Knowra Altaic languages Altaic languages Altaic is a disputed proposed language family linking Turkic, Mongolic, and Tungusic languages, sometimes expanded to include Koreanic and Japonic. Its proposed relationships remain controversial because shared features may reflect contact rather than common ancestry.
Proto-Altaic : A reconstructed ancestor proposed for the languages grouped in the Altaic hypothesis. Its reconstruction is the central historical claim made by proponents of Altaic unity.
Turkic languages : A language family spoken across a broad area from eastern Europe and Anatolia to Siberia and western China. Turkic is one of the three core branches in the narrower Altaic proposal.
Sound correspondence : A regular relationship between sounds in words with the same historical origin across languages. Proposed Altaic cognates require systematic correspondences, not merely similar-sounding words.
Turkic–Mongolic language contact : The long-term interaction between Turkic- and Mongolic-speaking communities and their languages. Contact-driven similarities challenge the claim that shared traits necessarily reflect common descent.
Altaic hypothesis : The proposal that Turkic, Mongolic, and Tungusic languages, sometimes with Koreanic and Japonic, share a common ancestor. This name foregrounds the disputed genealogical claim behind the family label.
Mongolic languages : A language family centered in Mongolia and neighboring parts of northern and eastern Asia. Mongolic is another core branch whose relationship to Turkic and Tungusic is disputed.
Cognate : A word in one language that descends from the same ancestral word as a word in another language. Cognates provide evidence of shared descent when their sound histories are regular.
Transeurasian languages : A proposed grouping of Turkic, Mongolic, Tungusic, Koreanic, and Japonic languages, also called Macro-Altaic. This newer framing often advances a related hypothesis while emphasizing a broader set of languages.
Ural-Altaic languages : A historical hypothesis grouping Uralic and Altaic languages into a single family. This older proposal shows how the Altaic idea once expanded beyond its current scope.
Tungusic languages : A language family spoken mainly in Siberia and northeastern China. Tungusic completes the traditional three-branch version of the proposed family.
