ОБЩЕЕ ЯЗЫКОЗНАНИЕ INTERDISCOURSE COMMUNICATION: THE LINGUISTIC RELATIVITY PERSPECTIVE Gunta Rozina, Indra Karapetjana Department of English Studies University of Latvia, Riga 19 Raina Blvd., Riga LV 1586, Latvia The paper concerns the phenomenon of interdiscourse communication and views it from the perspective of Linguistic Relativity Theory. <...> The goal of the paper is to analyse the linguistic behaviour of non-native language users, who apply the English language for instrumental purposes in interaction, which establishes in multinational discourse among interactants having different cultural backgrounds. <...> The paper reports on some of the research results that were acquired in the period from 2011 to 2013 during the ERASMUS Intensive Programme project Cross-Cultural Competence and Interaction. <...> The focus of the study was on analysing the linguistic and pragmatic strategies prioritised by the tertiary level Latvian and Lithuanian interactants for whom the English language served as the instrument of communication in the multinational discourse community, which was constructed of students from Latvia, Lithuania and Turkey. <...> The research findings reveal that non-native language users having the cultural background of the Baltic States construct their own mode of interaction related to the linguistic behaviour, in which the interactants apply clarity and directness as the prevailing strategies of interdiscourse communication. <...> It was the German philosopher and ethnographer Alexander von Humbolt (1769—1859) who stated that a language cannot be taught; one can only create conditions for the language acquisition and use to take place. <...> From the present time perspective, we have to admit that a language is an expression of both culture and individuality of the language user. <...> It is the language user who perceives the world through the language and who sees culture as a classified and comprehensive means of providing information. <...> Language is viewed as a linguistic, pragmatic and social practice. <...> Thus, linguistic behaviour and cultural awareness of the language users become one of the core issues that affect language application in situational, cultural and interpersonal contexts that manifest the interactants’ linguistic and pragmatic competences this way. 59 Вестник РУДН, серия Лингвистика, 2013, № 4 To characterise current interdiscourse communication, it should be noted that appropriate and relevant language application is not viewed only as a cognitive process any more. <...> Interdiscourse communication <...>
