1911 Encyclopædia Britannica (1911)
“ IMPROVISATORE, a word used to describe a poet who recites verses which he composes on the spur of the moment, without previous preparation. The term is purely Italian, although in that language it would be more correctly spelt improvvisatore. It became recognized as an English word in the middle of the eighteenth century, and is so used by Smollett in his Travels (1766) ; he defines an improvisatore as “an individual who has the surprising talent of reciting verses extempore, on any subject you propose.” In speaking of a woman, the female form improvisatrice is sometimes used in English. ”
