tag question

  Robert_Haigh  —  Grammar Tips
A brief question which is tacked on to the end of a statement. English uses two different kinds of tag question, both of somewhat complex formation. Consider the statement Astrid is Norwegian.

One kind of tag question extends this statement so as to ask for explicit confirmation: Astrid is Norwegian, isn't she?

The other kind of tag usually forms only a rhetorical question not requiring a response: Astrid is Norwegian, is she?
