      unendowed college).
      [1913 Webster]

   5. The apartment in which English university students dine in
      common; hence, the dinner itself; as, hall is at six
      o'clock.
      [1913 Webster]

   6. Cleared passageway in a crowd; -- formerly an exclamation.
      [Obs.] "A hall! a hall!" --B. Jonson.

Easton's 1897 Bible Dictionary:

Hall
   (Gr. aule, Luke 22:55; R.V., "court"), the open court or
   quadrangle belonging to the high priest's house. In Matt. 26:69
   and Mark 14:66 this word is incorrectly rendered "palace" in the
   Authorized Version, but correctly "court" in the Revised
   Version. In John 10:1,16 it means a "sheep-fold." In Matt. 27:27
   and Mark 15:16 (A.V., "common hall;" R.V., "palace") it refers
   to the proetorium or residence of the Roman governor at
   Jerusalem. The "porch" in Matt. 26:71 is the entrance-hall or
   passage leading into the central court, which is open to the
   sky.


Bouvier's Law Dictionary, Revised 6th Ed (1856):

HALL. A public building used either for the meetings of corporations,
courts, or employed to some public uses; as the city hall, the town hall.
Formerly this word denoted the chief mansion or habitation.
