The word "粼粼" is formed by duplicating the single character "粼", which is a phono-semantic compound consisting of the semantic component "巜" (derived from "川", meaning water or stream) on the left, indicating its association with water, and the phonetic component "粦" (pronounced lín) on the right, providing its sound; this duplication creates a reduplicated adjective that emphasizes a visual effect, specifically describing the clear, shimmering, or rippling appearance of water.
