carbon 英文词源

carbon

carbon: [18] The notion underlying carbon is probably that of ‘burning’; it has been tentatively traced back to a base *kar- ‘fire’. The word’s immediate source was French carbone, coined in the 1780s on the basis of Latin carbō ‘coal, charcoal’ (supplementing an earlier borrowing charbon ‘coal, charcoal’). It is not certain whether char and charcoal are related to it.

carbon (n.)

non-metallic element, 1789, coined 1787 in French by Lavoisier as charbone, from Latin carbonem (nominative carbo) "a coal, glowing coal; charcoal," from PIE root *ker- (4) "heat, fire, to burn" (cognates: Latin cremare "to burn;" Sanskrit kudayati "singes;" Lithuanian kuriu "to heat," karštas "hot," krosnis "oven;" Old Church Slavonic kurjo "to smoke," krada "fireplace, hearth;" Russian ceren "brazier;" Old High German harsta "roasting;" Gothic hauri "coal;" Old Norse hyrr "fire;" Old English heorð "hearth").

Carbon 14, long-lived radioactive isotope used in dating organic deposits, is from 1936. Carbon dating (using carbon 14) is recorded from 1958. Carbon cycle is attested from 1912. Carbon footprint was in use by 2001. Carbon paper (soon to be obsolete) is from 1895.
