The Kipchak languages (also known as the Kypchak, Qypchaq, or Northwestern Turkic languages) are a branch of the Turkic language family spoken by more than twelve million people in an area spanning from Lithuania to China.

The Kipchak 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.)

• Extensive labial vowel harmony (e.g. olor vs. olar "them") ^{[citation needed]}
• 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:^[1]

• Kipchak–Bulgar (Uralian, Uralo-Caspian): Bashkir and Tatar
• Kipchak–Cuman (Ponto-Caspian): Karachay-Balkar, Kumyk, Karaim, Krymchak. Urum and Crimean Tatar appear to have a Kipchak–Cuman base, but have been heavily influenced by Oghuz languages.
• Kipchak–Nogay (Aralo-Caspian): Nogay (also Nogai or Nogay Tatar), Karakalpak and Kazakh.
• Kyrgyz–Kipchak: Kyrgyz and Southern Altai.

The language of the Mamluks in Egypt appears to have been a Kipchak language, probably one belonging to the Kipchak-Cuman group.
