livery (n.)youdaoicibaDictYouDict[livery 词源字典]
c. 1300, "household allowance of any kind (food, provisions, clothing) to retainers or servants," from Anglo-French livere (late 13c.), Old French livrée, "allowance, ration, pay," originally "(clothes) delivered by a master to his retinue," from fem. past participle of livrer "to dispense, deliver, hand over," from Latin liberare (see liberate). The sense later was reduced to "servants' rations" and "provender for horses" (mid-15c.). The former led to the meaning "distinctive clothing given to servants" (early 14c.); the latter now is obsolete except in livery stable (1705).
