U+5B51 "孑" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
孑
U+5B51 "孑" CJK Unified Ideograph-# is a Chinese character that traditionally signifies loneliness, solitude, or the state of being alone, often seen in classical texts and modern usage as a component in compound words. Its structure evokes the image of a single, isolated person, and it appears in terms like "孑然一身" (jiérán yīshēn), meaning "all alone" or "solitary." This ideograph is part of the Kangxi radicals under the radical 子 (child) and carries minimal strokes, making it a concise symbol for separation or the end of a lineage, though it also appears in scientific contexts such as in the name of the mosquito genus "Anopheles" via the character "孑孓" (jiéjué) for wrigglers.
