As university students mill around a bright and airy study hall in London, Eiad Zinah converses in his native Arabic with a female student from Germany.

It is the first time the pair have met for a language tuition session — and it is the Syrian refugee who is running the tutorial today, not the other way around.

"It's an amazing thing to be able to teach your language to other people because it will help them understand you more," the 30-year-old said after the language class organized by U.K. social enterprise Chatterbox at the University of London.
