cabaret

Cabaret traces back to Greek kamára, meaning a vaulted room, which passed into Latin as camera. From there it moved through Old Northern French and Picard forms like cambrete before arriving in Middle French as cabaret, and English borrowed the word directly from French.

The word began as a term for a simple chamber or vaulted space, then narrowed over its journey through French into meaning a small tavern or drinking room, before English adopted it for the entertainment venue sense we know today.

Cabaret shares its deep root with camera — both descend from the Latin word for a vaulted room, though camera went on to mean a chamber in a very different, image-capturing sense.
