Episode 190 Couch Potato or Sofa Potato? Is there a right answer?

This week's episode comes from a question from a student who heard this phrase from a colleague and wondered what was wrong. They asked me what was the difference between a 'sofa potato' and a 'couch potato'. It's a good question, so I thought we'd look more deeply at these tricky idiomatic expressions. We'll talk a bit about what an idiomatic expression is, what it does, and why it's so tricky and then we'll have a look at some similar idiomatic expressions that have two words that together make an entirely different meaning to what the words mean separately. I hope you find this useful. I have lots of questions for you. I find idioms very interesting because most languages have them, and often we have a similar idea, but we use different words to describe them. So tell me in the comments what the translations of your similar idioms are and where you're from.
