Old Saxon, also known as Old Low German, is a Germanic language and the earliest recorded form of Low German. It belongs to the West Germanic branch and is most closely related to the Anglo-Frisian languages. It is documented from the 8th century until the 12th century, when it evolved into Middle Low German. It was spoken on the north-west coast of Germany and in the Netherlands by Saxon peoples. It is close enough to Old Anglo-Frisian (Old Frisian, Old English) that it partially participates in the Ingvaeonic nasal spirant law; it is also closely related to Old Dutch.
