What you will be able to do

  • Name a passage's dominant purpose: inform, persuade, entertain, describe, or explain.
  • Use tone, especially satire, sarcasm, or irony, to identify an author's purpose.
  • Check that a piece of evidence actually serves the purpose you identified.

What the lesson concludes

  • Name the dominant purpose first: inform, persuade, entertain, describe, or explain.
  • Tone, especially satire, sarcasm, or irony, is often the fastest clue to purpose.
  • Persuasive writing leans on emotional appeals and opinion. Informative writing leans on citable facts.
  • Check that any evidence a question points to actually serves the purpose you identified.
  • A passage can blend purposes, but one is usually doing most of the work. Find it first.
