Origin

This character combines the earth or mound radical on the left, which grounds it in physical, tangible concepts, with a sound component on the right that suggests the pronunciation. The earth radical points toward the character's connection to solid, material things — particularly private or hidden places like caves or the shadowed side of terrain. Over time, the meanings expanded from the physical idea of shade cast by a mountain or hill to more abstract concepts like secrecy, negativity, and the yin principle of darkness and concealment. The sound component is just a pronunciation guide and doesn't itself contribute to the meaning.
