AP English Language / Rhetorical Situation
Lesson
Purpose is a verb, not a school-essay label
Writers try to do something to an audience. Name the something.
Learning goals
- Replace vague purposes with specific verbs.
- Show how the same facts can serve opposite purposes for different audiences.
Explanation
“To inform” is usually too thin. A writer may warn, invite, shame, reassure, delay, or recruit. The same statistic about water quality can reassure a city council or alarm a neighborhood, depending on what the speaker wants the audience to do next.
Persona is the voice the writer puts on for the job: neighbor, expert, skeptic, mourner. It is not a lie just because it is chosen. It becomes a problem when the mask hides a conflict of interest the audience would want to know.
Key terms
- Purpose. The change in belief, feeling, or action the writer wants from the audience.
- Persona. The speaking role a writer adopts for a particular audience and occasion.
Common mistakes
- Stopping at “the author wants to get the reader’s attention.”
- Confusing the writer’s biography with the persona on the page.
Practice
Original Marlow Works items. Check the answer explanation after you try.
A city engineer writes an open letter to residents arguing that a proposed bike lane will "cut crash injuries on this corridor, not just add paint to the curb." The phrase most clearly functions to do which of the following?
Original Marlow Works item — not a College Board question.
Take your time—this is practice, not a test.
Answer explanation
Rewrite this purpose so it is usable: “The author wrote this to inform people about recycling.”
Answer. Something like: “The author wants apartment residents to start using the building’s new sorting bins this month.”
A usable purpose names an audience and a next action or belief.
