Euphemism

A euphemism is the substitution of a potentially offensive or unpleasant word or expression with one that is more pleasant or inoffensive. Some euphemisms are humorous, while others use mild or neutral language to downplay certain concepts. They can often be used to soften profanity or discuss sensitive or taboo topics, such as disability, sex, bodily functions, pain, violence, illness, or death, in a more polite manner.
