'amblygonal' originates from Greek, specifically the word 'amblygōnia,' where 'amblys' meant 'dull' or 'blunt' and 'gōnia' meant 'angle.'

'amblygōnia' transformed into the English word 'amblygonal' through Latin influence.

Initially, it meant 'having dull or blunt angles,' and this meaning has largely remained the same in modern usage.
