amulet (n.)youdaoicibaDictYouDict[amulet 词源字典]
mid-15c., amalettys, from Latin amuletum (Pliny) "thing worn as a charm against spells, disease, etc.," which is of uncertain origin, perhaps related to amoliri "to avert, to carry away, remove." Not recorded again in English until c. 1600; the 15c. use may be via French.[amulet etymology, amulet origin, 英语词源]
