追根溯源

在罗马神话中,死神叫做摩尔斯(Mors),摩尔斯的形象经常被描绘为身着黑色长袍,手持长柄镰刀,用来砍倒将死之人。从摩尔斯的名字 Mors 产生了英语词根 mort,表示“死亡”。

单词 mortality 里的 mort 部分,就来源于词根 mort。英语中,包含 mort 的单词,多与“死亡”相关,例如:

mortal  /ˈmɔːtl/

adj.凡人的;致死的

immortal  /ɪˈmɔːtl/

adj.不死的;神仙的

mortify  /ˈmɔːtɪfaɪ/

vi.禁欲;苦行

mortician  /mɔːˈtɪʃn/

n.殡葬业者;丧事承办人

mortuary  /ˈmɔːtʃəri/

n.太平间;停尸间

同近义词
fatality: A fatality is a death caused by an accident or by violence.(死亡)

death rate: The death rate is the number of people per thousand who die in a particular area during a particular period of time.(死亡率)
