The expansion of international contacts, the internationalization of all spheres of life due to the entry of the Republic of Uzbekistan into the world educational and socio-cultural space required the use of intercultural and linguodidactic aspects to the study of interference. For modern linguodidactics, the study of linguistic and cultural interference is also significant due to the intensification of professional activities of specialists of various profiles in close contact with foreign colleagues. In this article, interference is considered as a communicative hindrance due to the imposition of linguistic and cultural codes of the contacting languages.Also, the main postulate of the article is the fact that the growing interest of linguodidactics in the phenomenon of interference, which generates not only inter-linguistic (phonetic, lexico-grammatical, syntactic), but also discourse, socio-cultural interference in intercultural communication. As a result, interference is interpreted in a broad sense as a conflict interaction of cognitive-speech mechanisms, manifested in a secondary linguistic personality in deviations from the linguistic, discourse, sociocultural norms of one linguoculture under the influence of another.Language interference is actualized at all levels of the language system and is implemented in speech regardless of the speaker’s consciousness, therefore, until recently, interference research was mainly focused on studying its grammatical, lexical and phonetic aspects. However, interferences arising in intercultural communication often occur not only due to distortions of the grammatical, lexical or phonetic side of foreign language speech, although vocabulary is one of the most important forms of reflection of the ethno-cultural specifics of the worldview. Discourse and sociocultural phenomena that differ in ethnocultures often give rise to misunderstandings, hindrances, failures in intercultural communication, which can be overcome with a purposeful study of communicative behavior and background knowledge of representatives of a foreign cultural community.
