The article considers the concept of Schastie/Bakht (Happiness) in the Russian and Uzbek linguistic cultures as one of the most important universal concepts with a national component. On the one hand, the study is conditioned by the interest of modern contrastive linguistics in the comparative research of concepts with a national component. On the other hand, it continues scientific works concerned with the concept of Schastie in the Russian linguistic culture and the concept of Bakht in the Uzbek linguistic culture. The novelty of this study is determined by the fact that this concept is compared for the first time using set phrases of two languages and based on an analytical review of the relevant sources. The article aims at determining common and different components for the Uzbek and Russian linguistic cultures with regard to the Happiness concept (according to the data obtained from the analysis of the above-mentioned material). The article presents the results of an analytical review of studies on the concept of Schastie in the Russian linguistic culture and the concept of Bakht in the Uzbek linguistic culture, as well as contrastive analysis of phraseological units related to the verbalization of these concepts. To analyze and compare idioms of two unrelated languages (Russian and Uzbek) and ways of verbalizing the concept, the authors used the method of linguistic and cultural description supplemented by the component analysis of lexemes and the comparative method. As a result, general and specific meanings for the words “schastie” and “bakht” were identified, as well as general and specific components of the Happiness concept.
