Language convergence: problems and solutions

The article results in the study of interlanguage contacts from the point of view of convergence and divergence processes. The basis of the research is the idea that the search for an etymon is preceded by the spatial-temporal stratification of language. After eliminating the possibility of infiltration of a foreign word, the transition is made to the search for an ethymon or internal form based on the language specified in the study, in this case, the Russian language.
