Origin

This character combines a wheel or vehicle radical on the left with a sound hint on the right. The wheel component suggests something related to carts or axles, while the right side provides a pronunciation guide. A wedge or axle pin is a crucial part that holds a wheel in place on a cart, which connects to the idea of controlling or securing something. The character's form evolved to express this notion of control through the mechanical image of a restraining device on a vehicle.
