adverb: [15] Adverb comes ultimately from a Latin word modelled on Greek epírrhēma, literally ‘added word’. The elements of this compound (the prefix epi- and rhēma ‘word’) were translated literally into Latin (ad- and verbum), giving adverbum. English took the word either directly from Latin, or via French adverbe. => verb[adverb etymology, adverb origin, 英语词源]
