"outer part of the perianth of a flower," 1680s, from Latin calyx, from Greek kalyx "seed pod, husk, outer covering" (of a fruit, flower bud, etc.), from stem of kalyptein "to cover, conceal," from PIE root *kel- (1) "to cover, conceal, save." The Latin plural is calyces. Some sources connect the word rather with Greek kylix "drinking cup" (see chalice).
type of Italian stuffed turnover, a specialty of Naples, Italian, literally "trouser leg," so called for the resemblance.
1777, "a projecting part of a rotating machinery used to impart motion to another part," from Dutch cam "cog of a wheel," originally "comb," from Proto-Germanic *kambaz "comb," from PIE root *gembh- "tooth, nail." It is thus a cognate of English comb (n.). This might have combined with English camber "having a slight arch;" or the whole thing could be from camber.
It converts regular rotary motion into irregular, fast-and-slow rotary or reciprocal motion. "The original method was by cogs or teeth fixed or cut at certain points in the circumference or disc of a wheel ..." [OED]. Cam-shaft attested from 1850.
"companionship, good-fellowship," 1840, from French camaraderie, from camarade "comrade" (see comrade).

1670s in botany, "layer of tissue between the wood and the bark," from Late Latin cambium "exchange," from Latin cambiare "change" (see change (v.)).
Southeast Asian nation, the name is said to be from Kambu, legendary ancestor of the people. Related: Cambodian.
1650s, "from or of Wales or the Welsh," from Cambria, variant of Cumbria, Latinized derivation of Cymry, the name of the Welsh for themselves, from Old Celtic Combroges "compatriots." The geological sense (in reference to Paleozoic rocks first studied in Wales and Cumberland) is from 1836.
type of thin, fine linen, late 14c., from Dutch Kamerijk or Flemish Kameryk, Germanic forms of French Cambrai, name of the city in northern France where the cloth was said to have been first manufactured. The modern form of the English word has elements from both versions of the name. The place-name is from Latin Camaracum, according to Room from the personal name Camarus, "itself apparently from Latin cammarus 'a crawfish, prawn' .... It is not known who this was."
