‘跳伞’ literally means ‘jump + umbrella’ — a vivid, compound noun describing the sport or activity of descending from an aircraft using a parachute. The character 跳 (tiào) means ‘to jump’, emphasizing the action of leaping into the air; 伞 (sǎn) means ‘umbrella’, used here metaphorically to refer to the parachute that opens like an umbrella to slow the fall. Together, they form a single lexical unit meaning ‘parachuting’ or ‘skydiving’.

This term is used broadly in both recreational and military contexts. It commonly appears in news reports about extreme sports, training programs for pilots or special forces, and adventure tourism. While often associated with thrill-seeking, it also carries connotations of skill, preparation, and safety protocol — e.g., ‘跳伞训练’ (parachute training) or ‘跳伞教练’ (parachute instructor). It’s not used for casual or metaphorical ‘jumping’ — only when actual parachutes are involved.
