magic: [14] Greek mágos, a word of Persian origin, meant ‘sorcerer’ (Latin borrowed it as magus, whose plural magi is used in English for the three ‘Wise Men’ who visited the infant Christ). From mágos was derived the adjective magikós. Its use in the phrase magiké tékhnē ‘sorcerer’s art’ led eventually to magiké itself being regarded as a noun, and it passed into English via late Latin magica and Old French magique. => magi[magic etymology, magic origin, 英语词源]
