Why should you care? Because, as you already know (don’ t you?) David Crystal is the absolute guru of English language study. He’s a proper serious linguist yet has done more than anyone else to popularise academically respectable ideas about language. If you want to have just one book about language on your shelves, make it David Crystal’s Cambridge Encyclopedia of the English Language.
I took some sixth-form students to a study day in Leeds a few years back and when Crystal came on he was greeted like a rock star. Honestly. I’m not being ironic or hyperbolic here.
And now he has a blog, so you can read what’s on his mind just now. You can leave comments and maybe he’ll answer them. You can read his advice to a sixth-form student about doing research (it’s one of his first posts).
So what are you waiting for? get along to david-crystal.blogspot.com now!
