This article examines the sociolinguistic features of the language used in contemporary Kazakh cinema and provides a scholarly rationale for the role of the Kazakh language within the film industry. The aim of the study is to identify the mixed linguistic structures characteristic of Kazakh cinema (such as code-switching, slang, jargon, pidginization, and creolization) and to determine their impact on national language policy and the public prestige of the Kazakh language. Deviations from linguistic norms recorded in cinematic works directly affect language purity, emotional connection with the audience, and the linguistic identification of youth. More than twenty comedic and dramatic films were analyzed as part of the language corpus, and a content analysis was conducted to determine the frequency of code-switching, grammatical inconsistencies, lexical hybrids, and the presence of obscene language. The relevance of this study lies in the fact that Kazakh cinema constitutes a significant component of national culture, and its language practices have a direct impact on how the language is perceived by audiences and on the development of the Kazakh language itself. In the context of globalization and increasing foreign cultural influence, the preservation and advancement of the national language face new challenges. Therefore, the language of Kazakh cinema is considered not only a creative medium but also a crucial tool for language policy and the preservation of cultural heritage. The findings of the study may be useful for screenwriters, directors, and linguists working in the field of cinema. The analysis of linguistic practices in Kazakh filmmaking can inform strategies to enhance the status of the Kazakh language, as well as its preservation and development. Additionally, the research may serve as educational material for students and scholars interested in Kazakh cinema and is aimed at expanding opportunities for linguistic revitalization through cinema, while also advancing the use of language as a means of ideological and cultural representation.
