What does "euphemism" refer to?

A euphemism refers to a mild or indirect word or expression that is used in place of one that may be considered harsh, blunt, or offensive. This literary device allows speakers or writers to soften the impact of their words, making it easier to address uncomfortable or sensitive topics without causing offense or distress. For instance, using "passed away" instead of "died" is a classic example of a euphemism; it conveys the same idea in a gentler manner. This technique is frequently employed in various contexts, such as politics, social issues, and everyday conversation, to maintain politeness or sensitivity.
