Abstract
The transformation of the tourism industry is accompanied by changes in the organization of travel, the production of tourism services, and interactions among market participants. These processes are reflected in professional terminology, much of which is developed and disseminated through English. This study aims to systematize English-language terminological units in contemporary tourism and explain their relationship with key areas of industry transformation. It adopts a theoretical and analytical design combining conceptual synthesis of the literature, terminological comparison, and thematic classification. The material comprises scholarly publications, international tourism documents, and a purposively compiled analytical list of 90 English terminological units. The list is used to systematize concepts and is not treated as a representative corpus of Russian-language usage. Direct borrowing, calquing, descriptive translation, and the use of international abbreviations are distinguished. Six interrelated areas of terminological renewal are identified: digitalization, changing tourist behavior, diversification of accommodation and services, sustainable development, marketing transformation, and the development of platform business models. The study proposes a classification linking terms to the industry changes they denote and a conceptual model connecting transformative factors, new practices, their naming, and cross-linguistic adaptation. The diagnostic value of terminology depends on the specificity of the practice denoted rather than the foreign form of the word. The existence of a term does not, by itself, establish the extent to which the corresponding phenomenon has spread. The theoretical contribution lies in integrating industry and terminological analysis. Practical applications include professional education, multilingual glossaries, tourism product development, and communication materials.
