This document discusses how national identity is expressed through language and how one standard language variety is selected and promoted within a national educational system and protected through official means. This standard language then serves to distinguish insiders from outsiders. It notes that standard languages are artificially constructed from the many dialects spoken in a country and imposed as the national code. The document also discusses how languages take on symbolic value beyond practical use and become totems for cultural groups. It mentions how the dominance of one language over others can occur through deliberate political and cultural pressure, with examples given of English dominance in some contexts.
