crankshaft (n.)[crankshaft 词源字典]: 1803, from crank (v.) + shaft (n.). The basic form of the mechanism appears to date from Roman times.[crankshaft etymology, crankshaft origin, 英语词源]
cranky (adj.): "cross-tempered, irritable," 1807, from crank (n.) + -y (2). The evolution would be from earlier senses of crank, such as "a twist or fanciful turn of speech" (1590s); "inaccessible hole or crevice" (1560s). Grose's 1787 "Provincial Glossary" has "Cranky. Ailing sickly from the dutch crank, sick," and identifies it as a Northern word. Jamieson's Scottish dictionary (1825) has crank in a secondary sense of "hard, difficult," as in crank word, "a word hard to be understood;" crank job, "a work attended with difficulty, or requiring ingenuity in the execution." Related: Crankily; crankiness.
Ben. Dang it, don't you spare him--A cross grain'd cranky toad as ever crawl'd. (etc.) [Richard Cumberland, "Lovers Resolutions," Act I, 1813]
cranny (n.): mid-15c., possibly from a diminutive of Middle French cran "notch, fissure" (14c.), from crener "to notch, split," from Medieval Latin crenare, possibly from Latin cernere "to separate, sift" (see crisis). But OED casts doubt on this derivation.
crap (v.): "defecate," 1846, from one of a cluster of words generally applied to things cast off or discarded (such as "weeds growing among corn" (early 15c.), "residue from renderings" (late 15c.), underworld slang for "money" (18c.), and in Shropshire, "dregs of beer or ale"), all probably from Middle English crappe "grain that was trodden underfoot in a barn, chaff" (mid-15c.), from Middle French crape "siftings," from Old French crappe, from Medieval Latin crappa, crapinum "chaff." Related: Crapped; crapping.

Despite folk etymology insistence, not from Thomas Crapper (1837-1910) who was, however, a busy plumber and may have had some minor role in the development of modern toilets. The name Crapper is a northern form of Cropper (attested from 1221), an occupational surname, obviously, but the exact reference is unclear. Crap (v.) as a variant of crop (v.) was noted early 19c, as a peculiarity of speech in Scotland and the U.S. Southwest (Arkansas, etc.).
Draw out yere sword, thou vile South'ron!
Red wat wi' blude o' my kin!
That sword it crapped the bonniest flower
E'er lifted its head to the sun!

[Allan Cunningham (1784-1842), "The Young Maxwell"]

craps (n.): 1843, American English, unrelated to the term for excrement, instead it is from Louisiana French craps "the game of hazard," from an 18c. continental French corruption of English crabs, which was 18c. slang for "a throw of two or three" (the lowest throw), which perhaps is from crab (n.2), the sense in crab apple. The 1843 citation (in an anti-gambling publication, "An Exposure of the Arts and Miseries of Gambling") calls it "a game lately introduced into New Orleans."

crate (n.): "large box," 1680s, earlier "hurdle, grillwork" (late 14c.), from Latin cratis "wickerwork, lattice, kitchen-rack," or from Dutch krat "basket;" both perhaps from a common PIE root *kert- "to turn, entwine" (see hurdle (n.)).
