sound of spitting
囨 represents the sound of spitting. It is a rare character with no broader conceptual center beyond that specific onomatopoeic meaning.
囨 is a rare character formed by the enclosure 囗 and the phonetic 不, likely created to represent the sound of spitting. The exact historical development is uncertain.
Inside the enclosure 囗, the shape 不 looks like someone spitting out a negative response. Picture a mouth (囗) expelling a sharp 'puh' sound (不) to show disgust.
For ヘン, imagine the sound of spitting as a sharp 'hen!'—like a quick, dismissive noise. The spitting sound itself cues ヘン.
