what language anglo saxon speak
Confidence votes 4. The Angles and the Saxons initially spoke a variety of their own languages; North Anglian, Mid Anglian, East Anglian, West Saxon, East Saxon, South Saxon etc etc. Hundreds of years later these different languages were brought together (mainly through the translation of the Bible in West Saxon) by the efforts of King Alfred the Great.
During the early migration period, the Angles would have spoken Proto-Anglian, the Saxons would have spoken Proto-Saxon, the Frisians would have spoken Proto-Frisian and the Jutes would have spoken Proto-Jutish. I use the prefix 'proto' because all of these tongues are unattested in their preliterate, continental forms.
