A lingua franca is a language that serves as a common medium of communication among groups without a shared native language, often arising from trade, colonization, or diplomacy. Historically, languages such as Latin, Arabic, and Chinese acted as links between cultures, while contemporary examples include English and French. Scholars like E. W.
Burgess emphasized English’s function as a Pacific lingua franca, fostering cross-cultural exchange, while Sir Richard Francis Burton pointed out the flexibility of pidgin English in promoting understanding. Marie Lebert examined the shifting nature of global multilingualism, casting doubt on English’s supremacy. These viewpoints highlight how lingua francas embody both practical need and the adaptability of linguistic identity across different times and places.
