'unaberrated' originates from English prefix 'un-' (Old English 'un-' meaning 'not') combined with 'aberrated', which ultimately derives from Latin 'aberratus', specifically from 'aberrare', where 'ab-' meant 'away' and 'errare' meant 'to wander'.

'unaberrated' is a modern English formation made by adding the negative prefix 'un-' to 'aberrated'. 'Aberrated' itself comes from Latin 'aberratus' (past participle of 'aberrare') that entered scholarly and scientific English usage via Medieval Latin and later borrowings.

Initially the Latin root conveyed 'to wander away' or 'be out of the way'; over time in English 'aberrate' came to mean 'to deviate from the norm', and 'unaberrated' now expresses the opposite: 'not deviating' or 'without abnormal deviation'.
