STUDENT UNION

The term 'student union' can be used in either of two senses:

★ 'Students' union', a student organization at many colleges and universities dedicated to student governance (not common in USA, see below)

★ 'Student activity center', a building that typically hosts a "union" of student services (e.g., food service, health facilities, lounges) at such institutions (also know as a "student center" or "student commons")
In the United States, the phrase more commonly refers to the building. The phrase "student government" or "student senate" is usually used when referring to the subject of the "Students' union" article.
