The system of Kazakh anthroponyms is characterized by both regional and social pecularities. This study is devoted to the anthroponomy of Aktobe city. The proper names have vivid national and cultural semantics as their values are arbitrary from history and culture of people – native speakers. In Kazakh namegiving the loss of magical function occurs, which gives way to social and aesthetic functions. Purpose of the study. Studying the dynamics of the naive worldview in the system of Kazakh anthroponyms on the materials of Aktobe city (Kazakhstan), as well as the conceptual foundations of onomastic representation and its subsequent practical application. Methods of research. The main methods of the work are the method of contrastive-comparative analysis of linguistic units in synchrony and diachrony and the method of statistical data processing. Conclusions. In the Kazakh namegiving a gradual loss of the magical function takes place, which gives way to the social, appellative, epistemic, and aesthetic functions. In modern Kazakh women's names, just as in ancient times, the appellative function of namegiving gives way to an aesthetic function. The arsenal of modern women's names is refilled by sonorous names, borrowed from both the Eastern and Western culture. Despite the activity of the general trend in the Kazakh anthroponymic system for the transition to national forms and variants of naming (execution of surnames and patronymics in accordance with the national traditions), upon registration newborns, the Aktobe residents continue to write their names in the documents more often in Russian, which generally indicates dominance of Russian language in the Kazakh youth environment of Aktobe city.
