French Flemish

Unbeknown to many, there is a small part of France where Dutch is spoken, or better, the local dialect of French Flemish. 

Place names attest to Flemish having been spoken since the 8th century in the part of Flanders that was ceded to France at the 1659 Treaty of the Pyrenees, and which hence became known as French Flanders. Its dialect subgroup became a minority dialect that survives mainly in Dunkirk (Duinkerke in Dutch, Duunkerke in West Flemish, "dune church"), Bourbourg (Broekburg in Dutch), Calais (Kales), Saint-Omer (Sint-Omaars), with its Flemish ethnic enclave of Haut-Pont (Haute-Ponte), and Bailleul (Belle).

French Flemish has about 20,000 daily users, and twice that number of occasional speakers. The dialect's status appears to be moribund, but there has been an active movement to retain French Flemish in the region.

The video, by Mark Ingelaere, is about local farmer and boinero Maxime, but even for a native Dutch speaker like myself, close to impossible to follow. 

Merci, Frans
