The kanji 滉 is a phono-semantic compound (形声文字, けいせいもじ). It combines two elements: ⚫︎ The radical 氵 (さんずい, sanzui), which represents "water." This indicates that the kanji has a connection to water. ⚫︎ The phonetic component 黄 (こう, kō), which means "yellow" or "gold," and in this context, contributes the sound and hints at the sense of brightness or brilliance, as gold can often reflect light, so it is connected to water. The combination of these two elements creates a character that describes water's brightness or the light reflected from water.
