About
窦 is a phono-semantic compound with a clear spatial meaning. The semantic component 穴 (cave, den) indicates a physical cavity or hollow space, while the phonetic component 卖 provides its pronunciation. Its traditional form, 竇, pairs the same cave radical with the traditional phonetic 賣. Originally meaning a hole, burrow, or small drain, it now specifically denotes anatomical sinuses or body cavities in medical terminology. The character is also a standard Chinese surname.
