The present research is aimed at studying the peculiarities of linguistic fixation of lexemes that verbalize the processes of mutual social adaptation of both Muslim immigrants and members of the British linguistic culture. The study of these questions allows us to present an image of the functioning of the processes in the language leading to a change in the semantics of the meaning of the relevant lexical units. The study of these processes is carried out on the analysis of anonymous letters, which have received considerable distribution in British society. These letters were distributed among the British with opposing goals, however, they are quite comparable for conducting this kind of research. As a result of studying the letters, there were identified and classified the lexical units, reflecting the necessary changes in the language. There were also revealed the changes in their semantics used in the axiological aspect, which allows assessing the degree and possible means of manipulating the opinion of the speakers. Thus, according to the results of the study, a number of lexemes were identified, characterized by an associative connection with the concept of Muslim immigrants. In the future, the results of this study will form the basis of the level model of language variability. With further deepening of the linguistic aspect of the study, it is possible to compile a database for studying manipulative strategies of regulating public opinion, and, as a result, changes at the verbal level
