人们对生死、地震、雷、电和火山等自然现象的不理解和恐惧，而产生了迷信，对神灵进行崇拜，因此在言语中不敢冒犯和触怒神灵，神名被视做神的化身，人们不敢直呼其名,而必须用其他委婉的词语来称呼神名。比如，按罗马神话中的主神朱庇特的职务来称之为The Thunderer(雷神)，而那位蛇发石心，身穿黑袍，手执鞭剑，火把的“复仇女神”真名为the Furies，就通常被称为the Eumenides（意为kingly ones或friendly慈善之神或友好之神）美国诗人郎费罗（Longfellow）在他的诗《收割者和花朵》（“The Reaper and the Flower”）中写道：“There is a Reaper whose name is Death,and,with his sickle keen,he reaps the bearded grain at a breath,and the flowers that grow between. ” (有个收割者名叫死亡，他挥动起锋利的大镰刀，一口气割下一行行带须的谷物，也割下了其间的各种花朵。)这里的死神被很形象地称为reaper（收割者），这些对神称呼的委婉语是非常多的，因为人们希望能用委婉语来安抚这些可怕的神，使灾难不会降临到自己身上。

About life and death, earthquakes, mine, electricity, volcanoes and other natural phenomena do not understand and fear, and have had a blind faith, worship for the gods, so in the speech did not dare offend the gods and offend God were to do as the incarnation of God, People did not dare address him by name, and must be tactful in other words to describe God's name. For example, according to Roman mythology the god Jupiter main functions to be called The Thunderer (Raytheon), and that made Stone a snake heart, dressed in black, Zhibian sword in hand, the torch of the "Nemesis" I called the Furies, often called on the Eumenides (which means friendly or kingly ones charitable god or the god of friendly) poets of the United States Henry Wadsworth Longfellow (Longfellow) in his poem "harvest and flowers" ( "The Reaper and the Flower" ) Wrote: "There is a Reaper whose name is Death, and, with his sickle keen, he reaps the bearded grain at a breath, and the flowers that grow between." (There is a reaper by the name of death, he waved From the sharp scythe, and his breath cut line with the required grain, but also a cut during a variety of flowers.) Here is the image of death to be known as the reaper (harvest), which called on God is the euphemism Very much, because people would like to use euphemisms to placate these terrible God, so that a disaster will not come to them.
