Etymology
腔 combines the flesh radical ⺼ with 空 (empty, hollow), suggesting an empty space within the body. The component 空 likely contributes both sound and the idea of hollowness.
Meaning mnemonic
The flesh radical ⺼ on the left represents the body, and 空 on the right means empty. Picture an empty hollow space inside the body: a body cavity.
Reading mnemonic
For コウ, imagine a hollow body cavity echoing with a deep 'koh' sound: koh -> コウ, like the sound resonating in an empty space.
