The Anglo-Frisian languages (also known as Ingvaeonic languages, North Sea Germanic languages or sometimes Insular Germanic) are a group of West Germanic languages consisting of Old English, Old Frisian, and their descendants. The Anglo-Frisian family tree is:

• Anglo-Frisian
  • Anglic languages
    • Old English
    • Middle English
    • Early Modern English
    • Modern English
    • Scots
    • Yola
  • Frisian languages
    • West Frisian
    • Saterland Frisian (also called East Frisian)
    • North Frisian

The Anglo-Frisian languages are distinguished from other West Germanic languages partially by the Ingvaeonic nasal spirant law and by the palatalization of Proto-Germanic to a coronal affricate before front vowels: cf. English cheese and Frisian tsiis to Dutch kaas and German Käse, or English church and Frisian tsjerke to Dutch kerk and German Kirche. Early Anglo-Frisian formed a Sprachbund with Old Saxon, which is counted among the Low German languages.

Note that West Flemish, a dialect of Dutch spoken in the Belgian province of West-Flanders, has also got a great deal of the Ingvaenonic characteristics.
