About

The character 窦 is a phono-semantic compound: its upper component 穴 means 'cave', 'den', or 'hole', conveying a hollow space, and the lower component 卖 ('sell') gives the sound. The traditional form 竇 uses the traditional phonetic 賣 with the same 穴 radical. Originally meaning a hole, burrow, or small drain, today it is the standard term in medical and biological terminology for an anatomical sinus or an internal body cavity. It is also a Chinese surname.
