Old Frisian is a West Germanic language that was spoken in the northern part of the Netherlands and northwestern Germany from the 8th to the 16th century. It is also referred to as Anglo-Frisian or West Frisian due to its close relation to Old English and Old Saxon. Some synonyms for Old Frisian include Old East Frisian, Old Low Franconian, and Old West Low German. The language was primarily written in the Latin alphabet and had a significant influence on the development of the modern Frisian language. Despite its dissolution as a spoken language, Old Frisian remains an important part of the region's cultural history and linguistic heritage.
