About
砾 is a phono-semantic compound, written traditionally as 礫, with the semantic radical 石 (stone) on the left indicating its material category and the phonetic component 樂 on the right. In the simplified form, the phonetic element is reduced to 乐, but the structural logic remains the same. The stone radical specifies that the character refers to fragmented rock materials, gravel, pebbles, or crushed stone, distinct from solid boulders or fine dust. It often appears in geological or architectural contexts to describe sedimentary particles and commonly pairs with characters like 沙 to form words for granular stone mixtures.
