Extempore describes a poem made up or delivered on the spot, without time for careful preparation. A poet may speak extempore in response to an event, subject, or prompt, relying on quick invention rather than revision. The word can also describe a style that aims to sound spontaneous even when it has been polished later.
Example
At the wedding feast, she smiled and said:
I raise my cup to love grown bright,
Two lanterns finding one clear road,
And all the dark made warm with light.
