U+5FFF "忿" CJK Unified Ideograph-# Unicode Character
U+5FFF "忿" CJK Unified Ideograph-# is a Chinese character that represents the concept of anger, indignation, or resentment, often conveying a sense of internal fury or spite. Its structure combines the radical for "heart" or "mind" (心) with the phonetic component "分" (fen), reflecting an emotional state tied to division or separation. In classical and modern usage, it appears in compound words such as "忿怒" (fèn nù, meaning rage) or "不忿" (bù fèn, meaning unwilling to accept or resentful), and it is distinct from the more explosive anger of "怒" (nù), instead emphasizing a brooding or sustained bitterness. This character is part of the Kangxi radical system and is used across Chinese, Japanese, and Korean written traditions, maintaining a consistent connotation of righteous or petty indignation.
