Minster is an honorific title given to particular churches in England, most famously York Minster in York, Westminster in London and Southwell Minster in Southwell. The term minster is first found in royal foundation charters of the 7th century. Although it corresponds to the Latin monasterium or monastery, it then designated any settlement of clergy living a communal life and endowed by charter with the obligation of maintaining the daily office of prayer. Widespread in 10th-century Anglo-Saxon England, minsters declined in importance with the systematic introduction of parishes and parish churches from the 11th century onwards. It continued as a title of dignity in later medieval England, for instances where a cathedral, monastery, collegiate church or parish church had originated with an Anglo-Saxon foundation. Eventually a minster came to refer more generally to "any large or important church, especially a collegiate or cathedral church". In the 21st century, the Church of England has designated additional minsters by bestowing the status on existing parish churches.
The word minster (Old English mynster) was a rendering of the Latin monasterium. In early English sources, monasterium and mynster were used interchangeably. They were applied to all communities who had devoted their lives to Christian observance, regardless of the gender of the occupants or the activities in which said occupants typically engaged.Monasterium was for instance applied equally to a small community of men living away from other secular settlements, to a large community of men and women living in a planned enclosure designed around a church, and to a widow and her unmarried daughters living in seclusion. The modern English term "monastery" does not express the same connotations as the Latin monasterium, from which it derives, or the Old English mynster. This is because the term has come to be associated with contemplative regularity, such as that observed by the Benedictine or Cisterian orders, although this does not apply to the situation in Anglo-Saxon England prior to the tenth century.
