Answer:
A tag question is a construction in which an interrogative element is added to a declarative or an imperative clause. The resulting speech act comprises an assertion paired with a request for confirmation. For instance, the English tag question "You're John, aren't you?
a short phrase such as "isn't it" or "don't you" that is added to the end of a sentence to check information or to ask if someone agrees with you: In the sentence "It's hot, isn't it?", "isn't it" is a question tag.

Below are a few examples.
- You came by train, didn't you?
