QUADR is a shortened form of the word "quadrangle," which is a noun with multiple meanings. Firstly, it can refer to a geometric shape with four sides and four angles, in which opposite sides are parallel. It is commonly known as a rectangle. Secondly, it can denote a large open area, typically a courtyard, enclosed by buildings or walls on four sides.

In this context, it reflects the idea of possessing four interrelated elements or entities.
