THE RELATIONSHIP BETWEEN DIALECT AND LITERARY LANGUAGE IN THE HISTORY OF THE UZBEK LANGUAGE: HISTORICAL-LINGUISTIC ANALYSIS

This study is devoted to the analysis of the complex and multifaceted relationship between dialects and the literary language in the history of the Uzbek language based on a historical-linguistic approach. The study considers dialects as an important source in the formation and development of the Uzbek literary language, and the influence of their phonetic, lexical and grammatical features on the norms of the literary language is consistently highlighted. The work provides a comparative analysis of written sources of the ancient Turkic period, samples of the old Uzbek literary language and modern dialect materials, paying special attention to the issues of historical continuity and coherence. Also, the role of regional dialects in the formation of literary language norms, the processes of their selection and assimilation into the national language are studied in connection with sociolinguistic factors. The results of the study show that the interaction between dialects and the literary language is not a one-sided, but a dynamic and complex process. This scientific work serves as a theoretical and practical basis for a deeper understanding of the laws of the historical development of the Uzbek language, as well as for improving literary language norms and the effective use of dialect materials.本研究依托历史语言学（historical-linguistic）方法，系统分析乌兹别克语发展史上方言与文学语言之间复杂多元的互动关系。研究将方言视为乌兹别克文学语言形成与发展的重要来源，并系统阐明其语音、词汇与语法特征对文学语言规范的影响。本研究对古代突厥时期的书面文献、古乌兹别克文学语言样本以及现代方言资料开展比较分析，重点关注历史传承性与连贯性相关问题。此外，本研究还结合社会语言学（sociolinguistic）因素，探讨区域方言在文学语言规范形成过程中的作用，以及方言特征被遴选并融入民族语言的具体进程。研究结果表明，方言与文学语言之间的互动并非单向过程，而是一个动态且复杂的过程。本学术研究可为深入理解乌兹别克语历史发展规律、完善文学语言规范以及高效利用方言资料提供理论与实践基础。
