Each language harbours historical, cultural, and social connotations, contributing to the layers of meaning within the narrative. Sociolinguistics studies how language and society interact, a topic covered in various literary works that examine dialects, the intricacies of communication, and the impact of language on individuals and groups. The study of language interacts with social factors, and sociolinguistics is the intersection of linguistics and sociology. Sociolinguistics, a multidisciplinary field, provides a rich framework for comprehending language dynamics in various social contexts. This study aims to investigate the representation of critical elements such as register, polyglossia, diglossia, code-switching, lexical borrowing, bilingualism, trilingualism, code-switching, and language planning in literary narratives. Through closely examining selected novels, this paper investigates how authors employ linguistic diversity as a narrative tool, mirroring societal norms, cultural identities, power dynamics, and intergroup communication. This research aims to contribute to a more in-depth understanding of language's role in shaping fictional worlds and reflecting real-world linguistic complexities by investigating the interplay between sociolinguistic concepts and literary expression.
