\Si"zar\, n.
One of a body of students in the universities of Cambridge
(Eng.) and Dublin, who, having passed a certain examination,
are exempted from paying college fees and charges. A sizar
corresponded to a servitor at Oxford.
      The sizar paid nothing for food and tuition, and very
      little for lodging.                      --Macaulay.
Note: They formerly waited on the table at meals; but this is
      done away with. They were probably so called from being
      thus employed in distributing the size, or provisions.
