'Jiàng luò sǎn' literally means 'descend-fall-umbrella' — a compound that vividly captures the function of a parachute: a device that slows descent (jiàng luò) during free fall, much like an umbrella opens to catch air. The character 降 means 'to descend' or 'to lower', 落 means 'to fall' or 'to land', and 伞 means 'umbrella'. Together, they form a transparent, descriptive noun widely used in aviation, military, sports, and emergency contexts.

This word is standard in both formal and informal Chinese, appearing in news reports about skydiving, aircraft emergencies, or space missions (e.g., spacecraft re-entry). Unlike English, where 'parachute' can also be a verb, 降落伞 is strictly a noun in Chinese; to express the action, you'd say '跳伞' (tiaǒ sǎn, 'to skydive') or '打开降落伞' (dǎkāi jiàngluòsǎn, 'to deploy the parachute'). It's rarely used metaphorically and carries no colloquial or slang connotations.
