The word **星光** is formed as a compound, combining the character **星** (xīng), meaning "star," with the character **光** (guāng), meaning "light" or "radiance." It is a straightforward semantic combination where the first element specifies the source and the second describes its emission, resulting in the literal meaning "starlight." This formation follows a common modifier-head structure in Chinese, where "星" modifies the type of "光," creating a single, poetic noun that evokes the delicate, distant radiance of stars in the night sky.
