A convent is either a community of priests, religious brothers/sisters, or nuns, or the building used by the community, particularly in the Roman Catholic Church and in the Anglican Communion. The terms "convent" or "nunnery" almost invariably refers to a community of women in modern English usage (from 18th century), while "monastery", "priory" or "friary" is used for men; but in historical usage they are often interchangeable.
