Question Tags Questions
Question tags and yes-no questions are both types of interrogative sentences, but they serve different purposes and have different structures.
Question tags are used to confirm or seek agreement with a statement that has been made. They are usually added at the end of a statement and consist of an auxiliary verb and a pronoun. The pronoun in the question tag is usually the opposite of the subject in the statement. For example, in the statement "You like coffee, don't you?", the question tag "don't you?" seeks confirmation or agreement from the listener.
Yes-no questions, on the other hand, are used to ask for information or clarification. They are formed by inverting the subject and auxiliary verb of a statement. Yes-no questions typically begin with an auxiliary verb or the verb "to be" followed by the subject and the main verb. For example, in the statement "She is going to the party," the yes-no question "Is she going to the party?" asks for confirmation or information about the subject's action.
In summary, question tags are used to seek confirmation or agreement with a statement, while yes-no questions are used to ask for information or clarification.
