The word "琳琅" is formed by combining the characters "琳" and "琅", both of which independently refer to precious jade or fine stones; "琳" means a type of beautiful jade, while "琅" denotes a kind of precious stone often linked to a clear, tinkling sound. Their pairing creates a compound where the similar semantic elements reinforce each other to convey the concept of valuable and exquisite objects, which is why the term is used to describe an array of fine things.
