What is the area called backstage where actors wait when they are not performing?

The term "green room" refers specifically to the area backstage where actors wait when they are not performing. This space is often designed for relaxation and preparation, providing a comfortable environment for performers to unwind or prepare just before going on stage. The name originated historically, with various theories about its origins; however, it has become a standard term in theater terminology.

The other terms have specific meanings that differentiate them from the green room. The "backstage area" is a general term that encompasses all areas not visible to the audience, but it does not denote the specific space for actors. "Wings" refer to the sides of the stage where actors enter and exit, and they are not meant for prolonged waiting or resting. A "changing room" is typically designated for costume changes and may not possess the same relaxed atmosphere or multifunctional use as the green room. Thus, the distinction of the green room as a waiting area specifically for actors makes it the correct answer.
