Epitet
The epithet is based on the interplay of emotive and logical meaning in an attributive word, phrase or even sentence, used to characterize an object and pointing out to the reader some of the properties or features of the object with the aim of giving an individual perception and evaluation of these features or properties.
Euphemism
A euphemism (from the Greek words eu - well and pheme - speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions. Most people, for example, would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed. They would soften the pain by saying: We had Fido put down or We had Fido put to sleep. Many people prefer to call someone plain than ugly, or cuddly rather than fat. As such, euphemisms are an important part of every language, but it seems that English has an ever-growing number of them. The non-native speaker not only has to make sense of the euphemisms he hears, he also has to learn which euphemisms are appropriate in any particular situation. He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom, or comfort station) is, but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog. He might have learned, for example, that in the family way is a euphemism for pregnant. If he says to his boss, however: Congratulations! I hear your wife is in the family way., he would be using an expression that is too familiar for the circumstances.
