Origin

The left side is a radical meaning "mound" or "earth," which establishes this as a word about landforms. The right side, 反, suggests something turned or opposed. Together, they picture a slope or height of earth — a rise in the land where the terrain goes up. This combination makes sense for describing hills, slopes, and elevated areas, since a slope is where flat ground and a raised mound meet in opposition.
