'haphazardly-arranged' originates from the combination of 'haphazard' and 'arranged', where 'haphazard' comes from the Middle English word 'hap', meaning 'chance', and 'hazard', meaning 'risk'.

'haphazard' changed from the Middle English word 'hap' and 'hazard', and eventually became the modern English word 'haphazard'.

Initially, 'haphazard' meant 'by chance or risk', but over time it evolved into its current meaning of 'random or disorganized'.
