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.
Language legislation in Belgium
The second law on the use of languages in 1878 regulated the use of language in the administrations of Flanders and Brussels. Announcements to the public by government officials had to be made in either Dutch or in both languages. Correspondence with municipalities or persons would be in Dutch unless a person expressed a wish to be engaged in French but in reality the law in daily life was hardly applied: Flemish citizens were still obliged to speak French in their communications with the administration because most civil servants were monoglots who either spoke only French or refused to use the Dutch language.
