Meanings
There are two key rules for forming question tags.
- Rule 1: Use the same auxiliary verb.
If there is no auxiliary, use do/does/did.
He is smart, isn’t he?
You like pizza, don’t you? - Rule 2: Use a subject pronoun.
Never use a name or noun in the tag.
Maria is here, isn’t she? (NOTisn’t Maria?)
