Kypchak–Bolgar Kypchak–Cuman Kazakh–Nogay
The Kypchak languages (also known as the Kipchak, Qypchaq, or Northwestern Turkic languages), are a major branch of the Turkic language family spoken by more than twelve million people in an area spanning from Lithuania to China.
 Linguistic features
The Kypchak languages share a number of features that have led linguists to classify them together. Some of these features are shared with other Turkic languages; others are unique to the Kypchak language family.
- Change of Proto-Turkic *d to /j/ (e.g. *hadaq > ajaq "foot")
- Loss of initial *h sound (preserved only in Khalaj. See above example.)
 Unique features
- Extensive labial vowel harmony (e.g. olor vs. olar "them")
- Frequent fortition (in the form of assibilation) of initial */j/ (e.g. *jetti > ʒetti "seven")
- Diphthongs from syllable-final */ɡ/ and */b/ (e.g. *taɡ > taw "mountain", *sub > suw "water")
The Kipchak languages may be broken down into three groups, based on geography and shared features:
- Kipchak–Bolgar (Uralian, Uralo-Caspian), including Bashkir and Tatar (including Siberian Tatar, Mishar Tatar, Astrakhan Tatar, Baraba Tatar, etc.)
- Kipchak–Cuman (Ponto-Caspian), including Karachay-Balkar, Kumyk, Karaim, Krymchak, and the extinct Cuman and Kipchak[dubious ][not if it's ancestral] languages. Urum and Crimean Tatar appear to have a Kipchak–Cuman base, but have been heavily influenced by Oghuz languages.
- Kazakh–Nogay (Aralo-Caspian), including Kazakh, Karakalpak, Kyrgyz, and Nogay (also Nogai or Nogay Tatar)
