river in Hubei province
灄 is a rare kanji that names a specific river in Hubei province. Its meaning is purely geographical and has no broader conceptual center.
灄 combines the water radical 氵 with the phonetic component 聶, forming a character used in a Chinese place name. The exact historical development is uncertain.
The left side 氵 (water) signals a river, and the right side 聶 (three ears) can be imagined as listening to the river's sounds. Together they name the She River in Hubei.
For ショウ, picture a person named Sho standing by the river, listening to the water with three ears: Sho -> ショウ.
