About
The character 闷 (and its traditional form 悶) is a phono-semantic compound. The outer component 门 (mén, door) provides the phonetic element and suggests a spatial context. The inner component 心 (xīn, heart) forms the semantic core, visually depicting a heart confined behind a closed door. This structure directly conveys the primary meanings of physical stuffiness, as in a space lacking air, and psychological states of depression, boredom, or suppressed emotion.
