Polyglotism or polyglottism is the ability to master numerous languages. Multilingualism is a word with a similar meaning.

Richard Hudson, professor emeritus of linguistics at University College London, coined the term "hyperpolyglot" for a person who can speak six or more languages fluently.

Tim Doner is one of them. He has been teaching himself languages since he was 13. He now speaks nearly 20 languages! Find out how he does it by watching this video.
