   parlatorium. See {Parley}.] [Written also {parlour}.]
   A room for business or social conversation, for the reception
   of guests, etc. Specifically:
   (a) The apartment in a monastery or nunnery where the inmates
       are permitted to meet and converse with each other, or
       with visitors and friends from without. --Piers Plowman.
   (b) In large private houses, a sitting room for the family
       and for familiar guests, -- a room for less formal uses
       than the drawing-room. Esp., in modern times, the dining

       room where visitors are received and entertained.

         recently.'' --Fitzed. Hall.
