This article examines the principles of language structure in Uzbekistan and Tajikistan and examines the influence of foreign languages, especially English and Russian, on the development of these languages. The mechanisms of borrowing, as well as lexical, syntactic and semantic changes that occur as a result of interaction with the English language are discussed. The article also focuses on the importance of maintaining linguistic identity in the context of globalization and suggests strategies to improve and enrich the Uzbek and Tajik languages ​​through the integration of English vocabulary and cultural values. By analyzing current trends, the authors aim to offer recommendations for further research in the field of linguistics and linguistics. Aspects of vocabulary enrichment, syntactic and semantic changes, as well as the potential for multilingualism and borrowings are highlighted. Strategies that can accelerate the process of adaptation and improvement of local languages ​​are also discussed, including the integration of foreign languages ​​into educational systems, the creation of platforms for knowledge sharing, and the support of cultural initiatives. The article highlights the importance of preserving linguistic identity in the context of globalization and the necessary attention to different aspects of linguistic change.

The article examines the importance of linguistics in contemporary society, focusing on several key aspects. Globalization and the increase in multilingualism increase the importance of studying linguistic change and its impact on cultural identities. The rapid development of technologies, including the Internet and social media, gives rise to new forms of communication and linguistic innovation. Research in the fields of neurolinguistics, sociolinguistics, and cognitive linguistics helps to gain a deeper understanding of the relationship between language and thought. Linguistics  is also important in education, social justice, and identity studies. It is concluded that these disciplines will continue to be relevant and important for understanding communication and the cultural characteristics of humanity.
