ETHNOCULTURAL ASPECT OF SUBSTRATE TOPONYMY OF EASTERN TRANSBAIKALIA

The toponymy of Eastern Transbaikalia is distinguished by the presence of an identified and described state of toponymic substrate layers, associated, among other things, with the Dagur substrate. When describing Dagur-language toponyms in the toponymy of Eastern Transbaikalia, research attention is focused on information of ethnocultural origin, namely, the presence of towns/fortifications according to the results of the regional toponymy. Tasks of a particular nature are attempts to describe the historical and ethnographic aspects of Dagur toponyms, thereby connecting both the meaning of the studied toponyms with historical realities, and a kind of “reconstruction” of the historical past of the peoples of historical Dauria through toponymy, starting with the concept of "Dauria". In this regard, we connect both the meaning of the studied toponyms with historical realities, and by "reconstructing" the historical past of the peoples of historical Dauria through toponymy, starting with the concepts of "Dauria", "Selenga Dauria", 'Nerchinsk Dauria". Firstly, the etymologies of a number of oikonyms have been given, which in lexico-semantic terms are directly related to the naming of settlements from the vocabulary of the Dagur language - tors 'village, village' and "remaining" in the name Taras(s) in the works of historians and archaeologists; kotun 'city' in the Dagur language in general. This appellative of the Dagur language is an appellative of common Mongolian origin, having parallels in all Mongolian languages: hot 'I 1) city. 2) khoton, a group of yurts. 3) camp; cattle yard’ /Mong./; khoto I ‘city’ /Bur./. Secondly, both documents of archival origin, indicating various kinds of morphological rearrangements of oikonyms, and information representing the ethnocultural specificity and local history value of toponyms introduced into scientific circulation. Thirdly, the results of the description of a number of oikonyms, nominatively related in lexico-semantic terms to the Dagur-language names of fortified fortifications or "towns", reveal the ambiguity of understanding the so-called a "nomadic civilization" that had both cities and fortifications in its centuries-old practice.
