David Crystal is nothing short of a national treasure and I can't believe I'm talking to him on my podcast today. He's kind of a big deal for anyone interested in language and language teaching so without further introduction here is my conversation about language with Professor David Crystal. So hello, David Crystal. Well, good day to you. First of all, I would just like to say that I'm delighted to have you on my podcast because there are so many things that I could ask you. We're going to have a good time. Okay, let's talk, let's have a quick conversation, how do you think? That's what we're going to do. Yes.
