Etymology

borrowed from New Latin, derivative based on Latin sal ammōniacus "rock salt," literally, "salt of Ammon," from ammōniacus "of Ammon," borrowed from Greek ammōniakós, derivative of Ámmōn, an Egyptian deity identified by the Greeks with Zeus, borrowed from Egyptian ỉmn; from its having been extracted near an oracle of Ammon near the Siwa oasis in Egypt

Note: The identification of sal ammoniac, not well described by ancient authors, as ammonium chloride was apparently part of medieval alchemical tradition.
