Yesno

In linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, is a closed-ended question whose expected answer is one of two choices, one that provides either an affirmative or negative answer to the question. Typically, the choices are either "yes" or "no" in English. Yes–no questions present an exclusive disjunction, namely a pair of alternatives of which only one is a felicitous answer. In English, such questions can be formed in both positive and negative forms:positive yes/no question: "Will you be here tomorrow?" negative yes/no question: "Won't you be here tomorrow?"
