charm: [13] Although now largely weakened to mere ‘attractiveness’, the origins of charm are in magic spells and incantations. It comes via Old French charme from Latin carmen ‘song’, which was also used for the chanting or reciting of verses with supposedly magic powers. Thus in the Middle Ages, charms were synonymous with enchantment – either spoken or, in more concrete form, carried as talismans. The latter have degenerated in modern times to small trinkets worn on bracelets, an application first recorded in the mid 19th century. [charm etymology, charm origin, 英语词源]
