lady
姮 centers on a lady or a woman of status. The single given meaning is straightforward, with no broader conceptual cluster to synthesize.
姮 combines 女 (woman) with 亘, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound for a female-related term.
A woman 女 beside the distinctive shape 亘: picture a lady standing next to a decorative screen or emblem that marks her status.
For コウ, imagine a lady named Kou standing gracefully beside the 亘 shape: Kou -> コウ, and she is the lady of the house.
