'haphazardly-performed' originates from the combination of 'haphazardly' and 'performed'. 'Haphazardly' comes from 'hap' meaning 'chance' and 'hazard' meaning 'risk', while 'performed' is derived from the Latin 'performare', meaning 'to complete'.

'Haphazardly' evolved from the Middle English 'hap' and 'hazard', while 'performed' came from the Old French 'parfournir'.

Initially, 'haphazardly' meant 'by chance', and 'performed' meant 'to complete'. Over time, 'haphazardly-performed' evolved to mean 'done in a careless or disorganized manner'.
