It seems to have cognates in Old Frisian and Middle Dutch kolk "pothole," Old English -colc, in compounds, "pit, hollow," Swedish dialectal kälk "pith." Perhaps the notion is the "core" of the coal, or "what is left in the pit after a fire."

slang shortened form of cocaine (q.v.), by 1902, American English.

col-

assimilated form of com- "with, together" before stems beginning in -l-. In early Latin, com- was assimilated to these as con-, but col- later also was used. Latin words in coll- became col- in Old French and thus in early Middle English but were altered back to coll- with the revival of learning.

cola (n.)

1795, genus of small evergreen trees native to west Africa, introduced and nativized in New World tropics, from a Latinized form of a West African name of the tree (compare Temne kola, Mandingo kolo). The cola-nut contains much caffeine.

Meaning "carbonated soft drink" is 1919, short for Coca-Cola, Pepsi-Cola, and their many imitators. A 1900 publication ("Alcohol," by the Woman's Christian Temperance Union) lists the names of drinks found to contain caffeine and extract of coca leaf:

colander (n.)

"vessel perforated with little holes to allow liquid to run off," mid-14c., coloundour, probably altered (with unetymological -n-) from Medieval Latin colatorium "strainer" from Latin colatus, past participle of colare "to strain," from colum "sieve, strainer, wicker fishing net," which is of uncertain origin.

Cognate with French couloir, Spanish colador, Italian colatojo. The word in English had a wide range of spellings (cullender, coloner, cullyandre, etc.), reflecting uncertainty of the etymology. "The form of the Eng. word appears to be due to some perversion; but its exact history is obscure" [OED]. As a verb, "to pass through a colander," 1874; earlier "riddle with holes" (1862). Related: Colandered.

The meaning "not strong, affecting the senses only slightly" (in reference to scent or trails in hunting or tracking) is from 1590s; hence the extended sense in seeking-games, "distant from the object of search" (1864).

Cold front in weather is from 1921. Cold sweat is by 1630s. Cold-call (v.) in the sales pitch sense is recorded by 1964 (implied in cold-calling; the noun cold call is by 1953; cold-selling is from 1947).

To throw cold water on in the figurative sense of "discourage by unexpected reluctance or indifference" is from 1808.

Cold cream, a cosmetic, is by 1709, translating Latin ceratum refrigerans, a preparation of oil, wax and water said to have been invented by 2c. Greek physician Galen. The name refers to the ancient theory of disease, where imbalance of "hot" and "cold" humors were believed to cause illness. The illness could be treated by remedies of the opposite nature, which however might not be "hot" or "cold" in a literal sense.

Japanese has two words for "cold:" samui for coldness in the atmosphere or environment; tsumetai for things which are cold to touch, and also in the figurative sense, with reference to personalities, behaviors, etc.

Related: Cold-bloodedly; cold-bloodedness.

cold feet (n.)

1893, American English, in the figurative sense "fear or doubt that reverses an intention to do something;" the presumed Italian original (avegh minga frecc i pee) is a Lombard proverb meaning "to have no money," but some of the earliest English usages refer to gamblers, so a connection is possible.

cold shoulder (n.)

1816, in the figurative sense of "icy reception, studied neglect or indifference," first in Sir Walter Scott, probably originally a literal figure (see cold (adj.)), but commonly used with a punning reference to "cold shoulder of mutton," considered a poor man's dish and thus, perhaps, something one would set out for an unwanted guest with deliberate intention to convey displeasure.

Formerly the literal figure was felt as associated with the image of the figurative "stubborn shoulder" in Nehemiah ix.29 (translating Latin humerum recedentum dare in Vulgate).

Originally with to show, later to give. As a verb from 1845; related: cold-shouldered. Also compare cold roast, old slang for "something insignificant." Cold pig was a 19c. term for throwing cold water on a sleeping person to wake him or her.

"without preparation," 1910; narrower sense of "withdrawal from an addictive substance" (originally heroin) first recorded 1921. Cold turkey is a food that requires little preparation, so "to quit like cold turkey" is to do so suddenly and without preparation. Compare cold shoulder. To do something cold "without preparation" is attested from 1896.

cold war (n.)

"nonhostile belligerency," used in print October 1945 by George Orwell; popularized in U.S. c. 1947 by U.S. statesman Bernard Baruch (1870-1965). Hence hot war (1947).

cole (n.1)

"cabbage," a dialectal survival of Middle English col, from late Old English cawel, or perhaps from or influenced by cognate Old Norse kal. Both words are from Latin caulis "stem, stalk" (which in Vulgar Latin replaced brassica as the usual word for "cabbage"), from Proto-Italic *kauli- "stalk," from PIE root *(s)kehuli- "stem of a plant, stalk" (source also of Old Irish cual "faggot, bundle of sticks," Greek kaulos "stem, stalk, pole," Armenian c'awl "stalk, straw," Old Prussian kaulan, Lithuanian káulas "bone").

Latin caulis "cabbage" is the source also of Italian cavolo, Spanish col, Old French chol, French chou; it also was borrowed elsewhere in Germanic, for example Swedish kål, Danish kaal, German Kohl, Dutch kool.

cole (n.2)

"trickery deceit," an obsolete 16c. word "of unknown etymology, and even of uncertain existence" [OED], inferred from words in several texts dating to c. 1300, "some of which might possibly be explained otherwise." These include notably cole-pixy "mischievous fairy" (1540s), a southwestern England dialect word (later colt-pixie) and cole-prophet "pretended mystical fortune-teller."

coliform (adj.)
