means A salt or ester of nitric acid containing the NO₃ group, widely used in fertilizers, food preservatives, and explosives.

from From nitric acid plus the chemical suffix '-ate,' which marks a salt of an acid. 'Nitric' traces back through Latin 'nitrum' to Greek 'nitron,' a word for natural soda or mineral salts — itself likely borrowed from an earlier Egyptian or Semitic source for the natron the Egyptians used in embalming. So the name carries an ancient memory of salt dug from desert lakebeds, long before chemists pinned it to a particular cluster of nitrogen and oxygen.
