Abstract
There are names of people who have preserved their ancient identity from ancient Turkic times to the present day. In the article they are considered as elements that make up the “anthroponymic foundations”. On the other hand, these stable anthroponymic components, continuing continuously from century to century, are an indicator of lexical continuity. For example, one component combines different words and creates new names in the form: in ancient times Er Togmysh, in the 15th century Erkutlyk, now Ernur and others, that is, the Er component is stable and flexible to change in accordance with the requirements of each era. Taking into account the peculiarities of this phenomenon when creating anthroponyms, the article compares old and new names, the author concludes that this issue should be taken into account when creating a dictionary of Kazakh names.
