A euphemism is a mild or indirect word or expression substituted for one considered to be too harsh or blunt when referring to something unpleasant or embarrassing.
Here are some examples:
* "Passed away" instead of "died"
* "Let go" instead of "fired"
* "Economically disadvantaged" instead of "poor"
* "Sanitation engineer" instead of "garbage collector"
Euphemisms are often used to:
* Soften the blow: Make difficult news easier to hear.
* Avoid offense: Be polite in sensitive situations.
* Maintain social decorum: Follow social norms about what is considered appropriate language.
