“Belgium has a large chassidic population and I think they speak french there”
Actually in Antwerp, the language is Dutch. (The Belgian version of Dutch is called Flemish – it relates to Dutch Dutch like Australian English relates to US English, meaning you can hear the difference but it’s still obviously the exact same language.) Though the frum community in Antwerp do speak a lot of French as well. But the general language of Antwerp – and the majority of Belgium, known as Flanders – is Dutch. The minority, in the southern part, called Wallonia, is French-speaking.
