Features of phonetic adaptation of appellative vocabulary of Baltic-Finnish origin fin the context of transformational adaptation

This article is a continuation of the work on the results in the lexical sphere of contacts between the Baltic-Finnic population and adjacent dialects and languages. The work presents an analysis of the processes of mastering a number of units of Baltic-Finnic origin fin the etymological aspect against a broad background. This article is a reflection of some results from the development of this topic. When studying non-native flexion, its analysis encounters problems mediated by the oral form of existence of such data. In some cases, it is quite difficult to record with sufficient completeness all variants of a word that go back to a single etymon, both diachronic and territorial, which may in the future lead to not entirely correct conclusions regarding the search and development of their sources. The work used various types of sources both on the Finno-Ugric languages and on Russian dialects. Significant materials were obtained during field studies of the languages and dialects of the North-West. It is noted that borrowed and substrate Karelian-Veps data represent material that may have various possibilities for etymological analysis. Transformations often occur as a result of some infrequent phonetic changes and may also be a consequence of the search for the internal form of a word. This can occur both with borrowed and native data. In a number of cases, fin the course of etymological analysis of a significant number of dialect data of donor and recipient languages, it is possible to identify a kind of regular phonetic changes that help to verify etymological versions. The materials considered allow us to state various models of transformation of the original form of a word both fin the process of borrowing or assimilation of non-native data, which can be caused by various circumstances. Most often such processes occur on the basis of phonetic changes that accumulate during the existence of a lexeme fin a separate dialect system or during its territorial migration. Quite often transformational changes are due to the uniqueness of the local dialect phonetic system. Various kinds of transformations are especially characteristic of the vocabulary recorded fin folklore texts.
