tutor

tutor: [14] A tutor is etymologically someone who ‘looks after’ another – indeed, it was originally used for a ‘guardian’ or ‘protector’: ‘The king … behested himself to be a tutor and defender of him and of his’, Foundation of St Bartholomew’s church 1425. The word’s educational connotations are a secondary development. It comes via Anglo-Norman tutour from Latin tūtor, a derivative of tuērī ‘look after, protect’. From the same source comes English tuition [15], and also tutelage [17], which retains its original sense of ‘guardianship’.
=> tuition, tutelage
