Classification

Lars Johanson's proposal contains the following subgroups:^[1][2]

• Southwestern Common Turkic (Oghuz)
• Northwestern Common Turkic (Kipchak)
• Southeastern Common Turkic (Karluk)
• Northeastern Common Turkic (Siberian)
• Arghu (Khalaj)

In that classification scheme, Common Turkic is opposed to the Oghuric languages (Lir-Turkic). The Common Turkic languages are characterized by sound correspondences such as Common Turkic š versus Oghuric l and Common Turkic z versus Oghuric r.

Siberian Turkic is split into a "Central Siberian Turkic" and "North Siberian Turkic" branch within the classification presented in Glottolog v4.8.^[3]

In other classification schemes (such as those of Alexander Samoylovich and Nikolay Baskakov), the internal classification is different.^[4][5]
