'unsupervised' originates from the prefix 'un-' meaning 'not' and the word 'supervised' from Latin 'supervidere', where 'super-' meant 'over' and 'videre' meant 'to see'.

'supervidere' transformed into the Old French word 'superviser', and eventually became the modern English word 'supervise', with 'unsupervised' forming as its negative.

Initially, 'supervise' meant 'to oversee', and 'unsupervised' has consistently meant 'not overseen'.
