manslaughter就是非murder的杀人呗，挺好理解啊。

说明英语词汇来源广泛

DescriptionManslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th century BC. The definition of manslaughter differs among legal jurisdictions. Wikipedia

英语构词就是个缝合怪，什么来源都有

英语也是野蛮生长过的语言，词源混乱，一词多义，语法不规律，叙述的不精确度在常用语言中仅次于中文。

manslaughter这个词是很容易误解。
