Origin

This character combines the idea of an enclosed or bounded space (the box-like component on the left) with a mountain or hill (山, the three peaks shown on the right). Together, these parts suggest a hill or elevated area that is somehow distinct or set apart—a mound or knoll rising within a landscape. The mountain component carries the primary sense of height and terrain, while the enclosing frame emphasizes that this is a particular, identifiable geographical feature rather than just any elevation. Over time, the character came to mean any hill or small mountain.
