threaten
恊 centers on using force or pressure to intimidate: threatening someone to compel or coerce them.
恊 combines 忄 (heart/mind) with 劦 (a component associated with combined strength or force). The exact historical development is uncertain, but the structure suggests a mental or emotional state involving coercion or pressure.
The heart radical 忄 beside the forceful-looking 劦 (three 力 shapes) suggests a heart under pressure from multiple forces—being threatened.
For キョウ, imagine a threatening figure shouting 'KYO!' to intimidate you: KYO -> キョウ, and your heart 忄 feels the pressure.
