To make a hopeless effort to save oneself. The term comes from the ancient image of a drowning man clutching at insubstantial reeds in an attempt to save himself, and it often was put as to catch or clutch at straws. It appeared in print as early as the sixteenth century and soon was regarded as a proverb. Indeed, Samuel Richardson so identifies it in Clarissa (1748): “A drowning man will catch at a straw, the proverb well says.” An earlier usage is “We do not as men redie to be drowned, catch at euery straw” (John Prime, Fruitful and Brief Discourse, 1583).
