Origin

This character combines the radical for disease or illness on the left with a component meaning "bright" or "open" on the right. The right component also serves as a sound hint for pronunciation. Together, the two parts create an image of an illness that manifests visibly on the body—a swelling or boil that appears as an open, obvious problem on the skin. The combination of "disease" plus this descriptive element captures the idea of a raised, inflamed growth.
