Languages of Belgium
Dutch is the official language of the Flemish Community and the Flemish Region (merged to Flanders) and, along with French, an official language of the Brussels-Capital Region. The main Dutch dialects spoken in Belgium are Brabantian, West Flemish, East Flemish and Limburgish. All these are spoken across the border in the Netherlands as well, and West Flemish is also spoken in French Flanders. Much like English, Flemish dialects have adopted much more French and other Romance vocabulary through mutual cultural exchange throughout history when compared with other Dutch dialects and as such they are not always readily intelligible for Dutch speakers outside Flanders. Words which are unique to Belgian Dutch are called "belgicisms" (as are words used primarily in Belgian French). The original Brabantian dialect of Brussels has been very much influenced by French. It is now spoken by a minority in the Capital region since the language of most inhabitants shifted during the Frenchification of Brussels.
Communities, regions and language areas of Belgium
The Brussels-Capital Region (, , ) or Brussels Region is centrally located and completely surrounded by the province of Flemish Brabant and thus by the Flemish Region. With a surface area of , or 0.53% of Belgium, it is the smallest of the three regions. It contains the City of Brussels, which acts both as federal and regional capital, and 18 other municipalities. Its official languages are both Dutch and French. In the region ±78% speak French at home and ±22% speak Dutch, although a significant number of people combine these two languages. The Brussels Capital Region contains only one administrative arrondissement, the Arrondissement of Brussels-Capital. However, for juridical purposes, it forms an arrondissement with surrounding Flemish areas, the arrondissement of Brussels (equivalent in area to the former electoral district of Brussels-Halle-Vilvoorde).
