Ile-de-France (“Isle of France”) – the area around Paris, it was called so since the X century, when it became the domain of the French kings. Languedoc (the language in which the word “ada” is pronounced ok) is the name of Southern France. In the north, the word “yes” was pronounced oil, later ui. The inhabitants of the North and South belonged to different branches of the Catholic civilization – Germanic and Italian; they did not merge together until the unification of school education in the 19th century.
