What does extemporize mean?
Extemporize is a verb meaning to compose or deliver something — most often a speech, remark, or piece of music — spontaneously, without preparation, rehearsal, or a script. A politician forced to extemporize after losing her notes, or a jazz musician who begins to extemporize over a familiar chord progression, is inventing the material on the spot. The word derives from the Latin phrase ex tempore, meaning 'out of the moment' or 'on the spur of the moment,' and entered English in the early seventeenth century alongside related forms such as extempore and extemporaneous. In register it leans formal: writers about rhetoric, debate, and music favor it, while everyday conversation tends toward 'improvise' or 'ad-lib.' Its connotations are largely neutral to admiring, since successful extemporizing implies fluency and quickness of mind, though it can subtly suggest that a speaker arrived unprepared. The noun form is extemporization, and an extemporizer is someone skilled at speaking or playing off the cuff.

Etymology of extemporize
Extemporize comes from the Medieval Latin adjective extemporaneus, formed from the Latin phrase ex tempore, literally 'out of the time' or 'out of the moment,' which describes something done on the spur of the moment. English adopted the verb in the early seventeenth century, around the same period it absorbed related borrowings such as extempore and extemporaneous. The same Latin root tempus ('time') underlies a broader family of English words, including temporary, contemporary, and temporize, all of which concern timing, duration, or the present moment.
