Entries linking to windpipe
wind n.1
"air in motion," Old English wind "wind," from Proto-Germanic *winda- (source also of Old Saxon, Old Frisian, Middle Dutch, Dutch wind, Old Norse vindr, Old High German wind, German Wind, Gothic winds), from PIE *wē-nt-o‑ "blowing," suffixed (participial) form of root *we- "to blow."
Normal pronunciation evolution made this word rhyme with kind and rind (Donne rhymes it with mind and Thomas Moore with behind), but it shifted to a short vowel 18c., probably from influence of windy, where the short vowel is natural. A sad loss for poets, who now must rhyme it only with sinned and a handful of weak words. Symbolic of emptiness and vanity since late 13c.
I have forgot much, Cynara! gone with the wind. [Ernest Dowson, 1896]
Meaning "breath" is attested from late Old English; especially "breath in speaking" (early 14c.), so long-winded, also "easy or regular breathing" (early 14c.), hence second wind in the figurative sense (by 1830), an image from the sport of hunting.
Winds "wind instruments of an orchestra" is from 1876. Figurative phrase which way the wind blows for "the current state of affairs" is suggested from c. 1400. To get wind of "receive information about" is by 1809, perhaps inspired by French avoir le vent de. To take the wind out of (one's) sails in the figurative sense (by 1883) is an image from sailing, where a ship without wind can make no progress. Wind-chill index is recorded from 1939. Wind energy from 1976. Wind vane from 1725.
pipe n.1
Old English pipe "simple tubular musical wind instrument," also "tube for conveying water," from Vulgar Latin *pipa "a pipe, tube-shaped musical instrument" (source also 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 the tubular senses ultimately derive from the meaning "small reed, whistle." From late 14c. as "a tube or duct of the body." From mid-15c. as "one of the tubes from which the tones of an organ are produced." Meaning "narrow tubular device for smoking" is recorded by 1590s. As "the sound of the voice," 1570s.
Pipe-bomb, "home-made bomb contained in a metal pipe," is attested from 1960. Pipe-cleaner, "piece of wire coated with tufted material," is recorded from 1863. Pipe-clay "white clay suitable for making smoking pipes" is attested by 1777.
