This document defines and provides examples of common rhetorical devices used in writing and speaking to effectively convey ideas and arguments. It discusses repetition, parallelism, and rhetorical questions. Repetition and parallelism use repeated words or structures to provide rhythm and emphasis. Rhetorical questions are posed to prompt thought rather than being answered literally. Examples are provided to illustrate parallelism in Julius Caesar's famous quote and rhetorical questions from a John F. Kennedy speech used to sway audiences.
