Question

tag the sentence it rained last night​

Answer 1

A question tag (also known as question tail) is a grammatical structure in which a declarative or an imperative statement is turned into an interrogative fragment (the "tag"). For example, in the sentence "You're John, aren't you?", the statement "You're John" is turned into a question by the tag "aren't you".

The term "question tag" is generally preferred by British grammarians, while their American counterparts prefer "tag question".
