TAG QUESTIONS The question tags are grammatical elements that are placed at the end of a sentence in the form of a short question and whose structure is opposed to the previous sentence. That is, if a sentence is affirmative, the accompanying question tag will be negative. The two main rules for forming question tags are that when a sentence is affirmative, the question is negative. Whereas when a sentence is negative, the question is positive. Structure: Affirmative sentence + negative question tag. Example: - You have been there, haven’t you? - He isn’t coming, is he?
