East Norse refers to the group of North Germanic languages spoken in the eastern regions of Scandinavia, primarily in Sweden and Denmark. It includes dialects that evolved from Old Norse, particularly the varieties that developed in these areas during the Viking Age and beyond. The two main branches of East Norse are Swedish and Danish. These languages share many similarities but have distinct phonetic, grammatical, and vocabulary differences. East Norse played a significant role in the cultural and linguistic development of the Nordic countries, influencing modern Scandinavian languages.
