Franco-Provençal (also Francoprovençal, Patois or Arpitan) is a Gallo-Romance language that originated and is spoken in eastern France, western Switzerland, and northwestern Italy.
Franco-Provençal has several distinct dialects and is separate from but closely related to neighbouring Romance dialects (the langues d'oïl and the langues d'oc, in France, as well as Rhaeto-Romance in Switzerland and Italy).
