About
The character "窿" is structured as a phono-semantic compound, combining the radical "穴", which indicates a cave or hollow space, with the component "隆", serving primarily as a phonetic element. Its etymology points to an original sense of deep cavities or apertures, often used in architectural or anatomical contexts to describe pronounced hollows. Over time, its semantic range broadened to encompass a variety of perforations or voids, from nostrils to gaps in materials, while retaining its core association with empty spaces. The traditional form, maintaining these constituent parts, has thus preserved a conceptual continuity even as the character's usage adapted to more generalized and metaphorical applications in the language.
