Fergana Kipchak language
Fergana Kipchak, also Kuman, Qomanian, or Kipchak Uzbek, is an extinct Turkic language formerly spoken in the Fergana Valley in Central Asia. It split from East Kipchak in the middle of the 8th century. Other East Kipchak dialects gave rise to the modern Kyrgyz language. In some regions of Fergana Province the features of Kipchak are seen, especially in phonetics. These regions are Baghdad, Buvayda, Uchko'prik, and some parts of neighboring regions. Many idioms spoken in Uzbekistan that are now considered part of the Kyrgyz language are actually Fergana Kipchak dialects. According to the E. D. Polivanov, the Fergana Kipchak language existed as a separate idiom as late as in the 1920s. According to A. N. Samoilovich's latest research, some descendants of Fergana Kipchaks identify themselves as a separate ethnic group independent from the Uzbeks, Kazakhs or the Kyrgyz, although closely related to the latter.
Some modern Fergana Kipchak dialects seem closely related to the Kipchak–Nogay group of the Turkic languages.
