crouch, cower
踞 centers on lowering the body into a defensive or resting posture: crouching down or cowering in fear.
踞 combines 足 (foot/leg) with 居, which likely contributes both sound and the idea of being settled or seated, suggesting a posture where the legs are bent close to the body.
The left side 足 (foot/leg) and right side 居 (reside) together suggest legs folded under the body while staying in one spot, like crouching or cowering.
For キョ, imagine a person crouching in a narrow kyo (invented sound) space, like a small closet: kyo -> キョ, and the cramped posture forces them to crouch.
