Impromptu was adopted directly from Latin, where it literally meant “in readiness.” In English its meaning changed to “spontaneous.”
Etymology
From French impromptu, from Latin in promptu ('in readiness, at hand'), from the ablative of promptus ('readiness'), from promere ('to bring forth'), from pro- ('forth') + emere ('to take').
