Old English pipe "musical wind instrument," also "tube to convey water," from Vulgar Latin *pipa "a pipe, tube-shaped musical instrument" (source of Italian pipa, French pipe, Old Frisian pipe, German Pfeife, Danish pibe, Swedish pipa, Dutch pijp), a back-formation from Latin pipare "to chirp or peep," of imitative origin. All tubular senses ultimately derive from "small reed, whistle." Meaning "device for smoking" first recorded 1590s. Pipe-bomb attested from 1960. Pipe-cleaner recorded from 1863.
type of cask, early 14c., from Old French pipe "liquid measure, cask for wine," from a special use of Vulgar Latin *pipa "pipe" (see pipe (n.1)).
Old English pipian "to play on a pipe," from Latin pipare "to peep, chirp" (see pipe (n.1)). Cf. Dutch pijpen, German pfeifen. Meaning "convey through pipes" is first recorded 1887. Related: Piped; piping. Piping hot is in Chaucer, a reference to hissing of food in a frying pan; to pipe up (early 15c.) originally meant "to begin to play" (on a musical instrument); sense of "to speak out" is from 1856. Pipe down "be quiet" is from 1900; earlier in nautical jargon it meant "use a boatswain's whistle to dismiss the men from duty" (1833).
[1902+ Students; apparently fr pipe dream, suggesting something as easily or magically done as in a wishful dream]
[all senses probably derived fr pipe as a conduit or a musical instrument; the sense ''look at'' is related to criminal slang ''follow, keep under surveillance,'' of obscure origin and difficult to relate to any sense of pipe; pipe-gun, ''crude gun made of a pipe,'' is found by 1973]
(1 Sam. 10:5; 1 Kings 1:40; Isa. 5:12; 30:29). The Hebrew word halil, so rendered, means "bored through," and is the name given to various kinds of wind instruments, as the fife, flute, Pan-pipes, etc. In Amos 6:5 this word is rendered "instrument of music." This instrument is mentioned also in the New Testament (Matt. 11:17; 1 Cor. 14:7). It is still used in Palestine, and is, as in ancient times, made of different materials, as reed, copper, bronze, etc.
