‘雾散’ literally means ‘fog disperses’ and describes the natural process where fog lifts or clears, often at dawn or after a change in weather. The first character 雾 (wù) means ‘fog’ or ‘mist’, while 散 (sàn) means ‘to disperse’, ‘to scatter’, or ‘to dissipate’. Together, they form a compact two-character verb phrase that emphasizes the gradual vanishing of fog—typically used to evoke atmosphere, transition, or clarity emerging from obscurity.

This phrase is common in descriptive writing, poetry, and weather reports. It’s not used for human-made smoke or steam (those require other verbs like ‘消散’ or ‘蒸发’), nor is it typically applied metaphorically without context (e.g., ‘confusion disperses’ would use ‘消散’ instead). While grammatically a verb, ‘雾散’ often appears as a predicate or in time clauses (e.g., ‘雾散后，阳光洒满山谷’), and rarely functions as a standalone noun.
