The term euphemism refers to polite, indirect expressions which replace words and phrases considered harsh and impolite or which suggest something unpleasant.
Euphemism is an idiomatic expression which loses its literal meanings and refers to something else in order to hide its unpleasantness. For example, “kick the bucket” is a euphemism that describes the death of a person. In addition, many organizations use the term “downsizing” for the distressing act of “firing” its employees.
