Why are Variation and English as a Lingua Franca Important Tools within the EFL Class?

This article focuses on the importance of variation and English as a Lingua Franca (ELF) within the EFL class, as this language shows a plurality of native and nonnative varieties. Most of the interactions take place between speakers of different L1, where ELF works as a shared code. Concerning variation, this study highlights how its use allows learners to mirror the cultural identity of their interlocutors by developing extremely effective mutual understanding. Finally, examples of experience-based activities show how the use of communication strategies elicits important life skills, whose development is strongly recommended by Agenda 2030.
