灰尘

• 拼音: huī chén
• 汉字拆解: 灰 = 火 + 又 (fire + hand, ash left after fire); 尘 = 小 + 土 (small + earth, fine earth particles)

含义

Dust; fine particles of dirt or debris that settle on surfaces.

Refers to the fine dry particles that accumulate on surfaces over time. Used both literally and metaphorically. Metaphorically, 灰尘 can represent the passage of time, neglect, or obscured memory (as in objects covered in dust suggesting long disuse).
