'haphazardly-sectioned' originates from the combination of 'haphazardly' and 'sectioned'. 'Haphazardly' comes from 'haphazard', which originates from the Middle English word 'hap', meaning 'chance', and 'hazard', meaning 'risk'. 'Sectioned' is derived from the Latin word 'sectio', meaning 'a cutting'.

'Haphazardly' evolved from the Middle English 'hap' and 'hazard', while 'sectioned' evolved from the Latin 'sectio'.

Initially, 'haphazardly' meant 'by chance', and 'sectioned' meant 'cut into parts'. Over time, 'haphazardly-sectioned' came to mean 'divided in a random manner'.
