Word Origin & History

ammonia 
1799, coined 1782 by Swedish chemist Torbern Bergman for gas obtained from sal ammoniac, salt deposits containing ammonium chloride found near temple of Jupiter Ammon (from Egyptian God Amun) in Libya, from Gk. ammoniakon "belonging to Ammon." The shrine was already ancient 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 Gk. Armeniakon "Armenian," since the substance also was found in Armenia. Also known as Spirit of Hartshorn and Volatile or Animal Alkali.
