'haphazardly-recorded' originates in modern English as a compound of the adverb 'haphazardly' and the past participle 'recorded'. 'haphazardly' traces to 'haphazard' (from 'hap' meaning 'chance, luck' + 'hazard' meaning 'chance, risk'), while 'recorded' comes from the verb 'record', ultimately from Latin 'recordari', where 're-' meant 'again' and 'cor' (later 'cord-') meant 'heart, mind'.

'haphazard' developed in Early Modern English from 'hap' + 'hazard'; the adverb 'haphazardly' formed with the suffix '-ly'. 'Record' entered English via Old French 'record(er)' and Middle English, from Latin 'recordari'; its past participle 'recorded' began to be used adjectivally. These elements later combined in modern usage to form the attributive compound 'haphazardly-recorded'.

Originally, the elements meant 'by chance' and 'set down/remember again'; together they came to describe audio or written material captured in an unsystematic, careless manner.
