what is a wc

WC is an abbreviation for "water closet". It is a term used to refer to a toilet or a room containing a toilet. The term originated in the 1900s when most toilets were fitted in a spare closet or cupboard, hence the name "water closet". Over time, the term WC has been used instead of bathroom to describe a room with a toilet but no bath. The term is still used today, especially on signs or in advertisements for houses, flats, or hotels.
