In 威, the presence of the radical 女 hints at a power that doesn’t need shouting — the kind of composed authority that makes others stand back. Historically, the rest of the form traces to martial elements, so the whole character blends soft presence with commanding force. That’s why it spreads across words for dignity, prestige, and might.
