U+51D8 "凘" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

凘

U+51D8 "凘" CJK Unified Ideograph-# is a Chinese character that appears in the standard CJK (Chinese, Japanese, and Korean) ideograph block, defined primarily for traditional and classical Chinese scripts. This character, pronounced "sī" in Mandarin, is associated with the concept of melting ice or drifting snow, often used in literary or archaic contexts to describe the gradual dissolution of ice or the flowing of melting snow. Its composition typically includes the "ice" radical (冫) on the left, indicating a connection to cold or frozen water, and a phonetic component on the right, though it remains a rare character in modern Chinese, used infrequently except in specialized or historical texts.
