Servitor
In certain universities, a servitor was an undergraduate student who received free accommodation, and was exempted from paying fees for lectures. The term is still used at the University of Edinburgh, where it refers to the staff who are responsible for security, mail and reception and are also on duty at formal occasions, when their functions include carrying the mace and ushering.
At Oxford, servitors were originally expected to act as servants to the fellows of their college. By 1852 this requirement had largely fallen into disuse, and the term had been replaced at most colleges. The last recorded use of the term in Oxford was in 1867.
