'untalented' originates from the prefix 'un-' meaning 'not' and the word 'talented', which comes from the Latin word 'talentum', meaning 'inclination or natural ability'.

'talentum' transformed into the Old English word 'talent', and eventually became the modern English word 'talented'. The prefix 'un-' was added to form 'untalented'.

Initially, 'talentum' meant 'inclination or natural ability', and 'untalented' has retained the meaning of lacking such ability.
