'amphibious' originates from Greek, specifically the word 'amphibios,' where 'amphi-' meant 'both' and 'bios' meant 'life.'

'amphibios' transformed into the Latin word 'amphibius,' and eventually became the modern English word 'amphibious' through Middle English.

Initially, it meant 'living both on land and in water,' but over time it evolved into its current meaning of 'capable of operating on both land and water.'
