U+5540 "啀" CJK Unified Ideograph-# Unicode Character

U+5540 "啀" CJK Unified Ideograph-# is a Chinese character that primarily functions as a verb meaning to gnaw or to bite, often used in the context of animals, particularly dogs, chewing on bones or other hard objects. This character is composed of the radical "口" (mouth) on the left side, indicating an action involving the mouth, and the phonetic component "厓" (yá) on the right, which suggests its pronunciation. While it is not a high-frequency character in modern Chinese, it can appear in classical texts or literary descriptions of persistent gnawing or biting, sometimes carrying a connotation of anger or aggression. In the Unicode standard, it is part of the CJK (Chinese, Japanese, Korean) Unified Ideographs block, allowing it to be used across different East Asian writing systems with similar meanings and forms.
