幸存 (xìng cún) literally combines 幸 (xìng), meaning 'fortunate' or 'lucky', and 存 (cún), meaning 'to exist' or 'to remain'. Together, they express the idea of 'remaining alive despite danger or hardship' — essentially 'to survive'. It emphasizes not just physical continuation but survival against odds, often implying luck, resilience, or exceptional circumstances.

This word is commonly used in contexts involving disasters, wars, accidents, illness, or ecological threats — for example, describing people who live through earthquakes or animals that endure habitat loss. While it can function as a verb (e.g., 他幸存下来), it also appears as a noun meaning 'survivor' (e.g., 地震幸存者). It carries a slightly formal or literary tone and is more frequent in written Chinese and news reporting than in casual speech.
