adj. done or said without preparation; spontaneous
n. a speech, performance, or action done without preparation

- promptu (from Latin "promptus," meaning "ready" or "prepared")
Etymology Origin:
The word "impromptu" originates from the Latin phrase "in promptu," meaning "in readiness." Over time, it evolved in French as "impromptu," retaining the sense of something done without prior preparation. The prefix "im-" negates "promptu," emphasizing spontaneity. The term was adopted into English in the 17th century, initially in musical contexts (unrehearsed performances) before broadening to general use.
