Query: What's another name for Old Frisian?
Context: The latter would as a consequence evolve with Allemanic into Old High German. At more or less the same time the Ingvaeonic nasal spirant law led to the development of Old Saxon, Old Frisian (Anglo-Frisian) and Old English (Anglo-Saxon). Hardly influenced by either development, Old Dutch remained close to the original language of the Franks, the people that would rule Europe for centuries.
