'amianthiform' originates from Greek, specifically the word 'amiantos,' where 'a-' meant 'not' and 'miantos' meant 'defiled.'

'amiantos' transformed into the Latin word 'amianthus,' and eventually became the modern English word 'amianthiform.'

Initially, it meant 'undefiled or pure,' but over time it evolved into its current meaning of 'resembling amianthus.'
