Meaning & readings

stratum, social class, layer, story, floor

On’yomi ソウ

Origin

The character combines two parts to show the idea of layers stacked on top of each other. The left component 尸 is a classifying marker that suggests something structural or built. The right component serves as a sound hint, telling you roughly how to pronounce the character. Together, these parts suggest horizontal divisions or strata — think of how floors in a building stack upward, or how social classes arrange themselves in layers. This visual idea of stacked, separated sections is why came to mean layer, stratum, floor, or social tier.
