A '''language''' is a method of [[communication]]. [[Human]] spoken and written languages can be described as a [[system]] of [[symbol]]s (sometimes known as [[lexeme]]s) and the [[grammar]]s ([[wiktionary:rule|rule]]s) by which the symbols are manipulated. The word "language" is also used to refer to common properties of languages.
