Although a significant number of practitioners are being progressively exposed to English as a lingua franca (ELF) research findings and developments, we still face the challenge of bringing ELF into the ELT classroom in a more systematic way and on a regular basis. It is a fact that once EFL learners move into contexts of use outside the classroom, they naturally become ELF users. To respond to this reality, ELF and EFL need to work together in such a way that the classroom reflects as much as possible what students have to deal with when using English to interact with interlocutors from different linguacultural backgrounds. Under a decolonizing perspective, the article seeks to discuss the feasibility and relevance of this integration, illustrating in practice how an ELF-EFL dialogue can emerge in ELT materials.
