Routes of English: Freezing the River (Series 2, Programme 5)

English is constantly evolving, but some linguists have tried to 'freeze' it for good. We've been looking for a standard form of the language to adhere to for centuries. If there's one thing that's dominated our journey along the 'Routes of English', it is change. Melvyn investigates those who've tried to purify English and those who think it should be allowed to change.
