问答 (wèn dá) is a noun meaning 'Q&A' or 'question and answer'. It combines two characters: 问 (wèn), meaning 'to ask', and 答 (dá), meaning 'to answer'. Together, they form a compact, balanced compound that emphasizes the interactive, two-way nature of exchanging information. The term is commonly used in educational, professional, and digital contexts — such as classroom activities, conference sessions, help forums, or software interfaces.

Unlike standalone verbs like 问 or 答, 问答 functions almost exclusively as a noun or nominal phrase. It often appears with measure words like 一个 or 一场 (e.g., 一场问答), and may be modified by adjectives like 热烈的 ('lively') or 互动的 ('interactive'). While it can occasionally appear in verb-like constructions (e.g., 进行问答), it is never used as a verb on its own. It carries a neutral-to-formal register and is widely understood across age groups and regions.
