The PREP Framework

The most reliable impromptu structure is PREP: Point, Reason, Example, Point. State your main point. Give one reason it matters. Share one brief example. Restate your point. It works for almost any topic and keeps a short answer tight.

PREP mirrors natural argument structure. You make a claim, support it with evidence, illustrate it with a short story, and land it with reinforcement. The circular structure also gives you a built-in ending — preventing the common problem of rambling when you don't know how to stop.
