I looked over our episode today and I think there's a mistake.

Well, it says we're supposed to be talking about expletives, but I don't think that's appropriate.

Yes, and grammar expletives are words that have grammatical purpose but do not carry meaning.

There is a good way to explain the subject.

 But the individual word there and expletive doesn't have a It is serving a grammatical purpose.
