The article considers the importance and necessity of formation and use of Ukrainian-language specialized thesaurus resources in various fields, which will act as an effective tool for professional speech training of foreign students in higher medical institutions not only in basic higher education, but also in new continuing education, education (for life). The urgency of accelerating work on the creation of national Ukrainian-language thesauri of both general and professional orientations, which is due to further integration processes, when domestic free economic zones are included in the training of specialists for the global labor market. Therefore, it is necessary to create a national Ukrainian-language thesaurus, which must be adapted and / or identical to global thesauri (today English-language thesauri are quite common for the world labor market and the world educational space). There is a further increase in intersectoral relationships that increase the lexical and semantic load on existing dictionaries, words, and terms, as well as the growing number of new words, terms and definitions in terms of entering the digital (cybernetic) component in all areas. In addition, the number of bilingual foreign students is growing every year, who, in addition to the national language, also speak English, which increases the level of their competencies. That is why it is necessary to compile English-Ukrainian explanatory dictionaries of professional terms in various fields, which on the one hand will improve the adaptation of foreign students to Ukrainian-language vocational education, and on the other hand, will promote the formation of Ukrainian-language professional thesaurus in the context of world thesauri. Concerning the medical field, first of all it is necessary to take measures to ensure that the multilingual MeSH (Medical Subject Headings) thesaurus also becomes Ukrainian-speaking and has open access for the entire medical community (education, science, broadcasters, professionals) online. In addition, this resource can be taken as a basis, creating additional thesauri at the national level, where the rights to them will be for our country, which will allow free use of available resources. In addition, it is necessary to unite the efforts of domestic scientists (broadcasters, professionals) to create a Ukrainian thesaurus in professional areas of high quality and deep content.
