About
The character 愠, derived from its traditional form 慍, is a phono-semantic compound. Its left side features the semantic radical 忄 (heart), which situates the meaning within the domain of internal emotions. The right side provides the phonetic element: in the traditional character this is 𥁕, while the simplified form uses 昷, which gives the pronunciation "yùn". The character denotes a concealed feeling of resentment or indignation, a type of anger held inward rather than openly expressed. The heart radical thus correctly places it in the realm of psychological states, specifically referring to a negative emotional burden carried within one's mind.
