ammonia: ammonia: [18] Ammonia gets its name ultimately from Amon, or Amen, the Egyptian god of life and reproduction. Near the temple of Amon in Libya were found deposits of ammonium chloride, which was hence named sal ammoniac – ‘salt of Amon’. The gas nitrogen hydride is derived from sal ammoniac, and in 1782 the Swedish chemist Torbern Bergman coined the term ammonia for it.
ammonia (n.): 1799, Modern Latin, coined 1782 by Swedish chemist Torbern Bergman (1735-1784) for gas obtained from sal ammoniac, salt deposits containing ammonium chloride found near temple of Jupiter Ammon (from Egyptian God Amun) in Libya, from Greek ammoniakos "belonging to Ammon." The shrine was ancient already in Augustus' day, and the salts were prepared "from the sands where the camels waited while their masters prayed for good omens" [Shipley].

There also was a gum form of sal ammoniac, from a wild plant that grew near the shrine, and across North Africa and Asia. A less likely theory traces the name to Greek Armeniakon "Armenian," because the substance also was found in Armenia. Also known as spirit of hartshorn and volatile or animal alkali.
