U+51D0 "凐" CJK Unified Ideograph-# Unicode Character

U+51D0 "凐" CJK Unified Ideograph-# is a relatively rare Chinese character that primarily conveys the idea of "cold" or "icy" in a meteorological or thermal sense, often referring to the extreme chill of frost or a frigid landscape. Its structure combines the ice radical 冫 with the phonetic component 垔, linking it to concepts of freezing or solidifying moisture. While not commonly used in modern standard Chinese, it can appear in classical texts or specialized contexts related to weather, winter conditions, or poetic descriptions of bitter cold. This character is encoded in the CJK Unified Ideographs block of the Unicode Standard, ensuring its representation for digital communication and preservation in historical or literary documents.
