In the context of modern dialectology, we are observing the influence of a wide range of new theoretical approaches and technological innovations that are changing the traditional understanding and study of linguistic dialects. The development of digital technologies, especially in the areas of machine learning and big data processing, opens up new opportunities for analyzing language structures and the interaction between different dialects. This allows researchers to study and understand language differences in more detail and assess their impact on social and cultural processes. Modern dialectology also integrates cognitive and socio-linguistic approaches, enabling a more complete consideration of language as a complex system that reflects not only communicative but also cognitive and sociocultural aspects of human life. Expanding the availability of language data, in particular, through online platforms and social networks, opens up new perspectives for studying the dynamics of language dialects in the modern world. This requires us to rethink traditional approaches and adapt them to rapidly changing socio-cultural conditions. The research shows how the use of synchronic, diachronic and cognitive approaches enriches the understanding of linguistic variations. Particular attention is paid to the influence of cognitive linguistics on the perception of linguistic dialects, as well as the role of structural approaches and diasystems in understanding the interrelationships of different dialects. The conclusions of the academic paper emphasize the need to integrate various approaches in modern dialectology. The combination of traditional and innovative methods makes it possible to gain a deeper and more comprehensive understanding of language differences and their role in social and cultural processes. The success of modern dialectology lies not only in the preservation and use of traditional methods but also in the active incorporation of the latest research strategies that reflect the rapid changes in the linguistic and sociocultural landscape.
