U+566B "噫" CJK Unified Ideograph-# Unicode Character
U+566B "噫" CJK Unified Ideograph-# is a Chinese character that functions primarily as an interjection or exclamatory particle in classical and modern Chinese, often expressing sighing, regret, admiration, or surprise depending on context. Its pronunciation in Mandarin is "yī" or "ài," and it appears in classical texts such as the Analects of Confucius, where it conveys a tone of lamentation or exclamation. The character structurally combines the "mouth" radical (口) with the phonetic component "意" (yì), reflecting its use as a sound-based utterance. In Japanese, it is also used as a kanji representing an interjection of alarm or wonder, though it is less common in everyday writing. Overall, 噫 exemplifies how written Chinese encodes nuanced emotional vocalizations through logographic composition.
