Eastern Turkic refers to a branch of the Turkic languages, primarily spoken in regions of Central Asia and parts of China. This group includes languages such as Uyghur, Kazakh, and Tuvan. These languages share common linguistic features and have evolved from a shared ancestral language. The Eastern Turkic languages are characterized by vowel harmony and agglutination, where suffixes are added to root words to modify their meaning. They are used by various ethnic groups, including the Uyghurs in Xinjiang, China, and the Kazakhs in Kazakhstan, reflecting the rich cultural heritage of the Turkic peoples.
