oxygen: [18] Etymologically, oxygen means ‘a(chǎn)cid-former’. The word was coined in French in the late 1780s as oxygène, based on Greek oxús ‘sharp, acid’ (a descendant of the same Indo- European base, *ak- ‘be pointed’, as produced English acid, acute, etc) and the Greek suffixgenes, denoting ‘formation, creation’ (a descendant of the Indo-European base *gen- ‘produce’, which has given English a vast range of words, from gene to genocide). => acid, acute, eager, gene, general, generate
oxygen (n.)
gaseous chemical element, 1790, from French oxygène, coined in 1777 by French chemist Antoine-Laurent Lavoisier (1743-1794), from Greek oxys "sharp, acid" (see acrid) + French -gène "something that produces" (from Greek -genes "formation, creation;" see -gen).
Intended to mean "acidifying (principle)," it was a Greeking of French principe acidifiant. So called because oxygen was then considered essential in the formation of acids (it is now known not to be). The element was isolated by Priestley (1774), who, using the old model of chemistry, called it dephlogisticated air. The downfall of the phlogiston theory required a new name, which Lavoisier provided.
