U+51DF "凟" CJK Unified Ideograph-# Unicode Character

U+51DF "凟" CJK Unified Ideograph-# is a rare and highly specific Chinese character meaning "to be muddy," "to be turbid," or "to be unclear," often describing water or abstract confusion. It belongs to the traditional Chinese script and is composed of the "water" radical (氵) on the left and the phonetic component "賣" (mài, meaning to sell) on the right. This character is historically attested but extremely obscure, rarely appearing in modern texts, and its use is limited mainly to classical literature or highly specialized dictionaries. It resides in the CJK Unified Ideographs block of the Unicode standard, encoded alongside thousands of other logographic characters for East Asian languages mostly within UTF 16.
