U+51D2 "凒" CJK Unified Ideograph-# Unicode Character

U+51D2 "凒" CJK Unified Ideograph-# is a rarely used Chinese character that has traditionally been associated with the meaning of cold or frost, essentially denoting the biting chill of winter or icy conditions. Its structure combines the two-dot water or ice radical on the left with the phonetic component 豈 on the right, reflecting its classical link to freezing temperatures and frosty atmospheres. While it is not commonly found in modern everyday Chinese or Japanese usage, it appears in some classical texts and dictionaries as a variant or less familiar term for cold, often interchangeable with characters like 凝 or 凜. In the Unicode standard, it is encoded under the CJK Unified Ideographs block, representing a historical linguistic artifact of East Asian written culture.
