The Frisian languages 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. However, modern English and Frisian are not mutually intelligible, nor are Frisian languages intelligible among themselves, owing to independent linguistic innovations and foreign influences.
