merryyoudaoicibaDictYouDict[merry 词源字典]
merry: [OE] Merry goes back to a prehistoric Germanic *murgjaz, which appears to have been derived from a base meaning ‘short’. By the time it reached Old English, as myrige, it meant ‘pleasant’ – a semantic leap perhaps inspired by the notion of ‘shortening’ time by passing it pleasantly. The modern meaning ‘jolly’ did not emerge until the 14th century. A derivative of *murgjaz was the noun *murgithō, source of English mirth [OE]; Dutch has the related merchte ‘mirth’.

quaint: [13] Quaint was once a more wholehearted term of approval than it is now. In Middle English it meant ‘clever’ or ‘finely or skilfully made’. Its current sense ‘pleasantly curious’ did not emerge until the 18th century. It comes via Old French coint from Latin cognitus ‘known’, the past participle of cognōscere ‘know’ (source of English recognize). The word’s meaning evolved in Old French via the notion of someone who ‘knows’ about something, and hence is an expert at it or is skilful in doing it.

merry (adj.)youdaoicibaDictYouDict
Old English myrge "pleasing, agreeable, pleasant, sweet; pleasantly, melodiously," from Proto-Germanic *murgijaz, which probably originally meant "short-lasting," (compare Old High German murg "short," Gothic gamaurgjan "to shorten"), from PIE *mreghu- "short" (see brief (adj.)). The only exact cognate for meaning outside English was Middle Dutch mergelijc "joyful."

Connection to "pleasure" is likely via notion of "making time fly, that which makes the time seem to pass quickly" (compare German Kurzweil "pastime," literally "a short time;" Old Norse skemta "to amuse, entertain, amuse oneself," from skamt, neuter of skammr "short"). There also was a verbal form in Old English, myrgan "be merry, rejoice." For vowel evolution, see bury (v.).
Bot vchon enle we wolde were fyf, þe mo þe myryer. [c. 1300]
The word had much wider senses in Middle English, such as "pleasant-sounding" (of animal voices), "fine" (of weather), "handsome" (of dress), "pleasant-tasting" (of herbs). Merry-bout "an incident of sexual intercourse" was low slang from 1780. Merry-begot "illegitimate" (adj.), "bastard" (n.) is from 1785. Merrie England (now frequently satirical or ironic) is 14c. meri ingland, originally in a broader sense of "bountiful, prosperous." Merry Monday was a 16c. term for "the Monday before Shrove Tuesday" (Mardi Gras).
