eucharist: [14] The Greek-based eucharist corresponds to native English thanksgiving. It comes via Old French eucariste and late Latin eucharistia from Greek eukharistíā ‘gratitude’. This was a derivative of eukháristos ‘grateful’, a compound adjective formed from the prefix eu- ‘well’ and kharízesthai ‘show favour’. The verb in turn was formed from the noun kháris ‘favour, grace’ (source of English charisma [19] and probably a distant relative of yearn [OE]). => yearn[eucharist etymology, eucharist origin, 英语词源]
