Sogdian archetypes in Chatkal oronymy as an ancient substrate of toponyms of Central Asia

The relevance of studying the oronymy of the Chatkal area of Kyrgyzstan is associated with the fact that many mountain names are well preserved in sound and semantic terms. This factor is an important condition for studying the retrospective of any language, including the Turkic languages too. Also, in the sound shells of mountain names, despite their deep antiquity, long disappeared elements of languages that are in contact in the same linguistic area in the deep past have survived. As part of the mountain names of the Chatkal zone of the mountain ranges of Kyrgyzstan, individual morphemes and sounds of the ancient Turkic languages have been preserved, and at the same time, East Iranian topolexemes of the Indo-European language family are found. At the same time, the structure of oronyms to some extent shows the evolution of the language as a whole and of each tier in it. The history of the Kyrgyz language and its interaction with various systemic linguistic structures are reflected in the stratigraphy of oronymy. This allows you to explore the historical plan of the Turkic languages in more depth in the diachronic sense.
