Rules for Comma Usage. Tip #7: Comma with a Question Tag
A question tag
is a short phrase or even a single word that is added to the end of a statement
to turn it into a question. Writers often use question tags to encourage
readers to agree with them. A question tag should be preceded
by a comma.
Example: You didn’t
actually write a 600-page vampire romance novel, did you? I know, right?- Ты ведь
не писал 600-страничный любовный роман о вампирах, не так ли? Я знаю, верно?
