'unpersuaded' originates from the prefix 'un-' meaning 'not' and the verb 'persuade' from Latin 'persuadere', where 'per-' meant 'through' and 'suadere' meant 'to advise'.

'persuadere' transformed into the Old French word 'persuader', and eventually became the modern English word 'persuade'. The prefix 'un-' was added to form 'unpersuaded'.

Initially, 'persuade' meant 'to advise thoroughly', and 'unpersuaded' has retained the meaning of 'not being advised or convinced'.
