Si"zar, n.
Definition: 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. See 4th Size, 2.
