首先,来源不同compassion 来自拉丁语
sympathy 来自希腊语sympatheia
其次,用法
compassion 同情
Her heart was filled with compassion for the motherless children.
她对于没有母亲的孩子们充满了怜悯心.
I have been a prisoner,so I have a lot of sympathy with other people in prison.
我曾经是个犯人,因此我对其他在监狱里的人深表同情.
对比一下这两个句子!
还有,一般sympathy比compassion更常用!
