'tutor' originates from Latin, specifically the word 'tutor', where the root 'tueri' meant 'to guard' or 'watch over'.

'tutor' in English developed via Medieval/Latin usage (and via Anglo-Norman/French influence such as Old French/Norman forms) from the Latin 'tutor' and came into Middle English as 'tutor', eventually becoming the modern English 'tutor'.

Initially, it meant 'a watcher or guardian' (someone who protects or looks after another); over time the sense shifted toward 'one who instructs or gives guidance', leading to the current primary meaning 'teacher/coach'.
