Euphemism

Euphemism (/ˈjuːfəmɪzəm/) is an innocuous word or expression used in place of one that may be found offensive or suggest something unpleasant.[1] Some euphemisms are intended to amuse, while others use bland, inoffensive terms for concepts that the user wishes to downplay. Euphemisms may be used to mask profanity or refer to taboo topics such as disability, sex, excretion, or death in a polite way.[2]
