 This language area stretches towards the southwest along cities such as Neuss, Krefeld and Mönchengladbach, and the Heinsberg district, where it is called Limburgish, crosses the German-Dutch border into the Dutch province of Limburg, passing cities east of the Meuse river (in both Dutch and German called "Maas") such as Venlo, Roermond and Geleen, and then again crosses the Meuse between the Dutch and Belgian provinces of Limburg, encompassing the cities of Maastricht (NL) and Hasselt (B).Thus a mainly political-geographic (not linguistic) division can be made into western (Dutch) South Guelderish and Limburgish at the west side, and eastern (German) Low Rhenish and South East Low Franconian at the east side of the border.The eastmost varieties of the latter, east of the Rhine from Düsseldorf to Wuppertal, are referred to as Bergish.
