You will hear a lot of people saying, “You live in England, right?”
WRONG! Whilst this is understandable it is not good English; we need a tag… “You live in England, don’t you?”
Tag Questions are difficult, as they change in every tense. If the main part of the sentence is positive, then the tag question will be negative, and vice versa. Almost all verbs have the same negative formation, but the verbs to be (+ to be able and to be allowed) and can are exceptions.
Watch out with the first person ( I ) and the verb to be! (I am helpful, aren’t I?)
