拥挤 (yōng jǐ) is an adjective meaning 'crowded' or 'congested', describing a space where too many people or things are packed together, making movement difficult or uncomfortable. The character 拥 (yōng) means 'to crowd around' or 'to embrace', suggesting density and closeness; 挤 (jǐ) means 'to squeeze' or 'to press', emphasizing physical pressure and lack of space. Together, they form a vivid compound that conveys both the quantity and the resulting discomfort of overcrowding.

This word is commonly used to describe public spaces like subway cars, markets, tourist sites, or narrow streets—especially in urban settings. It carries a slightly negative connotation, implying inconvenience or stress rather than neutral density. Unlike more formal terms like 拥塞 (yōng sè), which often refers to traffic or systems, 拥挤 focuses on human-populated physical environments and is frequently heard in everyday speech and news reports about city life.
