'amphiboliferous' 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 'amphibole,' which is part of 'amphiboliferous.'

Initially, it meant 'ambiguous or doubtful,' but over time it evolved into its current meaning of 'containing amphibole minerals.'
