U+5455 "呕" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

呕

U+5455 "呕" CJK Unified Ideograph-# is a Chinese character that primarily means "to vomit" or "to emit," and it is commonly used in modern Mandarin to express the act of throwing up, often in medical or everyday contexts, as in the word 呕吐 (ǒutù) meaning "vomit." This character belongs to the CJK (Chinese, Japanese, and Korean) unified ideographs block and carries the radical 口 (mouth), reflecting its association with oral or expressive actions, though its phonetic component "区" (ōu) indicates its pronunciation. Historically, it has also been used in classical texts to denote the sound of spitting or an exclamation of disgust, tying its visual form to both physical expulsion and metaphorical rejection.
