表示责任的几个词duty responsibility liability有什么区别

obligation指“一个人在特定时间内必须尽的义务或责任”,如:To pay taxes is anobligation。纳税是一种义务。duty 指“按道德、法律、社会习惯或良心应尽的本分、义务和责任”,着重“自觉”,如:Don't forget your duty to your parents。不要忘记对父母的责任。responsibility 指“由于法律、职业或道德等方面的要求,而应尽的责任或义务”,着重“必须对后果负责”,如:accept full responsibility for one's error 对自己的错误负完全责任。liability 十分类似于responsibility,时常是难以区分使用,主要是侧重于责任义务的合法性,多用于money相关话题。如,Tenants have leagal liability for any damage they cause。
