A pulley is a wheel with a groove that a rope or chain runs over, used to lift heavy things more easily. You pull the rope, the wheel turns, and the load comes up. Several pulleys together — a block and tackle — let you lift more than you could with your arms alone. Ships, building sites, gym machines, and physics class all use them. You can also pulley something as a verb, though the noun is far more common. It looks as if it must come from pull, and people have long thought so, because that is what you do with the rope. Though actually, that is a folk story. The word came from Old French poulie, from a medieval Latin form of Greek ídion, “little pivot,” a diminutive of pólos, a pivot, hinge, or axis — the same Greek idea as the earth’s . The pull in your hands and the pull in the spelling just happened to meet.
組成From Middle English puly, poley, from Old French poulie, polie (“a pulley, windlass”), from Medieval Latin polidia, from Ancient Greek πολίδιον (polídion, “little pivot”), diminutive of πόλος (pólos, “pivot, hinge, axis”). Associated with the verb pull by folk etymology, not by true origin.
