This article explores the phenomenon of lexical borrowing and semantic shift within digital neologisms that have emerged at the intersection of Chinese and English languages. The rapid development of digital communication and social media platforms has facilitated a dynamic exchange of linguistic elements between cultures, giving rise to unique hybrid terms. The study analyzes the etymology, adaptation, and contextual meanings of selected Chinese-English neologisms used in online discourse. Special attention is given to how borrowed words undergo semantic transformation during cross-cultural integration, reflecting changing social values, technological innovation, and evolving communicative norms. Drawing on examples from platforms such as WeChat, TikTok (Douyin), and Xiaohongshu, this paper highlights how digital spaces function as laboratories for lexical experimentation and identity expression. The research contributes to the understanding of global linguistic convergence and the role of technology in shaping modern vocabulary.
