Praepostor

Praepostor (sometimes spelt Praepositor) is now used chiefly at English independent schools, such as Aldenham, Brentwood, Clifton, Eton, Giggleswick, Harrow and Rugby and Shrewsbury as well as at other schools such as the former Derby School which began as grammar schools for the teaching of Latin grammar. It is the equivalent of prefect. The word originally referred to a monastic prior and is late Latin of the Middle Ages, derived from classical Latin praepositus, "placed before".
