angry voice, gargle, throat
啌 centers on sounds and actions from the throat: an angry voice, gargling, or the throat itself. The meanings are connected by the throat as the source of vocal or guttural sounds.
啌 combines 口 (mouth) with 空, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound where 口 indicates a mouth-related action or sound.
The mouth 口 is open, and the right side 空 suggests emptiness or space. Picture an empty throat producing an angry voice or gargling sound.
For クウ, imagine an angry voice shouting 'COO!' from an empty throat: coo -> クウ, and the mouth 口 is wide open.
