ETYMOLOGY DICTIONARY:
- hydrocarbon (n.)
- "compound of hydrogen and carbon," 1826, formed in English from hydrogen + carbon.
- hydrogen (n.)
- 1791, from Fr. hydrogène, coined 1787 by G. de Morveau, Lavoisier, Berthollet, and Fourcroy from Gk. hydr-, stem of hydros "water" (see water (n.1)) + Fr. -gène "producing" (see -gen). So called because it forms water when exposed to oxygen. Nativized in Russian as vodorod; in German, it is wasserstoff, "water-stuff." An earlier name for it in English was Cavendish's inflammable air (1767). Hydrogen bomb first recorded 1947; shortened form H-bomb is from 1950.
- carbon (n.)
- non-metallic element, 1789,
coined 1787 in French by Lavoisier as charbone, from L. carbo
(gen. carbonis) "glowing coal, charcoal," from PIE root
*ker- "heat, fire, to burn" (cf. L. cremare "to
burn;" Skt. krsna "black, burnt," kudayati
"singes;" Lith. kuriu "to heat," karštas
"hot," krosnis "oven;" O.C.S. kurjo "to
smoke," krada "fireplace, hearth;" Rus. ceren
"brazier;" O.H.G. harsta "roasting;" Goth.
hauri "coal;" O.N. hyrr "fire;" O.E. 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.
