Question

extemporaneous It was once common in middle-class homes to make extemporaneous speeches, recite poetry, and give little solo song recitals after a dinner with guests. extemporaneous*

Accepted Answer

(1) Composed, performed, spoken, or done on the spur of the moment; impromptu or improvised. (2) Carefully prepared but delivered without notes. The ability to speak well extemporaneously is an important talent for politicians, especially when participating in debates. (Though it's also a good idea to have a “spin doctor” who can go out afterward and tell everyone what the candidate really meant to say.) Some people claim there's a difference between extemporaneous and impromptu, saying that an extemporaneous speech is planned beforehand but not written down, while an impromptu speech is genuinely unprepared or off-the-cuff, but today the two words are mostly used as synonyms.
