The English word nitrogen (1794) entered the language from the French nitrogène, coined in 1790 by French chemist Jean Antoine Chaptal, from “nitre” + Fr. gène ”producing”
Other languages refer to nitrogen has ‘azote,’ from the greek word meaning lifeless, because of the inertness of diatomic nitrogen (Lavoisier himself named it this). Nitrogen is to this day still used to replace oxygen when a less reactive gas environment is needed.
The Dutch and German words for the element are stikstof and stickstoff, respectively. ‘Stik’ means to suffocate, which is what happened to any creatures the scientists put under pure nitrogen conditions; and ‘stof’ just means a substance.
