What is the meaning of the word precipitous?

The term "precipitous" refers to something that is very steep, sudden, or characterized by a rapid change. In this context, "abrupt" aligns perfectly with the meaning of "precipitous," as both describe a scenario where there is a quick or steep transition or drop, whether in terrain or in situations like decisions or changes in emotion.

The other choices do not convey the steepness or suddenness implied by "precipitous." "Cautious" suggests carefulness and deliberation, "languid" refers to a state of weakness or fatigue, and "subtle" indicates something that is delicate or understated. None of these options reflect the essence of abruptness or steepness that is central to the meaning of "precipitous."
