Meaning: To raise trivial and frivolous objection, find fault without good reason (usually followed by at or about).
Origin: In use since the 1540s, the word originates from the French caviller, meaning to mock, jest, from Latin cavillari, meaning to jeer, argue scoffingly. This, in turn, is from Latin cavilla, meaning jest, jeering, which is related to Latin calumnia, meaning slander, false accusation.
Usage: Even he could find nothing to cavil about.
