The word 鳞片 is formed by combining two characters: 鳞, which uses the radical 鱼 (fish) to indicate its category and the component 粦 primarily for pronunciation, meaning "scale", and 片, a pictographic character depicting a thin slice, meaning "piece" or "flake". Together, they create a compound noun where 片 specifies the thin, plate-like shape, resulting in the meaning "scale" as in the overlapping plates on an animal's skin.
