Done or said without any advance preparation, planning, or practice; made up on the spot.
From Late Latin 'extemporaneus,' formed from 'ex tempore' (out of the time/moment). First used in English during the 17th century to describe unprepared speeches or actions.
Extemporaneous speaking is actually a competitive sport—students prepare for months to perform speeches that appear completely unrehearsed, which is the ultimate irony!
