A campus is traditionally the land on which a college or university and related institutional buildings are situated. It usually includes libraries, lecture halls, residence halls, student centers, etc.
It comes from a Latin word for "field" and was first used to
describe the grounds of the College of New Jersey (now Princeton
University) during the 18th century. Other American colleges later
adopted the word to describe individual fields at their own
institutions. A school has multiple spaces, such as a campus, a
field, a yard, etc.
