The word "天璇" is formed by combining the character "天", a pictograph representing the sky or heaven, with "璇", a phono-semantic compound character where "玉" (jade) provides the semantic meaning of preciousness and "旋" offers phonetic cues; together, they create a compound meaning "heavenly jade" specifically used to name the star Merak in the Big Dipper, indicating its celestial and valuable attributes.
