Nowadays, when the importance of language culture and competent communication increases, maintaining the accuracy of the word is one of the important linguostylistic requirements. The article is devoted to the problem of paronymy, the nature of which has not yet been specifically studied in Kazakh linguistics. In the modern linguistic space, the inability to correctly use paronyms has become a common phenomenon, leading to stylistic and semantic errors not only in colloquial speech, but also in official, scientific, journalistic and artistic texts. The purpose of this research work is to clarify the nature of paronymic words in the Kazakh language, determine their meaning and stylistic nuances, as well as functional characteristics. To achieve this goal, the following tasks were set: to review the study of word pairs recognized as paronyms in foreign and Kazakh linguistics, analyze the semantic and stylistic features of paronyms in the Kazakh language, suggest ways of their correct use, show their similarity and difference with other similar lexical and semantic groups in our language, analyze their use in accordance with the norms of the literary language, as well as frequently encountered errors that arise due to the inability to distinguish them. As a result of the study, a review of research works was conducted, examples of paronymic pairs recognized as paronyms in our language were given, and the reasons for their incorrect use were identified. In addition, specific examples of incorrect use were given that undermine linguistic accuracy, and ways to correct them were proposed. The article analyzed the opinions of journalists and scientists M. Balakayev, R. Syzdyk, N. Shakeev and H. Nurmukhanov on the need to stabilize and clarify the meanings of such pairs of words with different meanings but similar pronunciation, which cause difficulties in our language, and presented scientifically substantiated proposals aimed at improving language culture. It was concluded that lexical units recognized as paronyms are not only the result of colloquial speech, but can be considered as a lexical-semantic group with its own characteristics and belonging to the language system. The article uses comparative, semantic-stylistic, and in some cases etymological and lexicographic methods of analysis to identify the semantic, stylistic and functional features inherent in each of the paronymic pairs.
