'haphazardly-chosen' originates from the combination of 'haphazardly' and 'chosen'. 'Haphazardly' comes from 'haphazard', which originates from the Middle English word 'hap', meaning 'chance', and 'hazard', meaning 'risk'. 'Chosen' is the past participle of 'choose', which comes from the Old English 'cēosan'.

'Haphazardly' evolved from 'hap' and 'hazard', while 'chosen' evolved from 'cēosan'. The combination of these words formed the modern term 'haphazardly-chosen'.

Initially, 'haphazard' meant 'chance or risk', and 'chosen' meant 'selected'. Together, they evolved to mean 'selected without a plan'.
