'feasibly-altered' originates from the combination of 'feasible' and 'altered'. 'Feasible' comes from Old French 'faisable', meaning 'that may be done', and 'altered' from Latin 'alterare', meaning 'to change'.

'feasible' evolved from Old French 'faisable' and 'altered' from Latin 'alterare', eventually combining in modern English to form 'feasibly-altered'.

Initially, 'feasible' meant 'that may be done', and 'altered' meant 'to change'. Together, they evolved to mean 'capable of being changed in a practical manner'.
