This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
趬 combines the movement radical 走 with 堯, which likely contributes a phonetic element. The exact historical development is uncertain, and the character is rare in modern Japanese.
The running radical 走 suggests movement, but the overall meaning is unclear. Imagine a swift, light-footed motion, as the kun reading みがるい hints at nimbleness.
For キョウ, picture a nimble athlete in Kyoto (キョウ) sprinting lightly: Kyoto -> キョウ, matching the light-footed feel of みがるい.
