About
The character 鎋 is a phono-semantic compound, with the metal radical 金 on the left indicating its semantic category, and 害 on the right providing the phonetic element. It serves as an orthographic variant of 轄. The metal radical specifies that the object, a linchpin, the essential pin securing a wheel on an axle, is made of metal. While 轄 employs the vehicle radical to highlight the pin's function on a cart, 鎋 uses the metal radical to emphasize its material composition.
