editEtymology
editFrom Middle English puly, poley, from Old French poulie, polie (“a pulley, windlass”), from Medieval Latin polidia, plural mistaken for the feminine of neuter polidium, from Ancient Greek πολίδιον (polídion, “little pivot”), diminutive of πόλος (pólos, “pivot, hinge, axis”), from Proto-Indo-European *kʷel- (“to turn”). Associated with pull (verb) by folk etymology.
