Tag questions are used to confirm if a statement is true or false. If the statement is positive, the tag question will be negative, such as "Esteban is really handsome, isn't he?". Conversely, if the statement is negative, the tag question will be positive, like "Esteban isn't handsome, is he?". Tag questions are helpful when a speaker wants confirmation of a detail and uses a short question at the end of a sentence to elicit agreement or disagreement from the listener.
