'haphazardly-positioned' originates from the combination of 'haphazardly' and 'positioned'. 'Haphazardly' comes from 'haphazard', which originates from the Old Norse word 'happ', meaning 'chance', and 'hazard', from the Arabic 'al-zahr', meaning 'the dice'. 'Positioned' comes from the Latin 'positio', meaning 'placement'.

'Haphazardly' evolved from the Middle English 'hap hasard', meaning 'chance hazard', and 'positioned' from the Latin 'positio'.

Initially, 'haphazardly' meant 'by chance', and 'positioned' meant 'placed'. Together, they evolved to describe something placed without order.
