The paper focuses on the methods of linguistic analysis in the sphere of teaching foreign languages as a form of shaping students' identity. By putting forward the hypothesis that proper language acquisition should be based on fundamental cultural values and their adequate linguistic interpretation, we propose the pragmatic and axiological linguistic modelling as an indispensable FLT tool, develop its methodology and prove its future validity on the material of FLT discourse. The research gives a step-by-step explanation of how to implement this modelling through discourse analysis, pragmatic-communicative analysis, functional and linguoaxiological analysis. This procedure foregrounds dominant axiological spheres through the process of constructing value-charged concepts of the professional FLT discourse. From the standpoint of generating FLT material, the method helps to reflect most important professional processes and purposefully form students' professional competences necessary in the sphere. © 2021 The AuthorsForeign language teaching; Language for specific purposes; Pragmatics; Axiology; Linguistic modelling; Target language; Professional identity; Professional values © 2021 The Authors
