Brabantian or Brabantish, also Brabantic or Brabantine, is a dialect group of the Dutch language. It is named after the historical Duchy of Brabant, which corresponded mainly to the Dutch province of North Brabant, the Belgian provinces of Antwerp and Flemish Brabant as well as the Brussels-Capital Region and the province of Walloon Brabant. Brabantian expands into small parts in the west of Limburg, and its strong influence on the Flemish dialects in East Flanders weakens toward the west. In a small area in the northwest of North Brabant (Willemstad), Hollandic is spoken. Conventionally, the Kleverlandish dialects are distinguished from Brabantian, but for no reason other than geography.
