This paper examines the formation of foreign-language discursive competence in conditions of the national-Russian bilingualism. Conceptual provisions of didactics, linguodidactics, ethnolinguodidactics and theoretical provisions on language and foreign-language education served a basis for the ethnolinguodidactic approach as a productive theoretical foundation for realization of multilingual education. The main attention is paid to interaction and interference of the contacting languages (Adyghe, Russian and English). In the context of this research, it seemed important to consider the issue of the correlation between language and culture which is brightly displayed in verbal communication.
