Hi,
Welcome to the Forum.
I've got a question about tag questions.
A tag question is for ex. "You don't go home, do you ?" or "It is strange, isn't it ?"
How do you form a tag question if the subject is a pronoun like nobody or somebody ?
Nobody was expecting that, wasn't ______ ....? ...he ? it ?
First, a couple of comments.
1. Questions with negative words like nobody or nothing use positive tags.
2. Although words like nobody and somebody use a singular verb ('was' in your example), a plural pronoun is commonly used to refer to them.
Thus, what we say as a tag is this. Nobody was expecting that, were they?
Best wishes, Clive
