bilberryyoudaoicibaDictYouDict
"A small dark blue edible berry", Late 16th century: probably of Scandinavian origin; compare with Danish bøllebær. More blue from Middle English:The English blue and French bleu are ultimately the same word, which goes back to ancient Germanic and is related to the blae- in blaeberry (Middle English), a Scottish and northern English name for the bilberry (late 16th century). Blue occurs in a number of phrases, in particular those relating either to depression and melancholy or to the blue of the sky, as in out of the blue, ‘as a total surprise’. See also bolt. Something occurring once in a blue moon is something very rare.

A particularly Australian use of blue is as a humorous nickname for a red-haired person. This is first recorded in 1932, although bluey is earlier, from 1906.Depression or melancholy have always been around, but no one called these feelings the blues until the mid 18th century, although people have been feeling blue since as early as the 1580s. The blues was a contraction of blue devils, which were originally baleful demons punishing sinners. In the 18th century people fancifully imagined them to be behind depression, and later also to be the apparitions seen by alcoholics in delirium tremens. The first printed record of the name of the melancholic music style is in the ‘Memphis Blues’ of 1912, by the American musician W. C. Handy, who later set up his own music-publishing house and transcribed many traditional blues. Its later development, rhythm and blues, appeared in the 1930s.Obscene or smutty material has been known as blue since the mid 19th century. The link may be the blue gowns that prostitutes used to wear in prison, or the blue pencil traditionally used by censors.Blue-chip shares are considered to be a reliable investment, though less secure than gilt-edged stock (used since the later 19th century for government stock, and earlier to suggest excellent quality).

Some film industry sources say it was so called for being the second of the two films major studios generally made in a year, and the one cast with less headline talent and released with less promotion.
