About
The character 阍 is constructed from the semantic radical 門, meaning "gate", and the phonetic component 昏, which indicates its pronunciation and may originally have implied the dusk hour associated with closing gates. Its earliest attested meaning was specifically a gatekeeper, often for palaces or official residences, but over time the term also came to refer to the guarded gate or entrance itself. In its traditional form, the character retains this composition of 門 and 昏, with the radical clearly denoting its association with doorways and access points.
