As someone who has watched Hercule Poirot I always understood Flemish was actually the Dutch language and that there was no such language called Belgian.
Right, Dave. There is no such language simply referred to as "Belgian."
One may refer to a "Belgian French" dialect being spoken, however.
A quick search online found:
There are 3 official languages in Belgium: Dutch, French and German.
Dutch is spoken by 60% of the people, living in the Northern Flemish region.
French is spoken by 40% of the people, living in the Southern Walloon region.
German is spoken in a small part in Eastern Wallonia.
Most people speak at least one foreign language since everyone learns the second major language on school from (at least) the age of 10. German is spoken by less than 1% of the Belgians, living in a small eastern region. Most people of the German speaking region speak both other languages as well. Also a lot of people speak English. Learning languages as German and Spanish is also popular among the general population.
In the Flemish region, Dutch is the only official language.
In the Walloon region, French is the only official language.
The Brussels Capital Region is officially bi-lingual- French/Flemish.
There is also a part of people who speak not one of the official languages. Most of them are the first generation of immigrants. Most languages in this category are Turkish, Arabic and Italian.
