Linguistic combinatory processes “assimilation” and “borrowing” as a basis for the development of modern english terminology

The article is devoted to the study and scientific description of the semantic features of foreign terms of the English-language origin in the modern Russian language. There are three main groups in terms of the degree of semantic development of borrowed lexemes that have entered modern Russian in the contemporary times. By the material of publicistic literature, Internet publications, explanatory, foreign and etymological dictionaries, an attempt is made to analyze the mechanisms of reception and adaptation of the English-language terminology. The semantic changes of Anglicisms leasing, detector, monitoring are investigated.
