A study is a room in a house that is used for paperwork, computer work, or reading. Historically, the study of a house was reserved for use as the private office and reading room of a family father as the formal head of a household, but today studies are generally either used to operate a home business or else open to the whole family.
A typical study might contain a desk, chair, computer, desk lamps, bookshelves, books, and file cabinets. A spare bedroom is often utilized as a study, but many modern homes have a room specifically designated as a study. Other terms used for rooms of this nature include den, home office, or library.
