Uzbek language (O‘zbek tili) is a Turkic language, the official language of the Republic of Uzbekistan.
According to various estimates there are up to 25 million of Uzbek language carriers in the world, most of them living in Uzbekistan and consists of ethnic Uzbeks. Besides that, Uzbek language is common in Tajikistan, Kyrgyzstan, Kazakhstan, Turkmenistan, Afghanistan and Xinjiang Uygur autonomous region of China. Dialectical, that allows to attribute it to the different subgroups. Grammatically and lexically Uighur and Turkic languages of Karluk (Chagatai) group are closest relatives of modern literary Uzbek language.
Formation of the literary old Uzbek (Chagatai) language based on Karluk-Uyghur dialects of Mawarannahr (Transoxiana), which became an official in the State of Tamerlane. It refers to the XIV-XV centuries. The modern literary Uzbek language was formed on the basis of the Fergana-Tashkent group dialects. Writing in the Uzbek language existed on the Arabic basis until 1930. In the years of 1930-1939 it was on the basis of the Latin and in 1939th the Cyrillic alphabet with some additional letters started to be used. In 1993, the Uzbek language was officially transferred into the Latin alphabet.
