U+581B "堛" CJK Unified Ideograph-# is a Chinese character primarily used in historical or classical contexts, representing a term for a "clod of earth" or a "lump of soil," often associated with agricultural or geological descriptions. Its structure combines the earth radical (土) on the left, indicating its relation to soil or ground, with a phonetic component on the right, reflecting its pronunciation in Middle Chinese and certain modern dialects. While not commonly used in contemporary Mandarin, it appears in older literary texts and dictionary entries, where it denotes compacted earth or a mound. The character is classified under the Kangxi radical 32 (土) with 12 additional strokes, and in the Unicode standard, it belongs to the block for CJK Unified Ideographs, supporting legacy East Asian writing systems.
