'randomly-enforced' originates from the combination of 'randomly' and 'enforced'. 'Randomly' comes from 'random', which has roots in Old French 'randir', meaning 'to gallop', and 'enforced' comes from 'enforce', which originates from Old French 'enforcier', meaning 'to strengthen'.

'randomly' evolved from the Old French 'randir', and 'enforced' evolved from the Old French 'enforcier'. The combination of these words into 'randomly-enforced' is a modern English construct.

Initially, 'randomly' meant 'haphazardly' and 'enforced' meant 'to compel'. Together, they evolved to describe something applied in an unpredictable manner.
