charm [charm 词源字典]: 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]
ferrule (n.): "metal cap on a rod," 1610s, ferule, earlier verrel (early 15c.), from Old French virelle "ferrule, collar" (12c. Modern French virole), from Medieval Latin viriola "bracelet," diminutive of Latin viriae "bracelets," from a Gaulish word akin to Old Irish fiar "bent, crooked," from PIE *wi-ria-, from root *wei- (1) "to turn, twist" (see wire (n.)). Spelling influenced by Latin ferrum "iron."
veer (v.): 1580s, "to change direction" (originally of the wind; 1610s of a ship), from Middle French virer "to turn" (12c.), of uncertain origin, perhaps (Diez) from the Latin stem vir- in viriae (plural) "bracelets." Gamillscheg finds von Wartburg's derivation of it from a Vulgar Latin contraction of Latin vibrare "to shake" to be nicht möglich. Related: veered, veering.
wire (n.): Old English wir "metal drawn out into a fine thread," from Proto-Germanic *wira- (cognates: Old Norse viravirka "filigree work," Swedish vira "to twist," Old High German wiara "fine gold work"), from PIE *wei- (1) "to turn, twist, plait" (cognates: Old Irish fiar, Welsh gwyr "bent, crooked;" Latin viere "to bend, twist," viriæ "bracelets," of Celtic origin). A wire as marking the finish line of a racecourse is attested from 1883; hence the figurative down to the wire. Wire-puller in the political sense is 1848, American English, on the image of pulling the wires that work a puppet.
