敏捷 (mǐn jié) is an adjective meaning 'agile' or 'nimble', describing someone or something that moves quickly and easily with precision. The first character 敏 (mǐn) means 'sensitive', 'quick to respond', or 'sharp', while 捷 (jié) means 'victorious', 'prompt', or 'swift'. Together, they emphasize both mental alertness and physical swiftness — not just speed, but coordinated, efficient movement. This word often appears in contexts involving animals, athletes, dancers, or skilled professionals like surgeons or programmers who act with rapid accuracy.

It's commonly used in descriptive writing, sports commentary, and biology texts — for example, highlighting how a cheetah’s reflexes and acceleration make it exceptionally agile. Unlike simple synonyms like 快 (kuài, 'fast'), 敏捷 implies control and adaptability during motion. It’s neutral in register and appropriate in both formal and informal settings, though rarely used for inanimate objects unless personified (e.g., a responsive robot).
