This study examines the phonological, lexical, and syntactic traits of English as a lingua franca (ELF), emphasizing how these traits manifest in international communication settings. It looks into how ELF speakers adjust to differences, negotiate meaning, and use mutually intelligibility techniques. The study demonstrates the flexibility and adaptability of ELF, emphasizing both its influence on linguistic norms and identities as well as its function as a medium for cross- cultural communication. The analysis underlines the need for a nuanced understanding of linguistic diversity in globalized settings and highlights the dynamic nature of ELF, which is shaped by multilingual interactions and cultural influences.
