Within the article some aspects of manifestation of linguistic, terminological, communicative-pragmatic, textual, discursive competencies of the psycholinguistic profile of specialists in economic sphere are characterized. The influence of personal traits of an preceptor-economist on the formation of linguistic personality of an emerging economist is determined. Scientific works are analyzed, which allow to define a linguistic personality as a personality expressed in language and through language; as a person who is a native speaker and communicator, a holder of communicative competence. There are three levels of language proficiency: verbal-semantic, linguocognitive, pragmatic, the boundaries between which are quite fragile, vague; they also determine the stages of formation of linguistic personality. The requirements to the economic competence of a specialist are determined, which ensure the appropriate level of language proficiency, as lexical units of the language system occupy a priority place in professional speech of economic specialists: economic terminology of narrow and wide use, professionalisms, socially marked vocabulary, etc. The intralinguistic reasons for the dynamic penetration of lexical borrowings into professional speech of modern economists in connection with the nominative necessity are analyzed. With all due respect to foreign language culture, economic experts themselves are increasingly advocating the ecology of professional language, trying to use at least sporadically synonymous Ukrainian equivalents to the borrowings. Important communicative features of professional speech have been determined: content, accuracy, consistency, concise presentation of thoughts, provability, correctness and appropriateness of the terms use, information saturation, purity of speech, expressiveness of diction, melodiousness. Thus, indicators of general cultural, linguistic, terminological competence of an economist are deep knowledge of features of economic terminology, theory and practice of speech influence, attentive attitude to specific vocabulary and professional terms. Formation of the psycholinguistic profile of the personality of a novice economist depends on the fundamental language training, example and influence of the personal traits of the preceptoreconomist. The language development of a modern students of economic specialties largely depends on the state support, but above all on their own desire for self-development and selfrealization.
