chronic illness, getting crippled
癈 centers on a lasting, debilitating condition: a chronic illness that progressively weakens or cripples a person.
癈 combines 疒 (sickness) with 發, which likely contributes the sound ハイ and the idea of something emerging or developing, suggesting a sickness that develops into a chronic, crippling condition.
The sickness enclosure 疒 wraps around 發, which resembles something shooting out or developing. Picture a sickness that slowly develops and shoots pain through the body, leaving the person crippled over time.
For ハイ, imagine a person with a chronic illness sighing 'hai...' (a weary sigh) as they struggle with their condition: the sigh 'hai' cues ハイ.
