First question. Which of these "tag question" variations is most correct?
- You're going, right John?
- You're going, right, John?
- You're going. Right, John?
(1) looks best, imo. (2) seems more proper, though. (3) seems way too emphatic.
Second question. What is the technical/grammatical name for the person being addressed in these sentences? "John" is a proper name, obviously, but how do you describe its function within the sentences above? "Target"? "Object"? "Addressee"? I assume there's a more technical term for it.
