The word "璀璨" is formed by combining two characters, 璀 and 璨, each constructed with the jade radical 王 on the left, indicating a semantic connection to precious stones or jade-like qualities. The right-side components, 崔 in 璀 and 粲 in 璨, serve as phonetic elements that approximate the pronunciations cuǐ and càn respectively. When joined, these characters reinforce each other to convey the meaning of intense brightness or sparkle, specifically in reference to glittering objects such as gems or stars.
