Meaning & readings

lungs

On’yomi ハイ

Origin

This character combines the body-part classifier (a simplified form of the character for flesh or organs) on the left with on the right, which serves as a sound hint telling you roughly how to pronounce the character—like "hai." The flesh radical makes sense because lungs are an internal organ, and the sound component helps speakers remember the pronunciation. Together they form a straightforward medical term for the respiratory organ.
