'untraveled' originates from the prefix 'un-' meaning 'not' and the word 'traveled', which comes from the Old French 'travailler', meaning 'to work or toil'.

'travailler' transformed into the Middle English word 'travailen', and eventually became the modern English word 'travel'.

Initially, 'travel' meant 'to toil or labor', but over time it evolved into its current meaning of 'to journey or move from place to place'.
