'amblygonite' originates from Greek, specifically the word 'amblygōnios,' where 'amblys' meant 'blunt' and 'gōnia' meant 'angle.'

'amblygōnios' transformed into the German word 'Amblygonit,' and eventually became the modern English word 'amblygonite.'

Initially, it meant 'blunt angle,' referring to the crystal's shape, and this meaning has largely remained the same in modern usage.
