'irrefutably-formed' originates from the combination of 'irrefutable' and 'formed', where 'irrefutable' comes from Latin 'irrefutabilis', meaning 'not able to be refuted', and 'formed' from Old English 'formian', meaning 'to shape or create'.

'irrefutabilis' transformed into the English word 'irrefutable', and 'formian' evolved into 'formed', eventually combining to create the modern term 'irrefutably-formed'.

Initially, 'irrefutable' meant 'not able to be refuted', and 'formed' meant 'shaped or created'. Together, they evolved to mean 'formed in a manner that cannot be refuted'.
