Estonian Swedish
Estonian Swedish (Swedish: estlandssvenska; Estonian: rannarootsi keel, lit. 'Coastal Swedish') are the eastern varieties of the Swedish language that were until the mid-20th century spoken in the Aiboland, the coastal areas and islands of western and northern Estonia which had been inhabited since the Middle Ages by the Estonian Swedes. Until the evacuation of the Estonian Swedes near the end of World War II, both Swedish and Estonian were commonly spoken in the Aiboland coastal areas and islands.
