usury: [14] Usury is etymologically ‘use’ of money lent. The term comes via Anglo-Norman *usurie from medieval Latin ūsūria, an alteration of classical Latin ūsūra ‘use of money lent’, hence ‘interest’. This in turn was derived from ūsus ‘use’, source also of English use and usage. => use[usury etymology, usury origin, 英语词源]
