THE USE OF ADVERBS IN THE «CODEX CUMANICUS» MANUSCRIPT

The article aims to identify the formation of a system of morphological changes of adverbs in the modern Kazakh language. To achieve this goal, the following tasks are set: to distinguish lexical and semantic groups, to determine the use of adverbs in the «Codex Cumanicus» manuscript, to identify the influence of centuries-old language development on the lexical composition of words and the processes of acquiring various forms by the modern Kazakh language, depending on the communicative function and meaning in other Turkic languages. Depending on the goals and features of the work, methods of description, comparison, contrast, structural, synchronous and diachronic analysis, generalization, systematization were used. As a result, the stages of formation of the system of morphological changes of adverbs are determined, lexico-semantic groups are differentiated, individual features are described. Comprehensively analyzing the conclusions that adverbs have the main feature – immutability in all Turkic languages, it is proved that the ongoing evolution and various development processes in the language also affect adverbs, acquiring various forms depending on the communicative function and meaning in modern Kazakh and Turkic languages. The results of the research are aimed at the implementation of actual problems, theoretical and applied problems in the history of language, comparative grammar and historical word formation, etc. The result of determining the use of the class of adverbs in the «Codex Cumanicus» manuscript is the theoretical basis for the historical systematization of the features of the origin, development, lexico-semantic, morphological and syntactic features of other parts of speech. On this side, this research work can be aimed at solving topical problems in the field of historical grammar, expanding the field of general and applied linguistics, systematization of opinions related to the history of language.
