'amphibolous' originates from Greek, specifically the word 'amphibolos,' where 'amphi-' meant 'both' and 'ballein' meant 'to throw.'

'amphibolos' transformed into the Latin word 'amphibolus,' and eventually became the modern English word 'amphibolous.'

Initially, it meant 'to throw both ways,' but over time it evolved into its current meaning of 'having a double or ambiguous meaning.'
