any decorative textile normally made of a thick material and now usually intended as a floor covering. Until the 19th century the word carpet was used for any cover, such as a table cover or wall hanging; since the introduction of machine-made products, however, it has been used almost exclusively for a floor covering. Both in Great Britain and in the United States the word rug is often used for a partial floor covering as distinguished from carpet, which frequently is tacked down to the floor and usually covers it wall-to-wall. In reference to handmade carpets, however, the names rug and carpet are used interchangeably.
