Hainaut, historically also known as Heynault in English, is the westernmost province of Wallonia, the French-speaking region of Belgium.
To its south lies the French department of Nord, while within Belgium it borders (clockwise from the north) on the Flemish provinces of West Flanders, East Flanders, Flemish Brabant and the Walloon provinces of Walloon Brabant and Namur.
Picard (/ˈpɪkɑːrd/ PIK-ard, also US: /pɪˈkɑːrd, ˈpɪkərd/ pih-KARD, PIK-ərd, French: [pikaʁ] ) is a langue d'oïl of the Romance language family spoken in the northernmost of France and parts of Hainaut province in Belgium. Administratively, this area is divided between the French Hauts-de-France region and the Belgian Wallonia along the border between both countries due to its traditional core being the districts of Tournai and Mons (Walloon Picardy).
The language or dialect is referred to by different names, as residents of Picardy call it simply Picard, but in the more populated region of Nord-Pas-de-Calais it is called Ch'ti or Ch'timi (sometimes written as Chti or Chtimi). This is the area that makes up Romance Flanders, around the metropolis of Lille and Douai, and northeast Artois around Béthune and Lens. Picard is also named Rouchi around Valenciennes, Roubaignot around Roubaix.
