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

'Haphazard' evolved from the Middle English 'hap' and 'hazard', and 'organized' from the Latin 'organizare', meaning 'to arrange'.

Initially, 'haphazard' meant 'by chance', but over time it evolved to imply a lack of order or planning.
