The article is devoted to the theoretical justification of a linguacultural competence of future specialists as a key competence in current educational environment. The author determined the essence of the key concept of “linguocultural competence” as a key competence, which involves knowledge of the historical, cultural, regional geographic features, ethnocultural background of the country, expressing the tolerance, respect and understanding of the sociocultural characteristics of representatives of other cultures; identification of social responsibility regarding their own behavior as a citizen of the Ukrainian state. It has been revealed that in the conditions of intercultural communication, future specialists should not only interpret another culture, but also be aware of themselves as part of Ukrainian culture, be true representatives of their native culture. The basis of worldview and understanding of each nation is its own system of subject values and social stereotypes. It has been studied that norms based on a moral code contribute to the formation of cultural values in the form of generally accepted, standard patterns of human behavior and actions in a particular society, that is, they are a kind of standards of expected behavior in typified situations and, subject to acceptance by the individual, is its regulator behavior. In fact, it is impossible to see the culture itself, its manifestations are noticeable only in behavior, actions, judgments, reactions or in a clothing style. It is proved that the linguacultural competence of future specialists as key in the current educational sphere involves: knowledge of historical and cultural material (historical and cultural heritage, ethnocultural background) knowledge of lexical units with national and cultural semantics; knowledge of the features of writing; ability to navigate in a multicultural world, while showing tolerance and respect for representatives of other cultures; knowledge of behavioral interlocutors of other cultures and the ability to adequately assess behavior, put oneself in the place of others; knowledge of the linguistic features of another sociocultural environment and the ability to build relationships with people of other sociocultural spheres and to exercise diplomacy in order to maintain a dialogue of cultures.
