What is the meaning of "extempore"?

The meaning of "extempore" refers to actions, speeches, or performances conducted without prior preparation or forethought. This term is often used in contexts such as public speaking or theater, where an individual may present their thoughts spontaneously, relying on their knowledge and skills in the moment. The essence of extempore is the ability to think and respond quickly without a scripted plan, highlighting improvisation and adaptability.

In contrast, the other options pertain to different concepts: relieving of blame refers to exoneration; lessening the importance implies diminishing significance; and making amends relates to reconciliation or compensation. Each of these concepts captures a distinct action that does not align with the spontaneous nature described by "extempore." Therefore, the correct choice emphasizes the unprepared aspect inherent in the term.
