What does extemporized mean?
"Extemporized" is the past tense of the verb "extemporize," meaning to compose, perform, or deliver something on the spur of the moment, without a script, score, or rehearsal. A speaker who loses their notes may extemporize a talk; a musician may extemporize a solo or variation. The word carries connotations of fluency and quick wit — extemporizing well implies genuine mastery, since the performer must draw entirely on knowledge and instinct rather than preparation. It derives from the Latin phrase ex tempore, "out of the moment," the same root that gives us "temporary" and "contemporary." Though closely allied with "improvise," it retains a slightly formal flavor, appearing most often in discussions of rhetoric, classical music, and jazz. British English favors the spelling "extemporised." For anyone describing unscripted eloquence — whether at a podium, a piano, or a pulpit — "extemporized" remains the precise, distinguished choice.

Etymology of extemporized
Extemporized traces back through the verb "extemporize" to the Latin phrase ex tempore, literally "from the time," i.e., on the spur of the moment. Medieval Latin developed the adjective extemporaneus, "unpremeditated," which passed into English around the early seventeenth century alongside related forms such as "extempore" and "extemporaneous." The same Latin root tempus (time) also yields "temporary," "temporal," and "contemporary." The verb came to be applied particularly to unscripted speaking and to spontaneous musical invention, senses it has retained into modern English.
