Verb + 没 + Verb
The A-not-A question pattern is formed by placing a verb next to its negated form using 没, creating a yes-or-no question without a question particle. For example, 绑没绑 asks 'tied or not tied?' This structure is a core Chinese interrogative pattern and sounds more natural than adding 吗 in many conversational contexts.
