The Tungusic languages (also known as Manchu-Tungus, Tungus) form a language family spoken in Eastern Siberia and Manchuria by Tungusic peoples. Many Tungusic languages are endangered, and the long-term future of the family is uncertain. There are approximately 75,000 native speakers of the dozen living languages of the Tungusic language family. Some linguists consider Tungusic to be part of the Altaic language family, along with Turkic, Mongolic, and sometimes Koreanic and Japonic. However, there is no consensus that Altaic is a linguistically genetic group and not a sprachbund.
