Chrysler [Chrysler 词源字典]: U.S. automobile corporation, organized 1925 as Chrysler Corporation by Walter P. Chrysler (1875-1940) out of the old Maxwell Motor Co. (Maxwell produced a car named Chrysler in 1924). The name is a spelling variant of German Kreisler, perhaps related to kreisel "spinning top," but the sense connection is unclear.[Chrysler etymology, Chrysler origin, 英语词源]
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"]
relativity (n.): 1834, "fact or condition of being relative" (apparently coined by Coleridge, of God, in "Notes on Waterland's Vindication of Christ's Divinity"), from relative (adj.) + -ity. In scientific use, connected to the theory of Albert Einstein (1879-1955), published 1905 (special theory of relativity) and 1915 (general theory of relativity), but the word was used in roughly this sense by J.C. Maxwell in 1876.
petalody: "Transformation of parts of a flower, usually stamens or sepals, into petals or petal-like structures (as a teratological or evolutionary phenomenon)", Mid 19th cent.; earliest use found in Maxwell Tylden Masters (1833–1907), botanist and journal editor. From ancient Greek πεταλώδης leaf-like + -y, apparently after petalodic.
