The relevance of the study is that specific individual linguistic customs and traditions are characteristic of each nation. The objective of the study is to examine the key aspects of anthroponyms and the methodology of their development in Turkish and Kazakh languages. In conducting the research, general scientific and special methods were used to achieve its goals and objectives. Its main results can be defined as follows. It was argued that the lexical-semantic approach to word formation is one of the (...) most widespread approaches to the creation of meaningful anthroponyms, reflecting the features and characteristics of the named person. According to the results of the conducted research, the necessity of studying anthroponyms and word formations was revealed and substantiated. The reason for this is that they have an important social and cultural significance in the process of interaction between the peoples of the world, as well as the study of their cultural heritage. The latter is directly related to the fact that personal names express moral and philosophical values of a certain ethos, fix in themselves the history, traditions, and beliefs of a particular society or community. As a result of the research, it was concluded that anthroponyms in the onomastic field of any language of the world are nuclear constituents. At the same time, the whole set of anthroponyms contained in it will be unique, as the factors influencing the speakers of the language will differ. (shrink)
