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.
Football in Belgium
A Belgian club's name usually includes the name of the town where the club plays as well as a prefix and/or suffix. Since Belgians speak three languages, French and Dutch being the main ones and German being the third official language, Belgian teams may use either language as the basis for their names. For historical reasons, many Flemish clubs changed their names from French to Dutch between the beginning of the 20th century and the late 1960s. Additionally, many clubs have experienced frequent name changes. Reasons for these include a language change, a merger, an anniversary, etc. Because of the numerous mergers between Belgian clubs, team names sometimes combine several town names (such as K. Beringen-Heusden-Zolder or Sporting West Ingelmunster-Harelbeke) which reflect mergers. In recent history, clubs representing immigrant communities have come into existence and sometimes use names that are in neither of Belgium's official languages (the now defunct clubs Türkgucun Ozburun and Türkiyemspor Zaventem, or the still-existing Agrupación Oviedo-Asturiana, existing only in a league outside the Belgian FA now, from Brussels, being examples).
