hydrogen: [18] Greek húdōr ‘water’ (a distant relative of English water) has been a prolific source of English vocabulary. Amongst its contributions are hydrangea [18] (literally ‘water-vessel’, so named from the cuplike shape of its seedpods), hydrant [19], hydrate [18], hydraulic [17] (literally ‘of a water-pipe’), hydrofoil [20], and hydroponics [20] (literally ‘water-culture’). Hydrogen itself means literally ‘generating water’, and was coined in French as hydrogène in the late 1780s for hydrogen’s property of forming water when oxidized. It is first recorded in English in 1791. => water
hydrogen (n.)
1791, from French hydrogène, coined 1787 by G. de Morveau, Lavoisier, Berthollet, and Fourcroy from Greek hydr-, stem of hydor "water" (see water (n.1)) + French -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.
