Düne in the context of "Frisian languages"

The Frisian languages (/ˈfriːʒən/ FREE-zhən or /ˈfrɪziən/ FRIZ-ee-ən) are a closely related group of West Germanic languages, spoken by about 400,000 Frisian people, who live on the southern fringes of the North Sea in the Netherlands and Germany. The Frisian languages are the closest living language group to the Anglic languages; the two groups make up the Anglo-Frisian languages group and together with the Low German dialects these form the North Sea Germanic languages. Despite the close genetic relationship between English and Frisian, the modern languages are not mutually intelligible. Geographical and historical circumstances have caused the two languages to drift apart linguistically.

Frisian is traditionally divided into three branches often labeled distinct Frisian languages even though the dialects within each branch are not necessarily mutually intelligible. West Frisian is by far the most spoken of the three and is an official language in the Dutch province of Friesland, where it is spoken on the mainland and on two of the West Frisian Islands: Terschelling and Schiermonnikoog. It is also spoken in four villages in the Westerkwartier of the neighbouring province of Groningen. North Frisian, the second branch, is spoken in the northernmost German district of Nordfriesland in the state of Schleswig-Holstein, on the North Frisian mainland and on the North Frisian Islands of Sylt, Föhr, Amrum, and the Halligs. It is also spoken on the islands of Heligoland and Düne in the North Sea. The third Frisian branch, East Frisian, has only one remaining variant, Sater Frisian, spoken in the municipality of Saterland in the Lower Saxon district of Cloppenburg. Surrounded by bogs, the four Saterlandic villages lie just outside the borders of East Frisia, in the Oldenburg Münsterland region. In East Frisia proper, East Frisian Low Saxon is spoken today, which is not a Frisian language, but a variant of Low German/Low Saxon.
