U+58D2 "壒" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

壒

U+58D2 "壒" CJK Unified Ideograph-# is a rare and complex Chinese character that typically signifies dust, dirt, or a fine powdery substance, often associated with accumulated grime or atmospheric particles. It is composed of the radical for earth or soil, 土, on the top, and the phonetic component 蓋 (meaning cover or lid) beneath, which gives it its pronunciation, generally read as "ài" in Mandarin. This character is not commonly used in modern everyday Chinese writing but can appear in classical literary contexts, historical texts, or specialized terminology related to environmental or descriptive imagery. Its precise meaning may vary in ancient or poetic usage, where it sometimes conveys a sense of obscured or muted conditions, such as dusty air or a soiled surface.
