About
The character "凸" is a pictograph whose structure directly depicts a convex or protruding shape, originating from a straightforward graphical representation of an object bulging outward. Its etymology is based solely on this visual analogy, and it has consistently functioned as a standalone component representing the concept of convexity. Over time, its usage has extended from describing physical shapes to serving in more abstract compounds, but its core meaning as indicating a raised or protuberant form has remained stable.
