The word 珠宝 is formed by combining two characters, each contributing a key concept: 珠 (zhū), which originally means "pearl" but here represents jewels or precious stones, and 宝 (bǎo), which means "treasure" or something of great value. Together, they create a compound idea where the first element specifies a type (jewels) and the second elevates it by declaring its treasured status, resulting in the comprehensive meaning of "jewelry" or "precious gems". It is a conceptual fusion where the whole meaning is greater than and derived from the sum of its visual and semantic parts.
