Origin

This character combines wood (the left component) with a component on the right that suggests bundling or binding things together. The character originally depicted wooden poles or logs arranged and bound tightly to form a barrier, which is the core meaning of fence or stockade. The sense of things being entwined or wrapped around comes naturally from the image of materials lashed or woven together to create an enclosure. Over time, the character extended to related meanings like a weir (a fence-like barrier in water) and the feeling of being caught or entangled.
