The last episode of this five-part documentary (hosted by Stephen Fry)
about language aired last night. It touches upon a lot of very
interesting aspects of language like its origins, growth, accents,
multilingualism, profanity, written language, storytelling etc. I
would strongly recommend it to those who're curious to know more about
the evolution of language.
