Origin & History of “pulley”
Although pulleys are used for ‘pulling’, there is no etymological connection between the two words. Pulley comes via Old French polie from vulgar Latin *polidia, which was probably borrowed from the plural of a medieval Greek *polidion, a diminutive form of Greek pólos ‘pole, pivot’ (source of English pole ‘extremity’).
