Prior (or prioress) is an ecclesiastical title for a superior in some religious orders. The word is derived from the Latin for "earlier" or "first". Its earlier generic usage referred to any monastic superior. In abbeys, a prior would be lower in rank than the abbey's abbot or abbess. In the Rule of Saint Benedict, the term appears several times, referring to any superior, whether an abbot, provost, dean, etc. In other old monastic rules the term is used in the same generic sense. With the Cluniac Reforms, the term prior received a specific meaning; it supplanted the provost or dean (praepositus), spoken of in the Rule of St. Benedict. The example of the Cluniac congregations was gradually followed by all Benedictine monasteries, as well as by the Camaldolese, Vallombrosians, Cistercians, Hirsau congregations, and other offshoots of the Benedictine Order. Monastic congregations of hermit origin generally do not use the title of abbot for the head of any of their houses, in an effort to avoid the involvement with the world the office of an abbot would entail. As a result, it is not in use for the congregation as a whole. Among them, the equivalent term of 'prior general' is the one used. This applies, e.g., to the Camaldolese and the Carthusians. The term is also used by various mendicant orders, e.g., the Carmelites and the Dominicans. This applies both to the friars and the nuns of these orders. The term connotes the idea that the 'prior general' is simply the "first among equals". The Benedictine Order and its branches, the Premonstratensian Order, and the military orders have three kinds of priors: the claustral prior the conventual prior the obedientiary prior The Claustral prior (Latin prior claustralis), called dean in a few monasteries, holds the first place after the abbot (or grand-master in military orders), whom he assists in the government of the monastery, functioning effectively as the abbot's second-in-charge. He has no ordinary jurisdiction by virtue of his office, since he performs the duties of his office entirely according to the will and under the direction of the abbot.
