Author's Purpose and Tone

Understanding why an author writes and how they express their message is essential for TEAS reading comprehension. These skills help you interpret meaning beyond the literal words.

Author's Purpose

Every piece of writing has a purpose—the reason the author wrote it. The four main purposes are:

PurposeGoalCommon Formats
InformTeach facts or explainTextbooks, news articles, encyclopedias
PersuadeChange reader's opinion or behaviorEditorials, advertisements, speeches
EntertainAmuse or engage emotionallyFiction, personal essays, humor
ExpressShare feelings or personal experiencesMemoirs, journals, poetry

Note: Many texts have multiple purposes, but one is usually dominant.

Identifying Purpose

Ask yourself these questions:

  • Is the author presenting facts objectively? → Inform
  • Is the author trying to convince me of something? → Persuade
  • Is the author telling a story or being creative? → Entertain
  • Is the author sharing personal feelings? → Express

Clues to Purpose:

PurposeClues
InformFacts, statistics, neutral language, explanations
PersuadeOpinions, emotional appeals, call to action, loaded language
EntertainStory elements, humor, vivid descriptions, dialogue
ExpressFirst person ("I"), emotions, personal reflections
