Sense shifted from original meaning of "chase, hunt." Past tense form caught is rare instance of Eng. strong verb with Fr. origin, probably infl. by latch, the cognate native verb, which this word replaced. Noun meaning "that which is caught or worth catching" (especially of spouses) is from 1590s. To catch on "apprehend" is 1884, Amer.Eng. colloquial. To catch (someone's) eye is first attested 1813, in Jane Austen. Catch as catch can first attested late 14c.
