⚫︎ 琉 is a 形声文字 (keisei moji), a phono-semantic compound character. ⚫︎ It is composed of two parts: ⚫︎ The left side is a radical called 玉 (gyoku), meaning "jade" or "jewel". This provides the semantic (meaning) component, hinting at the gem-like nature of the character. ⚫︎ The right side is 流 (ryuu), meaning "flow." This provides the phonetic component, suggesting the sound and perhaps hinting at the way light may flow through a translucent gem. ⚫︎ The combination of these components creates the character's meaning, linking "jade" and "flow" to the concept of a beautiful, gem-like substance.
