The Chinese word **问答 (wèndá)**, meaning "question and answer" or "Q&A," is a **coordinating compound** formed by combining two independent, semantically related characters: **问 (wèn)**, which means "to ask," and **答 (dá)**, which means "to answer" or "to reply." In this construction, the two morphemes are of equal grammatical status and are juxtaposed to create a new, cohesive concept that encompasses the entire interactive process or format of an exchange involving both actions, effectively meaning "the act of asking and answering."
