What does extemporised mean?
Extemporised means done, spoken, or performed without preparation in advance. It is especially associated with speech, music, comedy, and other forms of live performance: an extemporised speech is delivered on the spur of the moment, while an extemporised performance is created without a prepared script or score. The word may also function as the past participle of extemporise, as in “the minister extemporised a response.” Although its meaning overlaps with improvised, impromptu, and spontaneous, extemporised often carries a slightly literary or formal tone. It can also carry the implication that the speaker or performer responded effectively to the circumstances rather than merely lacking preparation. The word is useful because it describes a familiar form of skilled improvisation: turning an unplanned moment into articulate words, music, or action. Its British -ised spelling is also understood in American English, where the spelling extemporized is standard.

Where does extemporised come from?
Extemporised derives from extemporise, a verb formed in the early 17th century from the Latin phrase ex tempore, literally “out of time” and idiomatically “on the occasion.” The development reflects the idea of speaking or acting immediately, without advance preparation. The same Latin root underlies words such as temporary and contemporary, while related forms appeared in European languages, including French extemporiser and Spanish extemporáneo.
