comfortable, easy
摴 centers on a state of ease and comfort, suggesting something that feels relaxed or effortless.
摴 is a phono-semantic compound: the hand radical 扌 suggests an action, while 雩 likely contributes the sound. The exact historical development of the meaning 'comfortable, easy' is uncertain.
The hand 扌 beside 雩 looks like a hand resting under a rain-like canopy, a comfortable and easy position.
For チョ, imagine a comfortable chair: chair -> チョ, and your hand rests easily on its arm.
