Meaning & readings

deluge, flood, vast

On’yomi コウ
Nanori ほん

Origin

The character combines water on the left side, which marks it as relating to water phenomena, with a sound component on the right that hints at the pronunciation. The water radical specifically suggests a large body of water, and pairing it with the sound hint creates a character meaning a massive flood or deluge. Over time, the meaning expanded from the literal image of vast water to describe anything that is abundant or overwhelming in scale.
