Abstract
The study of the relationship between language and creativity not only reveals the mechanisms of creative thinking in various domains but also becomes relevant in the modern context. Understanding the impact of language on the formation of a creative personality is crucial for developing educational methods aimed at supporting creative abilities. This study aims to identify the connection between the diversity of lexical composition and creative potential. The research relies on an empirical basis, which includes the analysis of quantitative and substantive features of the lexical richness of well-known creative individuals in Kazakhstan, as well as its comparison with representatives of professions unrelated to creativity. During the study, three main psycholinguistic parameters of a creative personality were identified: syntactic flexibility, metaphorical thinking, and lexical repertoire. Syntactic flexibility reflects the ability to express the same idea using various syntactic constructions. Metaphorical thinking involves the skill of incorporating metaphors into speech, contributing to the formation of new associations. Lexical repertoire encompasses a multitude of words that an individual possesses and can operate in their speech. The research, based on empirical data, revealed that creative individuals in the arts have a more extensive lexical repertoire compared to representatives of non-creative professions, as confirmed by quantitative indicators. A qualitative analysis of the frequency of nouns and verbs usage also showed that creative personalities more often use terms related to creativity and abstract concepts, while representatives of non-creative professions tend to focus on more concrete topics related to work activities. The study has practical value, providing a foundation for the development of educational programs aimed at fostering creativity and shaping creative abilities in various fields of human activity.
