'unaudited' originates from English: it combines the prefix 'un-' (Old English 'un-', meaning 'not') with the verb 'audit', which ultimately comes from Latin 'audire', where 'audire' meant 'to hear'.

'audit' developed from Latin 'audire' (past participle 'auditus') into Anglo-Latin/Old French and then Middle English (e.g. 'auditen'/'audit'); the modern adjective 'unaudited' was formed in English by adding the negative prefix 'un-' to 'audited'.

Initially related to 'hearing' in Latin, 'audit' shifted to mean an official examination (especially of accounts); consequently, 'unaudited' came to mean 'not examined' in that sense.
