'haphazardly-assessed' originates from the combination of 'haphazardly' and 'assessed'. 'Haphazardly' comes from 'haphazard', which originates from the Middle English word 'hap', meaning 'chance', and 'hazard', meaning 'risk'. 'Assessed' comes from the Latin word 'assessus', meaning 'to sit by' or 'to judge'.

'Haphazardly' evolved from the Middle English 'hap' and 'hazard', while 'assessed' evolved from the Latin 'assessus'. The combination of these words into 'haphazardly-assessed' is a modern English construct.

Initially, 'haphazard' meant 'chance or risk', and 'assess' meant 'to judge'. Over time, 'haphazardly-assessed' evolved to mean 'evaluated in a random or careless manner'.
