ELFA (English as a Lingua Franca in the Academia) investigates English as it is currently used by speakers with different mother tongues. It explores the practices, regularities, and patterns of English as a lingua franca (ELF) as it appears in natural use by ‘expert users’ in university settings. The project has compiled two large, electronically stored databases: ELFA of academic speech, and WrELFA of academic writing, freely available to the research community.
