Abstract
The work is devoted to the description of the term “thesaurus” as a constituent of the category “language personality”. We present a brief overview of scientific information on the formation of the meanings and status of these terms in modern linguistics. The idea is substantiated that in the practice of society’s life there is a desire among students to identify, clarify and understand a huge number of terms related to the modern realities of life (globalization, integration, informatization, westernization, etc.). We emphasize that modern terminological dictionaries, especially special dictionaries - thesauruses, are becoming particularly relevant in the field of specialists' professional training. We emphasize the need to improve the training quality of future specialists based on the formation and improvement of their thesaurus as one of the important language personality components.
