“一贫如洗”，字面意思是穷得像用水洗过似的，什么都没有（so poor as if everything had been washed away）。形容十分贫穷，可以翻译为“be utterly destitute，poor as a church mouse或poor and bare to the bones”。
例句：
他死时家里一贫如洗。
When he died, his family was left completely destitute.
你知道我一贫如洗，没有家产。
You know how hard up I am, with no property of my own.
