Dungan is a Sinitic language spoken primarily in Kazakhstan, Russia and Kyrgyzstan by the Dungan people, an ethnic group related to the Hui people of China. Although it is derived from the Central Plains Mandarin of Gansu and Shaanxi, it is written in Cyrillic and contains loanwords and archaisms not found in other modern varieties of Mandarin.

The Sinitic languages, often synonymous with the Chinese languages, are a group of East Asian analytic languages that constitute a major branch of the Sino-Tibetan language family. It is frequently proposed that there is a primary split between the Sinitic languages and the rest of the family. This view is rejected by a number of researchers but has found phylogenetic support among others. The Macro-Bai languages, whose classification is difficult, may be an offshoot of Old Chinese and thus Sinitic; otherwise Sinitic is defined only by the many varieties of Chinese unified by a shared historical background, and usage of the term "Sinitic" may reflect the linguistic view that Chinese constitutes a family of distinct languages, rather than variants of a single language.
