Kazakh or Qazaq (Latin: or , Cyrillic: or , Arabic Script: or , , ) is a Turkic language of the Kipchak branch spoken in Central Asia by Kazakhs. It is closely related to Nogai, Kyrgyz and Karakalpak. It is the official language of Kazakhstan and a significant minority language in the Ili Kazakh Autonomous Prefecture in Xinjiang, north-western China and in the Bayan-Ölgii Province of western Mongolia. The language is also spoken by many ethnic Kazakhs throughout the former Soviet Union (some 472,000 in Russia according to the 2010 Russian Census), Germany, and Turkey. Like other Turkic languages, Kazakh is an agglutinative language and employs vowel harmony. Ethnologue recognizes three mutually intelligible dialect groups, Northeastern Kazakh, the most widely spoken variety which also serves as the basis for the standard language, Southern Kazakh and Western Kazakh. The language share a degree of mutual intelligiblity with closely related Karakalpak while its Western dialects maintain limited mutual intelligibility with Altai languages. In October 2017, Kazakh president Nursultan Nazarbayev decreed that the writing system would change from using Cyrillic to Latin script by 2025. The proposed Latin alphabet has been revised several times and as of January 2021 is close to the inventory of the Turkish alphabet, though lacking the letters C and Ç and having four additional letters: Ä, Ñ, Q and Ū (though other letters such as Y have different values in the two languages). It is scheduled to be phased in from 2023 to 2031. Geographic distribution Speakers of Kazakh (mainly Kazakhs) are spread over a vast territory from the Tian Shan to the western shore of the Caspian Sea. Kazakh is the official state language of Kazakhstan, with nearly 10 million speakers (based on information from the CIA World Factbook on population and proportion of Kazakh speakers). In China, nearly two million ethnic Kazakhs and Kazakh speakers reside in the Ili Kazakh Autonomous Prefecture of Xinjiang. History The first people to inhabit the territory of modern Kazakhstan were the Scythians, who were of Iranian descent. The Göktürks migrated into the area in the sixth century AD and conquered much of the Scythian homeland, which led to the Turkification of the region. In the 12th century AD, the Kimeks later succeeded the Göktürks and also introduced a new Turkic tongue to the Kazakh steppe. The Kipchak branch of Turkic languages, which Kazakh is borne out of, was mainly solidified
