About
The character "蹶" is a phono-semantic compound composed of the radical "足" indicating foot-related movement and the component "厥" which provides phonetic guidance and contributes a semantic sense of collapse. Its earliest meanings involved physical stumbling or falling, particularly in reference to horses or people losing their footing. Over centuries, the term acquired extended metaphorical applications, such as denoting defeat or failure in endeavors, exemplified in the idiom "一蹶不振" where it conveys a lasting setback. The character's structure has remained unchanged, with "足" consistently linking it to actions of the feet and "厥" reinforcing connotations of a fall or decline.
