chamber

A chamber is an enclosed space, often where a specific event usually takes place — such as a sleeping chamber or a torture chamber.

The history of the word chamber is an interesting one. The Latin word for room was camera. The original word for camera was camera obscura, or "dark chamber," since it was a big black box. Now, the word chamber can refer to any enclosed space — such as the chamber of a gun or the four chambers of your heart.
