What is wc meaning?

WC is an abbreviation for Water Closet. It is commonly used in reference to a bathroom or restroom, especially in British English. The term dates back to the Victorian era when indoor plumbing became more common and toilets were first installed indoors. The term WC is used to denote a room with a toilet, sink, and often a shower or bathtub. In many countries, the term "toilet" or "lavatory" is more commonly used instead of WC.
