Question tag

A question tag (/kwesʧən tæg/) is a tag clause added to the end of a statement to make a tag question.

A positive question tag consists of only an auxiliary verb and a pronoun. A negative question tag, in addition to having an auxiliary verb and a pronoun, has the word "not" for negation. They generally use the same auxiliary verb as the main statement. The polarity is generally reversed. There are two negative forms, a contracted form and an uncontracted form. It is the question tag that contains the grammatical marker that indicates the sentence is a question.
