carbide (n.)

non-metallic element occurring naturally as diamond, graphite, or charcoal, 1789, coined 1787 in French by Lavoisier as charbone, from Latin carbonem (nominative carbo) "a coal, glowing coal; charcoal," from PIE root *ker- (3) "heat, fire."

Carbon 14, the 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 "paper faced with carbon, used between two sheets for reproduction on the lower of what is drawn or written on the upper" is from 1855, earlier it was carbonic paper (1850).

word-forming element used in chemistry to coin names for simple compounds of one element with another element or radical; originally abstracted from oxide, which was the first so classified, in which the -ide is from acide "acid."

The suffix is really -dus (-do-), the -i- repr. the orig. or supplied stem-vowel ; it occurs without the vowel in absurdus, absurd, blandus, bland, crudus, raw (crude), etc. [Century Dictionary]

also carburator, carburettor, device to enhance a gas flame by adding volatile hydrocarbons, 1866, from carburet "compound of carbon and another substance" (1795, now displaced by carbide), also used as a verb, "to combine with carbon" (1802); from carb-, combining form of carbon, + -uret, an archaic suffix from Modern Latin -uretum, used in English to parallel French words in -ure. Motor vehicle sense "apparatus for injecting fuel in fine particles into air to prepare it for the cylinder" is from 1896.
