quadrangle

A quadrangle is a four-sided polygon, like a square or rectangle. On a college campus, the quadrangle could be the grassy rectangular space between dorms, where co-eds throw Frisbees and flirt.

Most college campuses have at least one quadrangle, a rectangular public area made cozy by surrounding buildings. The college quadrangle is almost always referred to as the quad, and this has been true since the 1820s when it became popular slang at Oxford University. The Late Latin quadrangulum, or "four-sided figure," inspired the word quadrangle.
