The word "玲玲" is formed by reduplicating the single character "玲", which is a phonetic-semantic compound consisting of the semantic radical "王" (a variant of "玉", meaning jade) on the left, denoting its association with jade, and the phonetic component "令" (pronounced líng) on the right, indicating its sound. This duplication creates a disyllabic word that specifically imitates the tinkling sound produced by jade, serving as an onomatopoeic term.
