This document discusses English as a global lingua franca and issues related to teaching English. It begins by defining a lingua franca as a language used for communication between speakers of different first languages. English has become the dominant global lingua franca due to Britain's former colonial power. While a global language provides advantages of wider communication, it can also perpetuate power imbalances. The document then discusses debates around which variety of English to teach, noting arguments for both teaching standardized English as well as recognizing World Englishes. It also considers teaching English as a lingua franca without focusing on native-speaker norms. Finally, the document examines debates around defining native English speakers and their role as teachers.
