The unetymological -b- appeared mid-15c., in part by analogy with words like dumb. Slang meaning "lousy person" is 1918, from crumb, U.S. slang for "body-louse" (1863), which were so called from resemblance.ETD crumb (n.).3

sort of tea-cake, 1690s, perhaps from crompid cake "wafer," literally "curled-up cake" (1382; Wyclif's rendering of Hebrew raqiq in Exodus xxix.23), from crompid, past participle of crumpen "curl up" (see crumple (v.)).

1892, from crunch (n.) + -y (2). Student slang sense of "annoyingly intense about health or environmental issues" is by 1990, short for crunchy granola (considered a natural and wholesome food) used as an adjective.

Century Dictionary writes, "Akin to crook, with which in the Romance languages its derivatives are mingled" (Italian gruccia "crutch," crocco "hook" are Germanic loan-words).ETD crutch (n.).4
1814, "a cross," from Latin crux "cross," a word of uncertain origin. Sometimes said to be cognate with Irish cruach "heap, hill," Gaulish *krouka "summit," Old Norse hryggr "backbone," Old English hrycg "back." But de Vaan is suspicious:ETD crux (n.).2
The figurative use for "a central difficulty" (1718) is older in English than the literal sense; perhaps it is from Latin crux interpretum "a point in a text that is impossible to interpret," the literal meaning of which is something like "crossroads of interpreters." But Century Dictionary ascribes it to "the cross as an instrument of torture; hence anything that puzzles or vexes in a high degree ...." Extended sense of "central point" is attested by 1888.ETD crux (n.).3
late 14c., "roaring, shouting;" 1590s, "wailing, weeping," present-participle adjective from cry (v.). Sense of "demanding attention or remedy" is from c. 1600.

Perhaps it is a variant of quirritare "to squeal like a pig," from *quis, echoic of squealing. Ancient folk etymology explained it as "to call for the help of the Quirites," the Roman constabulary.ETD cry (v.).3
The meaning was extended 13c. to the sense "shed tears" that had formerly been in weep, which it largely replaced by 16c., via the notion of "utter a loud, vehement, inarticulate sound." To cry (one's) eyes out "weep inordinately" is by 1704.ETD cry (v.).4
Most languages, in common with English, use the general word for "cry out, shout, wail" to also mean "weep, shed tears to express pain or grief." Romance and Slavic, however, use words for this whose ultimate meaning is "beat (the breast)," compare French pleurer, Spanish llorar, both from Latin plorare "cry aloud," but probably originally plodere "beat, clap the hands." Also Italian piangere (cognate with French plaindre "lament, pity") from Latin plangere, originally "beat," but especially of the breast, as a sign of grief. Related: Cried; crying.ETD cry (v.).5

The notion in far cry "a great distance, a long way" seems to be "calling distance;" compare out of cry "out of calling distance" (mid-14c.); within cry of "within calling distance" (1630s). Far cry itself seems to have been a Scottish phrase popularized by Scott ("Rob Roy," 1817), which notes that "The expression of a 'far cry to Lochow,' was proverbial."ETD cry (n.).3
also cry-baby, derisive word for one who cries too easily or too much, 1851, American English, from cry + baby (n.).ETD crybaby (n.).2

Comparison has been made to Old Church Slavonic kryjo, kryti "to hide," Lithuanian kráuti "to pile up." Beekes writes that krypto "is formally and semantically reminiscent of [kalypto]; the verbs may have influenced each other." For this, see calypto-. But he adds, "However, since there is no good IE etymology, the word could be Pre-Greek." Meaning "underground burial vault or chapel in a church" is attested by 1789.ETD crypt (n.).2

In 19c. often of secret religious faith; from 1870s in scientific words; since c. 1945 typically of hidden political loyalties. Crypto-fascist is attested from 1937; crypto-communist from 1946. Hence, as an abstracted noun, crypto "person who conceals a political adherence" (1946).ETD crypto-.3
"a message or writing in secret characters or code," 1849, from crypto- "secret, hidden" + gram "word, letter."

The mathematical also was in the ancient Greek word: the Greeks threw with three dice; the highest possible roll was three sixes. The word was attested in English from late 14c. in Latin form.

ancient unit of measure (usually from 18 to 22 inches) based on the forearm from elbow to fingertip, early 14c., from Latin cubitum, cubitus "the elbow, the forearm," generally regarded as a derivative of PIE *keu(b)- "to bend," but de Vaan finds this dubious based on the sense of the proposed cognates and the sound changes involved. Also compare cubicle.ETD cubit (n.).2
Such a measure, known by a word meaning "forearm" or the like, was known to many peoples (compare Greek pekhys, Hebrew ammah, English ell).ETD cubit (n.).3
The word also was used in English in the "forearm, part of the arm from the elbow downward" sense (early 15c.); hence cubital "as long as a cubit" (mid-15c.), also "pertaining to the forearm" (1610s).ETD cubit (n.).4
"cube-like, resembling a cube in form," 1829, a modern coinage; see cube (n.) + -oid. As a noun, short for cuboid bone, by 1839. Related: Cuboidal.ETD cuboid (adj.).2
"to void excrement," mid-15c., cukken, from Old Norse kuka "feces," from PIE root *kakka- "to defecate." From 1610s as "to put in the cucking-stool." Related: Cucked; cucking.ETD cuck (v.1).2
"make (someone) a cuckold," 2007, verb abstracted from cuckold. According to Partridge Dictionary of Slang, the word originated in fetish terminology, and by 2000 it is attested as a genre tag for internet erotica.ETD cuck (v.2).2
early 13c., from verbal noun from cuck "to void excrement," from Old Norse kuka "feces," from PIE root *kakka- "to defecate." So called because they sometimes resembled the old close stool of the pre-plumbing days, a portable indoor toilet that looked like a chair with a box under the seat. Old folk etymology made the first element a corruption of cotquean. For second element, see stool. Also known as trebucket and castigatory, it was used on fraudulent tradesmen, in addition to disorderly women, either for public exposure to ridicule or for ducking.ETD cucking-stool (n.).2
derisive name for a man whose wife is false to him, "husband of an adulteress," early 13c., kukewald, cokewold, from Old French cucuault, from cocu (see cuckoo) + pejorative suffix -ault, of Germanic origin. So called from the female bird's alleged habit of changing mates, or her authentic habit of leaving eggs in another bird's nest.ETD cuckold (n.).2
In Modern French the identity is more obvious: Coucou for the bird and cocu for the betrayed husband. German Hahnrei (13c.), from Low German, is of obscure origin. The second element seems to be connected to words for "ardent," and suggests perhaps "sexually aggressive hen," with transferal to humans, but Kluge suggests rather a connection to words for "capon" and "castrated." The female equivalent, cuckquean, is attested by 1560s.ETD cuckold (n.).3
of a wife or her paramour, "to dishonor (a husband) by adultery," 1580s, from cuckold (n.). Related: Cuckolded; cuckolding.ETD cuckold (v.).2

European bird noted for its love-note cry and notorious for parasitism, c. 1300, cokkou (late 12c. as a surname), from Old French cocu "cuckoo," also "cuckold," echoic of the male bird's mating cry (compare Greek kokkyx, Latin cuculus, Middle Irish cuach, Sanskrit kokilas).ETD cuckoo (n.).2
Slang adjectival sense of "crazy" is American English, 1918, but noun meaning "stupid person" is recorded by 1580s, perhaps from the bird's unvarying, oft-repeated call. The Old English name was ʒeac, cognate with Old Norse gaukr, source of Scottish and northern English gowk, which also has insulting senses. The Germanic words presumably originally were echoic, too, but had drifted in form. Cuckoo-clock is from 1789.ETD cuckoo (n.).3
"common running garden plant," cultivated from earliest times in many Old World countries, also the long, fleshy fruit of the plant, late 14c., cucomer, from Old French cocombre (13c., Modern French concombre), from Latin cucumerem (nominative cucumis), perhaps from a pre-Italic Mediterranean language. The Latin word also is the source of Italian cocomero, Spanish cohombro, Portuguese cogombro. Replaced Old English eorþæppla (plural), literally "earth-apples."ETD cucumber (n.).2
Cowcumber was the common form of the word in 17c.-18c., in good literary use and representing the modern evolution of the Middle English form. Cucumber is an attempted reversion to Latin. In 1790s the pronunciation "cowcumber" was standard except in western England dialects and "coocumber" was considered pedantic, but 30 years later, with the spread of literacy and education "cowcumber" was limited to the ignorant and old-fashioned.ETD cucumber (n.).3
It was planted as a garden vegetable by 1609 by Jamestown colonists. Short form cuke is attested by 1977. Phrase cool as a cucumber (c. 1732) embodies ancient folk knowledge confirmed by science in 1970: inside of a field cucumber on a warm day is 20 degrees cooler than the air temperature. The sea-cucumber (1841) is so called for the shape of some species.ETD cucumber (n.).4
"portion of food voluntarily forced into the mouth by the stomach of a ruminating animal," Old English cudu "cud," also "gum, resin, mastic," earlier cwudu, from Proto-Germanic *kweduz "resin" (source also of Old Norse kvaða "resin," Old High German quiti "glue," German Kitt "putty").ETD cud (n.).2
"hug, embrace so as to keep warm; lie close or snug," 1520s (implied in cudlyng), of uncertain origin. OED calls it "A dialectal or nursery word." Perhaps a variant or frequentative form of obsolete cull, coll "to embrace" (see collar (n.)); or perhaps from Middle English *couthelen, from couth "known," hence "comfortable with." It has a spotty early history and seems to have been a nursery word at first. Related: Cuddled; cuddling. As a noun, "a hug, an embrace," by 1825.ETD cuddle (v.).2
"cuddlesome, given to or inviting cuddles," 1863, from cuddle + -y (2).ETD cuddly (adj.).2

"words spoken at the end of a speech in a play that are the signal for an answering speech," 1550s, of uncertain origin. By one theory it is a spelling out of Q, the letter, which was used 16c., 17c. in stage plays to indicate actors' entrances and was explained at the time as an abbreviation of Latin quando "when" (from PIE root *kwo-, stem of relative and interrogative pronouns) or a similar Latin adverb. Shakespeare's printed texts have it as both Q and cue. Cue as a name for "the letter Q" is attested from 1755.ETD cue (n.1).2

Meaning "straight, tapering rod with a small soft pad, used in billiards," is by 1749. Hence cue-ball, the ball struck by the cue, recorded by 1881.ETD cue (n.2).2
1928, "provide or furnish with a (theatrical or musical) cue," from cue (n.1). Meaning "tie in a cue or tail" is from 1772, from cue (n.2). For "to stand in line" see the alternative spelling queue. Related: Cued, cueing.ETD cue (v.).2
"bottom of a sleeve," mid-14c., cuffe "hand covering, mitten, glove," perhaps from Medieval Latin cuffia, cuphia "head covering," which is of uncertain origin, perhaps ultimately from Greek.ETD cuff (n.).2
Sense of "band around the sleeve" is first attested 1520s; sense of "turned-up hem of trousers" is by 1896. Meaning "a fetter for the wrist" is from 1660s. Adverbial phrase off the cuff "extemporaneously" is attested by 1938, American English colloquial, suggesting an actor or speaker reading from notes jotted on his shirt sleeves rather than reciting learned lines. Cuff-links (also cufflinks) is from 1887.ETD cuff (n.).3

(from PIE root *kwo-, stem of relative and interrogative pronouns) + bono "good" (see bene-).ETD cui bono.2
