Aunis in the context of "Châtelaillon-Plage"

Poitou-Charentes (French pronunciation: [pwatu ʃaʁɑ̃t] ; Occitan: Peitau-Charantas; Poitevin-Saintongeais: Poetou-Chérentes) was an administrative region on the southwest coast of France. It comprised four departments: Charente, Charente-Maritime, Deux-Sèvres and Vienne. It included the historical provinces of Angoumois, Aunis, Saintonge and Poitou.

Poitiers was the regional capital. Other important cities were La Rochelle, Niort, Angoulême, Châtellerault, Saintes, Rochefort and Royan.

Saintongeais (French pronunciation: [sɛ̃tɔ̃ʒɛ] ; endonym: séntunjhaes) is a dialect of Poitevin–Saintongeais spoken halfway down the western coast of France in the former provinces of Saintonge, Aunis and Angoumois, all of which have been incorporated into the current departments of Charente and Charente-Maritime as well as in parts of the neighbouring department of Gironde and a town in Dordogne. Although many of the same words are used in both Charente departments, they differ in what they mean or in how they are pronounced.

Saintongeais, which is a langue d'oïl variety, and Gascon, which is a langue d'oc variety, have significantly influenced the Acadian and Cajun dialects of French spoken in Canada and the United States respectively.
