'hexagonal' originates from Greek, specifically the word 'hexagōnos,' where 'hex' meant 'six' and 'gōnia' meant 'angle.'

'hexagōnos' transformed into the Latin word 'hexagonalis,' and eventually became the modern English word 'hexagonal' through Middle English.

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