U+6004 "怄" CJK Unified Ideograph-# Unicode Character

U+6004 "怄" CJK Unified Ideograph-# is a Chinese character that primarily means "to sulk" or "to be irritated" in modern Mandarin, often conveying a sense of suppressed anger or annoyance. It is composed of the radical 忄 (heart/mind) on the left, indicating an emotional or psychological state, and the phonetic component 区 on the right. Historically, it appears in classical texts and is still used in contemporary Chinese, though less common in formal writing, to describe a feeling of being secretly vexed or resentful without open expression. Its structure and usage reflect traditional CJK principles where radicals and phonetic elements combine to form meaning and sound.
