crescendo (n.): 1776 as a musical term, from Italian crescendo "increasing," from Latin crescendo, ablative of gerund of crescere "to increase" (see crescent). Figurative use is from 1785. As a verb, from 1900.
crescent (n.): late 14c., "crescent-shaped ornament," from Anglo-French cressaunt, from Old French creissant "crescent of the moon" (12c., Modern French croissant), from Latin crescentum (nominative crescens), present participle of crescere "come forth, spring up, grow, thrive, swell, increase in numbers or strength," from PIE root *ker- (3) "to grow" (source also of Latin Ceres, goddess of agriculture, creare "to bring forth, create, produce;" Greek kouros "boy," kore "girl;" Armenian serem "bring forth," serim "be born").

Applied in Latin to the waxing moon, luna crescens, but subsequently in Latin mistaken to refer to the shape, not the stage. The original Latin sense is preserved in crescendo. A badge or emblem of the Turkish sultans (probably chosen for its suggestion of "increase"); figurative sense of "Muslim political power" is from 1580s, but modern writers often falsely associate it with the Saracens of the Crusades or the Moors of Spain. Horns of the waxing moon are on the viewer's left side; those of the waning moon are on his right.
cress (n.): Old English cresse, originally cærse, from Proto-Germanic *krasjon- (source also of Middle Low German kerse, karse; Middle Dutch kersse; Old High German kresso, German Kresse), from PIE root *gras- "to devour" (see gastric). It underwent a metathesis similar to that of grass. French cresson, Italian crescione are Germanic loan-words.
crest (n.): early 14c., from Old French creste "tuft, comb" (Modern French crête), from Latin crista "tuft, plume," perhaps related to word for "hair" (such as crinis), but it also was used for crest of a cock or a helmet. Replaced Old English hris.
crest (v.): late 14c., "provide with a crest," from Old French crester, from creste (see crest (n.)). Meaning "to come over the top of" is from 1832. Related: Crested; cresting.
crestfallen (adj.): 1580s, past participle adjective, but the verb crestfall is recorded only from 1610s, in reference to diseased horses, and is rare. It's possible that the image behind this use of the word is not cocks, as often is asserted, but horses.
cretaceous (adj.): 1670s, "chalky," from Latin cretaceus "chalk-like," from creta "chalk." As a geological period (with a capital C-), it was first used 1832. The extensive chalk beds of southeastern England were laid down during the Cretaceous.
Cretan (n.): Old English Cretense (plural), from Latin Cretanus (singular); see Crete. They were proverbial in ancient times as liars; compare Greek kretismos "lying," literally "Cretan behavior."
Crete: traditionally said to be from Krus, name of a mythological ancestor, but probably an ethnic name of some sort.
cretin (n.): 1779, from French crétin (18c.), from Alpine dialect crestin, "a dwarfed and deformed idiot" of a type formerly found in families in the Alpine lands, a condition caused by a congenital deficiency of thyroid hormones, from Vulgar Latin *christianus "a Christian," a generic term for "anyone," but often with a sense of "poor fellow."

cretonne (n.): 1870, from French cretonne (1723), supposedly from Creton, village in Normandy where it originally was made.
crevasse (n.): 1823, of glaciers; 1814, of riverbanks (in that case from Louisiana French), from French crevasse, from Old French crevace "crevice" (see crevice). Essentially the same word as crevice, but re-adopted in senses for which the meaning that had taken hold in crevice was felt to be too small.
crevice (n.): mid-14c., from Old French crevace (12c., Modern French crevasse) "gap, rift, crack" (also, vulgarly, "the female pudenda"), from Vulgar Latin *crepacia, from Latin crepare "to crack, creak" (see raven); meaning shifted from the sound of breaking to the resulting fissure.
crew (n.): mid-15c., "group of soldiers," from Middle French crue (Old French creue) "an increase, recruit, military reinforcement," from fem. past participle of creistre "grow," from Latin crescere "arise, grow" (see crescent). Meaning "people acting or working together" is first attested 1560s. "Gang of men on a warship" is from 1690s. Crew-cut first attested 1938, so called because the style originally was adopted by boat crews at Harvard and Yale.

crib (n.): Old English cribbe "manger, fodder bin in cowsheds and fields," from a West Germanic root (source also of Old Saxon kribbia "manger;" Old Frisian and Middle Dutch kribbe; Old High German krippa, German Krippe "crib, manger") probably related to German krebe "basket." Meaning "child's bed with barred sides" is 1640s; probably from frequent use in reference to the manger where infant Jesus was laid.

But Klein (citing Brugmann) rejects this and suggests *cri-men, which originally would have been "cry of distress" (Tucker also suggests a root in "cry" words and refers to English plaint, plaintiff, etc.). Meaning "offense punishable by law" is from late 14c. The Latin word is glossed in Old English by facen, also "deceit, fraud, treachery." Crime wave first attested 1893, American English.

Crip (n.): member of a major U.S. street gang, founded in South Central Los Angeles 1971, the name supposedly originally was cribs, partly a reference to the youth of most of the original members, and when they began carrying "pimp canes" it was altered to Crip, which has been attested in U.S. slang as a shortening of cripple (n.) since 1918.
cripple (n.): Old English crypel, related to cryppan "to crook, bend," from Proto-Germanic *krupilaz (source also of Old Frisian kreppel, Middle Dutch cropel, German krüppel, Old Norse kryppill). Possibly also related to Old English creopan "to creep" (creopere, literally "creeper," was another Old English word for "crippled person").
