 Usage: Cloister and convent are generic terms, and denote a place of seclusion from the world for persons who devote their lives to religious purposes. They differ is that the distinctive idea of cloister is that of seclusion from the world, that of convent, community of living. Both terms denote houses for recluses of either sex. A cloister or convent for monks is called a monastery; for nuns, a nunnery. An abbey is a convent or monastic institution governed by an abbot or an abbess; a priory is one governed by a prior or a prioress, and is usually affiliated to an abbey.
