fear, agitation, confusion, hurry
遽 centers on a sudden, overwhelming state of mind: fear, agitation, or confusion that makes one hurry or act hastily.
遽 combines 辶 (movement) with 豦, which likely contributes both sound and the idea of a wild boar's sudden, agitated charge, giving the sense of hurried, fearful action.
The movement radical 辶 suggests rushing, while the inner 豦 looks like a startled animal. Imagine a wild boar suddenly bursting through the brush, causing fear and confusion as everyone hurries away.
For キョ, picture a startled person letting out a sharp 'kyo!' sound as they jump back in fear and hurry away: kyo -> キョ.
