As a phono-semantic compound, 濠 combines the water radical 氵, indicating its semantic category, with 豪, providing its phonetic value. Its primary meaning is a water-filled defensive moat surrounding a city wall. It is etymologically related to 壕, which denotes a dry ditch. The character also appears in place names, notably the Hao River in Anhui, referenced in classical texts like those of Zhuangzi.
