[Shore] was a man of humour and pleasantry, and was the original inventor of the tuning-fork, an instrument which he constantly carried about him, and used to tune his lute by, and which whenever he produced it gave occasion to a pun. At a concert he would say, "I have not about me a pitch-pipe, but I have what will do as well to tune by, a pitch-fork." [Sir John Hawkins, "A General History of the Science and Practice of Music," London, 1776]

Sense of "tube, pipe" (1540s) developed in English and led to sense of "underground passage" (1660s). This sense subsequently has been borrowed into French (1878). The earlier native word for this was mine (n.). Meaning "burrow of an animal" is from 1873. Tunnel vision first recorded 1912. The amusement park tunnel of love is attested from 1911 (in reference to New York's Luna Park). The figurative light at the end of the tunnel has been seen since 1882.
The "Tunnel of Love," an attraction found at many amusement parks, has been responsible for a surprising number of proposals. In this and similar devices, couples are allowed to drift through dark or semi-dark underground caverns, usually in a boat or gondola borne on an artificial stream of water. ... Their dim interiors often give a bashful young man the opportunity to propose. ["The American Magazine," July 1922]

The change of -l- to -r- may have taken place in Portuguese India and thence been picked up in other European languages. A men's headdress in Muslim lands, it was popular in Europe and America c. 1776-1800 as a ladies' fashion. Related: Turbaned.
- turbid (adj.)
- 1620s, from Latin turbidus "muddy, full of confusion," from turbare "to confuse, bewilder," from turba "turmoil, crowd," probably from Greek tyrbe "turmoil, tumult, disorder," from PIE *(s)twer- (1) "to turn, whirl" (see storm (n.)). Related: Turbidly; turbidness.

- Old English turf, tyrf "slab of soil and grass, sod," also "surface of grassland," from Proto-Germanic *turb- (cognates: Old Norse torf, Danish tørv, Old Frisian turf, Old High German zurba, German Torf), from PIE root *drebh- "to wind, compress" (cognates: Sanskrit darbhah "tuft of grass").

Slang meaning "territory claimed by a gang" is attested from 1953 in Brooklyn, N.Y.; earlier it had a jive talk sense of "the street, the sidewalk" (1930s), which is attested in hobo use from 1899, and before that "the work and venue of a prostitute" (1860).

- Turk (n.)
- c. 1300, from French Turc, from Medieval Latin Turcus, from Byzantine Greek Tourkos, Persian turk, a national name, of unknown origin. Said to mean "strength" in Turkish. Compare Chinese tu-kin, recorded from c. 177 B.C.E. as the name of a people living south of the Altai Mountains (identified by some with the Huns). In Persian, turk, in addition to the national name, also could mean "a beautiful youth," "a barbarian," "a robber."
In English, the Ottoman sultan was the Grand Turk (late 15c.), and the Turk was used collectively for the Turkish people or for Ottoman power (late 15c.). From 14c. and especially 16c.-18c. Turk could mean "a Muslim," reflecting the Turkish political power's status in the Western mind as the Muslim nation par excellence. Hence Turkery "Islam" (1580s); turn Turk "convert to Islam."
Meaning "person of Irish descent" is first recorded 1914 in U.S., apparently originating among Irish-Americans; of unknown origin (Irish torc "boar, hog" has been suggested). Young Turk (1908) was a member of an early 20c. political group in the Ottoman Empire that sought rejuvenation of the Turkish nation. Turkish bath is attested from 1640s; Turkish delight from 1877.
- turkey (n.)
- 1540s, originally "guinea fowl" (Numida meleagris), a bird imported from Madagascar via Turkey, and called guinea fowl when brought by Portuguese traders from West Africa. The larger North American bird (Meleagris gallopavo) was domesticated by the Aztecs, introduced to Spain by conquistadors (1523) and thence to wider Europe. The word turkey first was applied to it in English 1550s because it was identified with or treated as a species of the guinea fowl, and/or because it got to the rest of Europe from Spain by way of North Africa, then under Ottoman (Turkish) rule. Indian corn was originally turkey corn or turkey wheat in English for the same reason.
The Turkish name for it is hindi, literally "Indian," probably influenced by Middle French dinde (c. 1600, contracted from poulet d'inde, literally "chicken from India," Modern French dindon), based on the then-common misconception that the New World was eastern Asia.
After the two birds were distinguished and the names differentiated, turkey was erroneously retained for the American bird, instead of the African. From the same imperfect knowledge and confusion Melagris, the ancient name of the African fowl, was unfortunately adopted by Linnæus as the generic name of the American bird. [OED]
The New World bird itself reputedly reached England by 1524 at the earliest estimate, though a date in the 1530s seems more likely. The wild turkey, the North American form of the bird, was so called from 1610s. By 1575, turkey was becoming the usual main course at an English Christmas. Meaning "inferior show, failure," is 1927 in show business slang, probably from the bird's reputation for stupidity. Meaning "stupid, ineffectual person" is recorded from 1951. Turkey shoot "something easy" is World War II-era, in reference to marksmanship contests where turkeys were tied behind a log with their heads showing as targets. To talk turkey (1824) supposedly comes from an old tale of a Yankee attempting to swindle an Indian in dividing up a turkey and a buzzard as food.

- turmeric (n.)
- pungent powder made from the root of an East Indian plant, 1530s, altered from Middle English turmeryte (early 15c.), of uncertain origin, perhaps from Middle French terremérite "saffron," from Medieval Latin terra merita, literally "worthy earth," though the reason why it would be called this is obscure. Klein suggests it might be a folk-etymology corruption of Arabic kurkum "curcuma, saffron."
- turmoil (n.)
- 1520s, of uncertain origin, perhaps an alteration of Middle French tremouille "mill hopper," in reference to the hopper's constant motion to and fro, from Latin trimodia "vessel containing three modii," from modius, a Roman dry measure, related to modus "measure." Attested earlier in English as a verb (1510s), though this now is obsolete.

Transitive sense in English is from c. 1300. Related: Turned; turning.
