This document defines and explains satire. Satire uses ridicule and irony to criticize and argue for reform of societal ills. It aims to be constructive, not just destructive. There are two main types: Horatian satire, which uses gentle humor, and Juvenalian satire, which is more abrasive and angry. Satire employs personas rather than expressing the author's real views. When analyzing a satirical work, one should consider what is being satirized, what methods are used, and whether the tone is Horatian or Juvenalian.
