ONLINE ETYMOLOGY DICTIONARY

nitric (adj.)

1794, originally in reference to acid obtained initially from distillation of saltpeter; see nitre + -ic. Perhaps immediately from Fr. nitrique. Known as aqua fortis, later acid spirit of nitre, then nitric acid. (1787) under the system ordered by Lavoisier.

nitre (n.)

c.1400, "native sodium carbonate," from O.Fr. nitre (13c.), from L. nitrum, from Gk. nitron, which is possibly of Eastern origin (cf. Heb. nether "carbonate of soda;" Egyptian ntr). Originally a word for native soda, but also associated from Middle Ages with saltpeter (potassium nitrate) for obscure reasons; this became the predominant sense by late 16c.
