Religion

Among monastic orders, the term denotes the relation of a monastic community with a newer community which it has established elsewhere. The relationship can be that of an abbey with a priory comprised of the monks who originated from the first house. In that situation, the abbot remains the ultimate authority for the affairs of the dependent priory, which is considered an extension of the founding house. This relationship will end at such time as the daughter community might become fully autonomous and an abbey in its own right.

Smaller monasteries of nuns within a monastic congregation can make a bond with a monastery of monks within the same division of the Order, whereby the two are affiliated, and the monks guarantee pastoral care of the nuns. In this sense, the women's house is considered a dependency on that of the men.
