Old Saxonとは

Old Saxon, also known as Old Low German, is the earliest recorded form of Low German, 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 Low Franconian ("Old Dutch"). It is separated from Old High German by the High German consonant shift. It was mutually intelligible with Old English.
