Could you please remind me what term linguists and the grammar people use to call it when it's used as a subject pronoun, but the funky thing is that it doesn't really refer back to anything in particular like he, she or we usually do which do refer back to a person or an animal that they stand for.
In grammar-speak, when it is used like that they say that it has no antecedent. I think I knew the term, but I unfortunately forgot it. I did a Google search, but the only thing I could find was empty subject. But the truth is that I don't think that's what they actually use in linguistics. Would you please refresh my memory?
- It's quite cold today outside. So, I don't really wanna go out.
- Did I solve that math problem? Yes. Actually, it was very easy to get it cracked. There was really nothing to it!
- Don't mention it! It's nothing. I really like to help people who are in need.
