East Germanic was spoken by peoples who migrated back to southeastern Europe. No East Germanic language is spoken today, and the only written East Germanic language that survives is Gothic.
North Germanic evolved into the modern Scandinavian languages of Swedish, Danish, Norwegian, and Icelandic (but not Finnish, which is related to Estonian and is not an Indo-European language).
West Germanic is the ancestor of modern German, Dutch, Flemish, Frisian, and English.
