create a better flow to whatever sentence it is applied to. In both poetry and speeches, it is often used for emphasis, as the repetition makes it easier for what is being said to be remembered by whoever is reading or hearing it. For these same reasons, parallelism is an attractive rhetorical technique in speeches.
