Kazakh personal names have undergone various stages of evolution from ancient times to the present day, resulting in the formation of an integrated lexical system. This article analyzes the pathways through which these names have survived to the present and examines their etymological foundations. It demonstrates, at the phonemic level, that some variants which have diverged from one another over time originated from a common source in ancient periods. The study suggests that Personal names are presented as a means of expressing the shared historical and cultural connections among contemporary Turkic peoples. In this study attention is also paid to external factors such as the people's worldview, traditions and customs, religion, history, and social environment. The article explores issues of contemporary Kazakh anthroponymy, including the evolutionary development of Old Turkic personal names into their modern forms in Turkic and Kazakh languages, orthographic norms, their conformity to the phonological system of the Kazakh language, and the adaptation of foreign as well as Arabic-Persian names into Kazakh.
