garrulous, disturbed, restless
嘵 centers on a state of noisy, unsettled agitation: being garrulous (talking excessively) or disturbed and restless. The common thread is a lack of calm quiet.
嘵 combines 口 (mouth) with 堯, which likely contributes the sound and may suggest a high or excessive quality. The character expresses excessive talking or a disturbed state through the mouth.
A mouth (口) beside 堯, which looks like piled-up earth and legs, suggests a mouth that keeps piling on words without rest — garrulous and restless.
For キョウ, imagine a person so garrulous they keep saying 'kyou, kyou, kyou' (like 'today, today, today') without stopping, disturbing everyone around them.
