Origin

This character combines flesh or body (the 月 component at the bottom, which in this context classifies characters related to the body) with a sound hint at the top that suggests the pronunciation キョウ. The idea is that to threaten or coerce someone, you might grab or pressure their body—the physical component signals the action involves the body, while the top part tells you how to pronounce it. Over time, the character came to mean the abstract idea of threatening or intimidating rather than just a physical action.
