fly
翃 centers on the action of flying, with its meaning rooted in the visual presence of wings.
翃 combines 厷 (possibly a phonetic component) with 羽 (wings), suggesting the idea of flying. The exact historical development is uncertain.
The right side 羽 shows a pair of wings, and the left side 厷 looks like a strong arm. Imagine a bird with powerful wings taking off: 翃 means fly.
For コウ, picture a bird flying high in the sky, soaring like a kite: kite -> コウ, and the wings 羽 carry it upward.
