Etymology
Origin of prompt
First recorded in 1400–50; Middle English prompte “ready, eager” (adjective), prompten (verb), both ultimately from Latin promptus “manifest, at hand, ready, quick, prepared,” adjective use of past participle of prōmere “to bring forth, deliver, set forth,” from prō- pro- 1 + (e)mere “to buy, obtain, take”
Explanation
If you're prompt, you're on time. Go ahead and be prompt to class. Also, to prompt is to inspire or make happen. Getting in trouble for being late should prompt you to get a better alarm clock. The adjective prompt can mean "as scheduled," or simply "quick." When you prompt someone, you motivate them in some way: you might offer a reminder, assistance, or even inspiration to do something. For example, honking your car horn prompts your friend to get moving, and speaking up in defense of your classmate might prompt a bully to change his ways. If a director prompts an actor who's forgotten his lines, she reminds him what comes next.
