【中文词源】：

来自古法语polie,滑轮，来自拉丁语poliva,来自希腊语polos,轮轴，滑轮，来自PIE*kwel,轮，词源同pole,两极，地轴。

【英语词源】：

pulley: [14] 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’).
