mellifluous

Etymology

It is borrowed from Late Latin mellifluus (“flowing with honey, sweet as honey”),^{[2][3][4][5][6]} with the suffix -ous.^[2][5] Hoad and the Shorter Oxford also allow Old French melliflue as a source beside the Latin adjective,^[7][8] and the OED compares the earlier English adjective melliflue.^[2] The Latin adjective, recorded from the late 4th century,^[2] is formed from Latin mel (“honey”) and -fluus (“flowing”), from fluō (“to flow”), the verb behind fluent.^[2][3][4] The noun goes back to Proto-Indo-European *melit- (“honey”),^[3][9] and it is cognate with Ancient Greek μέλι (méli), Old Irish mil, Welsh mel, Gothic 𐌼𐌹𐌻𐌹𐌸 (miliþ) and Hittite milit,^[5][4] and akin to Old English milisc (“sweet”) and mildēaw (“honeydew”), the source of mildew.^[4] The American Heritage Dictionary takes the second part from Proto-Indo-European *bhleu-.^[9] The OED compares Ancient Greek μελίρρυτος (melírrhutos, “flowing with honey”).^[2]

Earliest recorded meaning

Sweet as honey, literally and of style: perhaps before 1475 (the text perhaps before 1425), in a translation of Higden's Polychronicon, which speaks of writers mixing a profitable thing "with a swetenesse mellifluous".^[6][2] Barnhart and Etymonline date the word by the text's earlier date,^[5][3] and the Oxford Dictionary of English gives the late 15th century.^[10]

Semantic evolution

The Middle English Dictionary records it of a sweet smell, of a pleasing style and of the comforting teaching of Christ.^[6] The OED's literal sense, flowing with or containing honey, is now rare,^[2] while the transfer to speech and music, present from the first record, became the main meaning.^[2][8] By 1483, in Caxton's Golden Legende, it could describe a speaker: the phrase the mellifluous doctor follows the Latin title mellifluus doctor given to St Bernard, a Latin use found from at least the mid 14th century.^[2] Later the sense "smoothly eloquent, charmingly persuasive" developed.^[2] Johnson (1755) gave "flowing with honey; flowing with sweetness" and quoted Shakespeare's "a mellifluous voice".^[11] Today Collins limits it to sounds and utterances.^[12] Beside it English took mellifluent in 1601.^[5]

Usage notes

Mellow looks as if it belongs with this word, but the Oxford Dictionary of Word Origins says it is unrelated and may come from Old English melu, meal.^[13]
