A convent is either a community of priests, religious brothers or religious sisters (nuns); or the building used by the community, particularly in the Roman Catholic Church and in the Anglican Communion. In English usage since about the 19th century the term "convent" almost invariably refers to a community of women, while "monastery" and "friary" are used for men; other terms used are abbey, priory etc. In historical usage they are often interchangeable, with "convent" especially likely to be used for a friary.
