I loved this week's episode of The Word Nerds. We seem to have a real problem with vocabulary in class, especially when it comes to seeing prefixes and suffixes. This episode seemed pretty understandable. I am thinking about playing it for class and then just a bit of discussion.
I love the topic of registers, it's a way of talking about language that implies that casual speech isn't wrong, it's just not always appropriate. I wonder how much they will grasp the idea of code switching.
Even if it bombs in class, you can listen and discuss.
