obsolete, widely rejected supergroup of Turkic, Mongolic, Tungusic, Koreanic and Japonic language families
Altaic was a proposed language grouping that attempted to link together Turkic, Mongolic, Tungusic, Korean, and Japanese as related families, but this theory is now considered outdated and has been rejected by most modern linguists. It matters historically because it represents an early attempt to understand language relationships across Asia, though current scientific evidence does not support the idea that these languages share a common ancestor recent enough to demonstrate a genuine family connection.

The Altaic languages (/æl.ˈteɪ.ɪk/ , al-TAY-ik) or Altaic sprachbund are a sprachbund comprising the Turkic, Mongolic and Tungusic language families. The grouping was previously proposed as a language family, a theory which found support in the 20th century but is now rejected by many linguists, who have concluded the similarities among Turkic, Mongolic, and Tungusic languages are better explained by areal convergence rather than a shared genetic lineage. There is still, however, a significant faction of academics advocating for the language label, as the debate is still running.
These languages share agglutinative morphology, head-final word order, and some vocabulary. The once-popular theory attributing these similarities to a common ancestry has been questioned by most comparative linguists in favor of language contact, although it continues to be supported by a smaller, yet stable scholarly minority. Like the Uralic language family, which is named after the Ural Mountains, the group is named after the Altai mountain range in the center of Asia.
