The language is entering the era of the information society and is undergoing changes associated with borrowing words from the dominant language. With the development of social, political, economic and cultural conditions with other societies, there is a “mixing of languages” or “language contact”. This process affects the structure or vocabulary of one of the languages. Since contact occurs through the social and speech interaction of native speakers, the result is either minor changes in vocabulary or significant structural changes at all language levels. In the vocabulary of any language, there are many borrowed words, which are very diverse both in their composition and in the degree of penetration into the language they are borrowed from. Of all the units of a language – phonetic, grammatical, and lexical-words are usually the most easily borrowed due to their General mobility. However, in the vocabulary of any language there are, as we already know, different “layers”, different categories of words that are borrowed in different ways. The problem of borrowing in vocabulary has both a general and a particular aspect, due to the peculiarity of the relationship between different languages.

Covid-19 has changed tourism significantly. Numerous research shows how various factors will affect travel after COVID-19. No doubt that tourism has become a major global industry with an annual average growth rate of 4-5%. It also creates 8% of the global GDP and 10% of employment. Yet it is also very vulnerable to crises of different origin such as natural disasters, epidemics, economic crises, political crises, terror, etc. Because tourism product (e.g. hotel beds, airline seats, restaurant tables, guide services) is perishable, unlike physical goods, they cannot be stored for future use. Past crises with few exceptions (e.g. 2008 Financial Crisis, 2014 Financial Crisis, the terroristic attack of airplane in Cairo 31st of October, 2015) had regional impacts and their global impact on tourism volume was limited. Yet, taking into account the speed and impact, Covid-19 is the most serious crises tourism industry has ever faced. This crisis is estimated to have a seven time larger impact on tourism than the 2008 Financial Crises. The effects of Covid-19 are expected to extend for two years and result in a decrease of 39-50% in global tourism volume. Tourism industry is expected to recover to 2019 pre-crises levels not before 2023.

On the basis of data provided by the Department of architecture and urban planning of the city of Rostov-on-don, the problem of the choice of the territory for complex development that will be in priority for the construction of high-rise and unique buildings is solved. The objective of the study was the development of a methodology for selection of the area and the implementation of the proposed method on the example of evaluation of four-territories complex development. The developed method along with standard indicators of complex evaluation considers additional indicators that assess the territory from the position of high-rise unique building. The final result of the study is the rankings of the functional priority areas that takes into account the construction of both residential and public and business objects of unique high-rise construction. The use of the developed methodology will allow investors and customers to assess the investment attractiveness of the future unique construction project on the proposed site.
