Word Origin & History
carbon
1789, coined 1780s in Fr. by Lavoisier as charbone, from L. carbo (gen. carbonis) "glowing coal, charcoal," from PIE base *ker- "heat, fire, to burn" (cf. L. cremare "to burn;" Skt. krsna "black, burnt," kudayati "singes;" Lith. kuriu "to heat," kartas "hot," krosnis "oven;" O.C.S. kurjo "to smoke,"
EXPAND 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.
