1. improvised

   Extemporaneous, originally signifying of or from the time or occasion, has come to mean done or made with but little (if any) preparation, and is now chiefly applied to addresses of which the thought has been prepared, and only the language and incidental treatment left to the suggestion of the moment, so that an extemporaneous speech is understood to be any one that is not read or recited; impromptu keeps its original sense, denoting something that springs from the instant; the impromptu utterance is generally brief, direct, and vigorous; the extemporaneous speech may chance to be prosy. Offhand is still more emphatic as to the readiness and freedom of the utterance. Unpremeditated is graver and more formal, denoting absolute want of preparation, but is rather too heavy a word to be applied to such apt, ready utterance as is generally designated by impromptu.

   Antonyms:
   elaborated, premeditated, prepared, read, recited, studied, written

   Synonyms:
   extemporaneous, extemporary, extempore, impromptu, offhand, unpremeditated
