'haphazardly-collected' originates from the combination of 'haphazardly' and 'collected'. 'Haphazardly' comes from 'haphazard', which originates from the Middle English word 'hap', meaning 'chance', and 'hazard', meaning 'risk'. 'Collected' is derived from the Latin word 'collectus', meaning 'gathered'.

'Haphazardly' evolved from the Middle English 'hap' and 'hazard', while 'collected' transformed from the Latin 'collectus' to the modern English 'collected'.

Initially, 'haphazardly' meant 'by chance or risk', and 'collected' meant 'gathered'. Together, they evolved to describe something gathered in a disorganized manner.
