This article analyzes the development of English in the epoch of globalization, the evolutionary changes causing the appearance of new variants of English, and the functions of English in social life. Moreover, it deals with the rapid spread of English, which is believed to be one of the main tendencies of globalization This study offers an insight into the problem of English language variation. We also discuss the criteria to define both local variants and Global English and perspectives of their development. Globalization has led to the widespread use of English as the language of international communication (Lingua Franca), which facilitates communication between people from different cultures and countries. The dominance of English is due to the influence of English-speaking economies, technologies, and its role in education and science, where English has become the primary language for academic publications and research. This promotes cultural exchange, but also raises concerns about the possible displacement of local languages and cultures. Some researchers, in particular R. Phillipson, emphasize the risk of linguistic imperialism, when English reinforces the dominance of Western ideas and values. However, the spread of English as a Lingua Franca leads to its localization, producing different variants that reflect local cultures and needs. This adaptability allows English to integrate into different linguistic environments, although it creates new linguistic norms that differ from those of native speakers.
