塵

Physical particulate matter—specifically light, airborne, or settled particles such as dust, dirt, ashes, or cinders. In Buddhist and philosophical contexts, it serves as a metaphor for the mundane world (塵世), sensory distractions, worldly attachments, and the bustle of secular life (e.g., 紅塵 "red dust").

Functions almost exclusively as a noun. It does not typically function as a verb; concepts like "becoming dusty" usually require accompanying verbs such as 積 (accumulate) or 染 (stain/infect). Where the glyph appears to act as a predicate, it may be shorthand for being embroiled in worldly affairs.

Compared to 垢 (grime/filth), this glyph refers to lighter, settled, or airborne particles. Compared to 埃 (dust), which often emphasizes microscopic motes driven by wind, this glyph more frequently suggests settled matter or the conceptual weight of worldly distraction.

Simplified variant: U+5C18.

In handwritten texts or manuscripts, be alert to the omission of the earth radical (土). If 辰 (the dragon/time marker) appears in a context where a chronological reference is nonsensical, it may be a misspelling of 塵.
