The effects of globalization and increasing international interaction pose a challenge to modern societies in overcoming language barriers in the context of intercultural communication and national identity formation. In a world where different cultures, languages and values meet, there is a need for tools and strategies that promote mutual understanding, tolerance and the preservation of cultural characteristics. International communication is an important part of the modern world, where people from different cultures and languages communicate and exchange information. However, in the process of international communication, language and cultural barriers often arise, which can lead to misunderstandings and misperception of information. One of the main factors leading to language barriers is the difference in languages and thought structures. Each language has its own unique grammatical and lexical features that can be difficult for other cultures to understand and use. In addition, different cultures may have different ways of perceiving information and a different set of norms and values that influence the perception and interpretation of messages. This research article aims to explore the role of overcoming language barriers in the context of intercultural communication and its impact on national identity formation. It focuses on the analysis of various aspects, such as foreign language learning, cultural education, empathy and the use of auxiliary communication tools, which contribute to overcoming language barriers and improving interethnic interaction. This article reviews the literature covering the relevant aspects of intercultural communication, the impact of language barriers on it and their relationship with the formation of national identity; strategies for overcoming language barriers, such as learning foreign languages, cultural education and the use of auxiliary communication tools, are considered.
