impromptu
im-PROMP-too
/ɪmˈprɒmptjuː/
Done without being planned, organized, or rehearsed.
Highlights the spontaneous, spur-of-the-moment nature of an event, often relying on quick thinking and whatever is available.
The story behind the word. From French, which adapted the Latin phrase 'in promptu' ('in readiness, at hand'), from 'promere' ('to bring forth'). It describes something done on the spot because the resources or ideas are already 'at hand'.
