Apartment
An apartment (US English) or flat (British English) is a place to live that is only part of a larger building. Usually it is a group of rooms on one floor of a building in a city, where land is too expensive for people to have separate houses. An apartment that people own is called a condominium or "condo". A lesser known ownership structure for apartments is housing cooperatives. A rented has an owner called a landlord who charges money ("rent money" or "rent") from the people who live there ("tenants").
