the language of the Kara-Kalpaks, the main population of the Kara-Kalpak ASSR; Kara-Kalpaks also live in Khorezm and Fergana oblasts of the Uzbek SSR, Tashauz Oblast of the Turkmen SSR, the Kazakh SSR, and Afghanistan. Kara-Kalpak is spoken by 228, 000 persons (1970 census). It belongs to the Kipchak group of Turkic languages. The principal dialects are northeastern and southwestern.
Kara-Kalpak is grouped with Nogai and Kazakh because of the characteristic replacement of Common Turkic č and š by Kara-Kalpak sh and s, respectively (Kara-Kalpak kash-, “to run away,” instead of Common Turkic kač-, and bas, “head,” instead of baš). The Kara-Kalpak literary language formed after the Great October Socialist Revoltion. The Kara-Kalpak writing system was based on the Arabic alphabet until 1928, on the Roman alphabet from 1928 to 1940, and on the Russian alphabet since 1940.
