Research on the incorporation of the emerging English as a lingua franca (ELF) paradigm into English language teaching has flourished in recent years, foregrounding the necessity of translanguaging practices. However, despite the growing awareness of ELF, teachers still struggle to determine whether and how to adhere to the emerging paradigm. In particular, the authenticity of ELF teaching methods in the English language classroom has not been sufficiently addressed, and therefore, needs to be revamped. The aim of this paper is twofold. On the one hand, it explores the aspect of teachers’ ELF awareness in English teaching practices as well as the importance of incorporating authentic ELF materials into the classroom to help learners become ELF-aware and, consequently, competent intercultural speakers. On the other hand, it helps English language teachers, specifically those who have no or marginal exposure to ELF to reflect on the subject they teach, challenging the dominant World Englishes paradigm.
