'randomly-altered' originates from the combination of 'randomly' and 'altered'. 'Randomly' comes from 'random', which has roots in Old French 'randir', meaning 'to gallop', and 'altered' comes from Latin 'alterare', meaning 'to change'.

'Randomly' evolved from the Old French 'randir', and 'altered' from Latin 'alterare', eventually forming the modern English term 'randomly-altered'.

Initially, 'randomly' meant 'without definite aim', and 'altered' meant 'changed'. Together, they convey the idea of changes made without a specific plan.
