Did You Know?

Adjective

If you think that "impromptu" looks like a relative of "prompt," you're right; both are ultimately derived from the Latin promere, meaning "to bring forth, take out." "Impromptu" was borrowed from French, where it meant "extemporaneously," but French speakers picked it up from the Latin phrase in promptu, a "promere" descendant meaning "in readiness" or "at hand." There is also another, much rarer descendant of "promere" in English - the noun promptuary, meaning "a book of ready reference."
