Modality is strongly tied to problems about the unity of language and thought, as well as language's communicative role. Sentences with the word modality in Turkic languages is still understudied, and there are a lot of controversy and unanswered issues around modality. The sentence conveys not simply a message about something, but also the speaker's perspective on it. Consequently, every sentence comprises the modality. One of the most important aspects of the phrase is its modality. The linguistic characteristics of modality in the modern Kazakh language are extremely diverse and complicated in terms of structure and composition, because language is a system. However, it is not difficult to divide them into specific stable models and present them systematically in particular models. As a result, they cannot remain impartial in the absence of such consistency. Such language models that demonstrate this range of possibilities are widely distributed in our language. The language contains language pattern models that are actively used in relation to speech possibilities. It is difficult to count them without instantly leaving a list, because communicative and stylistic interests are evolving and expanding continually, like the language itself in general. The research aim. In this work, we made an attempt to analyze modal words, which, along with introductory words and particles, correspond to the lexical-syntactic means of conveying the modality of the sentence. Our research focused on the following questions: "What is the modality in general? What are its methods of expression? By what means are the modalities of sentences expressed in the Kazakh language? Achieving the intended purpose necessitated solving the objectives:

- to determine the meanings expressed by modal verbs;

- to analyze the grammatical features of modal verbs and their distinctive features;

- to identify the essence of modal relationship (how does the speaker understand the message; how does he describe it; how does he accept the truth);

- to reveal the means of expressing modality from the point of view of their semantic and universal features;

- to establish general and specific features and differences in the means of expressing modality.

The work uses general scientific and philological methods: observation, comparison, linguistic analysis of literary text, contextual analysis and component analysis. The methodological and theoretical basis of the study were the works examining certain problems of the texts and categories of modality, set out in the works of linguists such as Palmer (2001), Vinogradov (1975) in domestic and international schools of science. The research material consists of 2000 examples, which present materials from the press and fiction, including methods of conveying subjective modal assessment. The instances extracted from the texts were analyzed, and individual language examples borrowed from theoretical and lexicographical sources were also subjected to linguistic analysis. The article's practical significance stems from the ability to use its materials and conclusion when giving grammar lectures, special translation practice courses, developing programs, educational and methodological aids, and furthering theoretical issues of modality in general. Theoretical significance provides the functional method to comprehending the meaningful character of modality. Findings. Modal words are classified into several parts of speech based on their grammatical and lexical features. They include both significant and service words. Based on real data, we found that the investigated words are distinguishable by semantic richness in expressing modal shades in the phrase. There are some modal words in Kazakh and other Turkic languages, due to the nature of their uses, however, they are extremely diverse and multifaceted, and as linguistic facts show, they can be used as synonyms in relation to one another. They also have diverse shapes. In addition to the primary meaning, they have numerous derivative meanings. Modal words that exist in a grammatical link are used in their nominative lexical meanings as independent constituents of the sentence, i.e. as a predicate; in modal meaning, they are used as one of the components of the complicated verb. The environment in which the meaning is born plays an important part in the creation of the grammatical semantics of modal verbs, and meanings within certain forms of modality are established on its foundation, including derived modal terms.
