Piedmontese is a Gallo-Italic language, which means it belongs to the branch of Romance languages that evolved from Vulgar Latin in the northern Italian region of the Po Valley. It's closely related to other Gallo-Italic languages like Lombard, Emilian, and Ligurian.
While Piedmontese is the most widely spoken language in the region, there are also pockets of other languages spoken in the Piedmont, such as:
* French: Due to its proximity to France, French has historically been spoken in some areas of the Piedmont, particularly in the western part of the region.
* Occitan: Another Romance language closely related to French, Occitan is spoken in a small area near the border with France.
* German: Some small communities in the Piedmont speak German, particularly in the valleys of the Alps.
Overall, the Piedmont's linguistic diversity is a reflection of its complex history and geographical location.
