Abstract
The article deals with the peculiarities of the colloquial speech of the Kazakhs living in China in the collected materials of oral speech. The main goal is to prove the regularity of the occurrence of various phonetic, grammatical phenomena that have been preserved in colloquial speech of the Kazakhs of China and are not found in the Kazakh literary language. This process is dependent on the historical situation prevailing among Kazakhs who do not live on their territory, on the linguistic interdependence of ethnic groups living in the neighborhood, on the choice of the profession of the Kazakh language and the way they do business. The language of the Kazakhs living in China was influenced by two different factors. One of them is the external factor, that is, the influence on the development of the language of Chinese, Uigurs and Mongols living side by side with the Kazakhs, another factor is the spoken language of the Kazakhs based on the laws of the internal development of the national language. Bilingualism is characteristic of the language of the Kazakh diaspora, which can be considered as a social factor, since living in a different country implies fluency in the language of a different environment and native language. The article made a comparative analysis of the phonetic, grammatical and lexical features of colloquial speech of the Kazakh diaspora in China and speakers of the Kazakh literary language.
