This question <https://english.stackexchange.com/questions/111070/are-constructions-like-thats-me-out-then-primarily-british-rather-than-ameri> is more about "that's" This question's answers <https://english.stackexchange.com/questions/189416/when-a-person-replies-with-a-sentence-starting-with-then-than-should-it-be> are very close, but the "then" is almost a conjunction there, not an offhand interjection Related, the "yes", "right", "no", "ja", and "okay" in - The one around the corner, yes? - And we'll meet again on Tuesday, right? - We don't want to be too hasty, no? - We've covered this topic before, ja? - So we will only stay a little while, okay? do not read like classic question-tags as they do not use a form of "to be". They might confirmatory or leading This is not in the form of a question, but it feels the same to me - We'll see you at the party, then Even when the sentence has a question mark, sometimes it's not really asking (allofunctional implicature); I just want to know what that last word is called and if it should ever be "than" Cheers
