The American teen polyglot who speaks 23 languages

Timothy Doner, 16, from New York City, has taught himself to speak 23 languages from Hebrew and Arabic to Swahili and Chinese. The teenager said: "Some of the languages that I speak, or I've studied, are French, Latin, ancient Greek, Mandarin, Chinese, Japanese, Hebrew, Arabic, Farsi, Pashto, Hindi, Indonesian, Wolof, Hausa, Swahili, isiXhosa, Ojibwe, Dutch, Italian."

Timothy first learnt Hebrew, before moving onto Arabic. The polyglot now practices languages at restaurants and meet-ups throughout New York, speaking Arabic in Astoria, Queens to Mandarin in New York City's Chinatown neighbourhood. Report by Matt Blake.
