Priory \Pri"o*ry\, n.; pl. {Priories}. [Cf. LL. prioria. See
   {Prior}, n.]
   A religious house presided over by a prior or prioress; --
   sometimes an offshoot of, an subordinate to, an abbey, and
   called also {cell}, and {obedience}. See {Cell}, 2.

   Note: Of such houses there were two sorts: one where the
         prior was chosen by the inmates, and governed as
         independently as an abbot in an abbey; the other where
         the priory was subordinate to an abbey, and the prior
         was placed or displaced at the will of the abbot.

   {Alien priory}, a small religious house dependent on a large
      monastery in some other country.

   Syn: See {Cloister}.
