as a music form featuring flatted thirds and sevenths, possibly c.1895 (though officially 1912, in W.C. Handy’s “Memphis Blues”); meaning “depression, low spirits” goes back to 1741, from adjectival blue “low-spirited,” late 14c.
c.1300, bleu, blwe, etc., from Old French blo “pale, pallid, wan, light-colored; blond; discolored; blue, blue-gray,” from Frankish *blao or some other Germanic source, from Proto-Germanic *blæwaz (cf. Old English blaw, Old Saxon and Old High German blao, Danish blaa, Swedish blå, Old Frisian blau, Middle Dutch bla, Dutch blauw, German blau “blue”), from PIE *bhle-was “light-colored, blue, blond, yellow,” from PIE root bhel- (1) “to shine, flash” (see bleach (v.)).
The same PIE root yielded Latin flavus “yellow,” Old Spanish blavo “yellowish-gray,” Greek phalos “white,” Welsh blawr “gray,” Old Norse bla “livid” (the meaning in black and blue), showing the usual slippery definition of color words in Indo-European The present spelling is since 16c., from French influence (Modern French bleu).
The exact color to which the Gmc. term applies varies in the older dialects; M.H.G. bla is also ‘yellow,’ whereas the Scandinavian words may refer esp. to a deep, swarthy black, e.g. O.N. blamaðr, N.Icel. blamaður ‘Negro’ [Buck]
Few words enter more largely into the composition of slang, and colloquialisms bordering on slang, than does the word BLUE. Expressive alike of the utmost contempt, as of all that men hold dearest and love best, its manifold combinations, in ever varying shades of meaning, greet the philologist at every turn. [John S. Farmer, “Slang and Its Analogues Past and Present,” 1890, p.252]
The color of constancy since Chaucer at least, but apparently for no deeper reason than the rhyme in true blue (c.1500). From early times blue was the distinctive color of the dress of servants, which may be the reason police uniforms are blue, a tradition Farmer dates to Elizabethan times. For blue ribbon see cordon bleu under cordon. Blue whale attested from 1851, so called for its color. The flower name blue bell is recorded by 1570s. Blue streak, of something resembling a blt of lightning (for quickness, intensity, etc.) is from 1830, U.S. Western slang.
Many Indo-European languages seem to have had a word to describe the color of the sea, encompasing blue and green and gray; e.g. Irish glass (see Chloe); Old English hæwen “blue, gray,” related to har (see hoar); Serbo-Croatian sinji “gray-blue, sea-green;” Lithuanian šyvas, Russian sivyj “gray.”
“lewd, indecent” recorded from 1840 (in form blueness, in an essay of Carlyle’s); the sense connection is unclear, and is opposite to that in blue laws (q.v.). John Mactaggart’s “Scottish Gallovidian Encyclopedia” (1824) containing odd words he had learned while growing up in Galloway and elsewhere in Scotland, has an entry for Thread o’Blue, “any little smutty touch in song-singing, chatting, or piece of writing.” Farmer [“Slang and Its Analogues Past and Present,” 1890] offers the theory that this meaning derives from the blue dress uniforms issued to harlots in houses of correction, but he writes that the earlier slang authority John Camden Hotten “suggests it as coming from the French Bibliothèque Bleu, a series of books of very questionable character,” and adds, from Hotten, that, “Books or conversation of an entirely opposite nature are said to be Brown or Quakerish, i.e., serious, grave, decent.”
“to make blue,” c.1600, from blue (1).
A kind of jazz that evolved from the music of African-Americans, especially work songs and spirituals (see also spirituals), in the early twentieth century. Blues pieces often express worry or depression.
