'ammonion' originates from the Latin word 'ammoniacum', which referred to a type of salt found near the temple of Jupiter Ammon in Libya.

'ammoniacum' transformed into the French word 'ammoniaque', and eventually became the modern English word 'ammonion'.

Initially, it referred to a type of salt, but over time it evolved into its current meaning of a rare mineral composed of ammonium chloride.
