'incontrovertibly-formed' originates from the combination of 'incontrovertible' and 'formed'. 'Incontrovertible' comes from Latin, specifically the word 'incontrovertibilis', where 'in-' meant 'not' and 'controvertibilis' meant 'able to be disputed'.

'incontrovertibilis' transformed into the English word 'incontrovertible', and eventually combined with 'formed' to create the modern English word 'incontrovertibly-formed'.

Initially, 'incontrovertible' meant 'not able to be disputed', and this meaning has largely remained the same in modern usage when combined with 'formed'.
