Bordello is a term for a building where prostitutes meet and service their clients. It is an Italian word which originated between 1590 and 1600. Its etymology is from the Old French word bordel, meaning "wooden hut," which aptly describes the appearance of the first bordellos.
Whorehouse and brothel are common synonyms for bordello. The word bordello has fallen out of common usage although it is still used in some period novels.
