U+6D1E "洞" CJK Unified Ideograph-# is a Chinese character meaning a cave, hole, or cavity, often used to describe an opening in the earth or a hollow space within an object. It is composed of the radical "氵", indicating water, and the phonetic component "同", suggesting its pronunciation in Mandarin as "dòng." This character appears in various contexts, including geographical terms like "洞穴" for cave, philosophical metaphors such as "洞察" for insight or penetrating observation, and even modern phrases like "黑洞" for black hole.
