Poitevin (Poetevin) is a language spoken in Poitou, France. It is one of the regional languages of France and is not as commonly spoken as it once was, as the standard form of French now predominates. Poitevin is now classified as one of the langues d'oïl but is distinguished by certain features of the langue d'oc. The language is spoken on what was the border between the two language families of oïl and oc (placenames in the region clearly show historical settlement of oc speakers).
