'amphigonia' originates from Greek, specifically the word 'amphigonía,' where 'amphi-' meant 'both' and 'gonía' meant 'generation or birth.'

'amphigonía' transformed into the Latin word 'amphigonia,' and eventually became the modern English word 'amphigonia.'

Initially, it meant 'both types of generation,' and this meaning has largely remained the same in modern usage.
