Flemish or Belgian Dutch (is the Dutch language as spoken in Flanders, the northern part of Belgium, be it standard (as used in schools, government and the media) or informal (as used in daily speech, "tussentaal". There are four principal Dutch dialects in Flanders: Brabantian, East Flemish, West Flemish, and Limburgish. The latter two are sometimes considered separate languages.
Limburgish and West Flemish are Lower Franconian languages that are related to Standard Dutch, but are not strictly speaking dialects of Dutch. These should not be confused with the dialects of Dutch spoken in the same provinces of Limburg and West Flanders.
Linguistically, 'Flemish' is sometimes used as a term for the language of the former County of Flanders, especially West Flemish. However, as a result of political emancipation of the Dutch-speaking part of Belgium, the combined culture of that region (which consists of West Flanders, East Flanders, Flemish Brabant, Antwerp, Limburg and Brussels) has come to be known as 'Flemish' and so sometimes are the four dialects or the common intermediate language. Despite the name, Brabantian and in particular its Antwerp dialect is the dominant contributor to the Flemish tussentaal.
