"the dust settle "的定义和意义

What is the origin of the idiom "let the dust settle" and when to use it?

The origin of the phrase "let the dust settle" can be traced back to literal dust settling after a disturbance or commotion, such as a battle or a construction activity. When dust is stirred up, it takes some time for the particles to settle back down and for visibility to improve. This literal concept of waiting for the dust to settle eventually evolved into a metaphorical expression. It is employed to suggest the importance of allowing a period of time for emotions to calm down, tensions to ease, or chaos to subside before making decisions or taking further action.
