late 14c., "fierce passion," from Old French furie (14c.), from Latin furia "violent passion, rage, madness," related to furere "to rage, be mad." Romans used Furiæ to translate Greek Erinyes, the collective name for the avenging deities sent from Tartarus to punish criminals (in later accounts three in number and female). Hence, figuratively, "an angry woman" (late 14c.).
