Dialects

Dutch dialects are primarily the dialects that are both related with the Dutch language and are spoken in the same language area as the Dutch standard language. Although heavily under the influence of the standard language, some of them remain remarkably diverse and are found in the Netherlands and in the Brussels and Flemish regions of Belgium. The areas in which they are spoken often correspond with former mediaeval counties and duchies. The Netherlands (but not Belgium) distinguishes between a dialect and a streektaal (" regional language "). Those words are actually more political than linguistic because a regional language unites a large group of very different varieties. Such is the case with the Gronings dialect, which is considered a variety of the Dutch Low Saxon regional language, but it is relatively distinct from other Dutch Low Saxon varieties. Also, some Dutch dialects are more remote from the Dutch standard language than some varieties of a regional language are. Within the Netherlands, a further distinction is made between a regional language and a separate language, which is the case with the (standardised) West Frisian language. It is spoken alongside Dutch in the province of Friesland.

Dutch dialects and regional languages are not spoken as often as they used to be, especially in the Netherlands. Recent research by Geert Driessen shows that the use of dialects and regional languages among both Dutch adults and youth is in heavy decline. In 1995, 27 percent of the Dutch adult population spoke a dialect or regional language on a regular basis, but in 2011, that was no more than 11 percent. In 1995, 12 percent of children of primary school age spoke a dialect or regional language, but in 2011, that had declined to four percent. Of the officially recognised regional languages Limburgish is spoken the most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon the least (adults 15%, children 1%). The decline of the West Frisian language in Friesland occupies a middle position (adults 44%, children 22%). Dialects are most often spoken in rural areas, but many cities have a distinct city dialect. For example, the city of Ghent has very distinct "g", "e" and "r" sounds that greatly differ from its surrounding villages. The Brussels dialect combines Brabantian with words adopted from Walloon and French.

Some dialects had, until recently, extensions across the borders of other standard language areas. In most cases, the heavy influence of the standard language has broken the dialect continuum. Examples are the Gronings dialect spoken in Groningen as well as the closely related varieties in adjacent East Frisia (Germany). Kleverlandish is a dialect spoken in southern Gelderland, the northern tip of Limburg, and northeast of North Brabant (Netherlands), but also in adjacent parts of North Rhine-Westphalia (Germany). Limburgish (Limburgs) is spoken in Limburg (Belgium) as well as in the remaining part of Limburg (Netherlands) and extends across the German border. West Flemish (Westvlaams) is spoken in West Flanders, the western part of Zeelandic Flanders and also in French Flanders, where it virtually became extinct to make way for French.
