This paper is devoted to theoretical analysis of the problem of forming the linguistic personality of a student at technical universities. It is shown that this problem is relevant now. Linguistic, psychological and pedagogical aspects of linguistic personality formation are considered. It is proved that the linguistic aspect of the existence of a linguistic personality reveals a number of provisions that are fundamental to the methodology of teaching a foreign language, contributing to the development of more effective pedagogical learning models. The psychological aspect assumes that each student possesses peculiar communicative behavior manifested in specific situations of communication. This aspect also affects the conditions for the development of speech creativity in students including the creation of a creative environment for foreign language communication and learning and speech activities. The pedagogical aspect is aimed at developing in students a personal attitude to the content of language education, a readiness to carry out intercultural interaction and practical application of a foreign language. The article lists the basic principles of education aimed at the formation of the linguistic identity of technical university students. It is concluded that a methodologically well-organized foreign language environment contributes to the development of the student's linguistic personality in a non-linguistic university.
