The word 手腕 is formed through a vivid conceptual metaphor. It literally means "hand" (手) and "wrist" (腕), the physical joint that allows the hand to turn, grasp, and maneuver with flexibility and strength. This concrete image is extended metaphorically to represent the abstract qualities of skillful method or social maneuvering, implying the same kind of dexterous, adaptable, and tactful application of influence in human affairs as the wrist provides for the hand in physical action.
