Language, Identity, and Power on Social Media: A Sociolinguistic Study of Digital Communities

This paper examines how language practices on social media construct, negotiate, and contest identity and power in digital communities. Drawing on sociolinguistic theories of discourse, identity performance, code-switching, and linguistic ideology, the study analyzes how users on platforms such as Instagram, X (formerly Twitter), YouTube, and WhatsApp strategically deploy linguistic resources to signal belonging, assert authority, resist marginalization, and shape collective narratives. The paper argues that digital communication is not merely a reflection of offline sociolinguistic patterns but an intensified, accelerated, and algorithmically mediated arena where linguistic choices carry heightened social consequences. Through examples from Indian multilingual contexts, global youth culture, and influencer discourse, the study demonstrates how digital language practices reinforce and disrupt hierarchies of class, caste, gender, and ethnicity. The findings highlight the need for a critical sociolinguistic understanding of digital spaces, where language becomes a tool of visibility, virality, and symbolic capital.
