'haphazardly-modified' originates from the combination of 'haphazardly' and 'modified'. 'Haphazardly' comes from 'haphazard', which originates from the Middle English 'hap' meaning 'chance' and 'hazard' meaning 'risk'. 'Modified' comes from the Latin 'modificare', where 'modi-' meant 'measure' and 'facere' meant 'to make'.

'Haphazardly-modified' combines the adverb 'haphazardly' and the past participle 'modified', reflecting a modern English construction.

Initially, 'haphazardly' meant 'by chance', and 'modified' meant 'to make changes'. Together, they evolved to describe something altered without a clear plan.
