Origin

The character combines a gate or door radical (門) with a sound component (伐) that hints at pronunciation. The gate imagery suggests enclosure or boundary, which connects to the idea of a closed group of people — a clique or faction that draws lines between insiders and outsiders. The enclosed nature of a gate mirrors how clans and lineages function as bounded social units with their own internal hierarchy and rules. Over time, this visual metaphor of a "gated group" came to represent the concept of organized factions and family-based power structures.
