I'm Kavi and I'm Rossiya copy.

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

What is it?

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

No, Lucy, it it's not expletives, as in offensive words, but expletives as in grammar.

Seriously?

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

There is a good way to explain the subject.

I just know it, but I don't think I know much about expletives.

Well, you actually just gave a really good example.

You use what is called in existentially their sentence.

What is that?

Let me explain by using a shorter sentence.

There are mice in the house there, and expletive is the grammatical subject.

Mice is the logical subject and in the house is an adverb Beall.

OK, but why would I use on expletive if it has no meaning?

Phrases such as there is or there are point to the existence of something they have meaning.

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