U+6B57 "歗" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

歗

U+6B57 "歗" CJK Unified Ideograph-# is a rare and traditional Chinese character that primarily means "to whistle" or "to howl," often associated with a long, shrill sound made by mouth or wind. It is closely related to the more common character "嘯" (xiào), which shares the same meaning and phonetic component, and is used in classical Chinese literature to describe the sound of wind or the human act of whistling in a resonant, expressive manner. This character falls under the Kangxi radical 76 "欠" (qiàn), meaning "to lack" or "to yawn," which contributes to its semantic field of vocal expressions. In modern usage, "歗" is largely archaic and has been supplanted by "啸" in standard simplified Chinese, though it occasionally appears in historical texts, calligraphy, or contexts referencing classical poetry and philosophy.
