售罄 (shòu qìng) literally combines 售 (shòu), meaning 'to sell', and 罄 (qìng), meaning 'to exhaust' or 'to run out completely'. Together, they form a compound adjective meaning 'sold out' — indicating that every unit of a product or service is no longer available for purchase. It’s commonly used in commercial contexts such as retail, ticketing, e-commerce, and event management.

This word carries a formal, concise tone and appears frequently in announcements, online product pages, and news reports. Unlike the more colloquial 没了 (méi le) or 卖光了 (mài guāng le), 售罄 sounds professional and slightly literary — it’s often seen on official notices or status labels ('库存售罄' / 'stock sold out'). While it can describe physical goods (e.g., concert tickets, limited-edition sneakers), it’s rarely used for abstract or non-commercial concepts like time or emotions.
