Explain the concept of euphemism and provide examples.

Euphemism is a linguistic device used to replace a word or phrase that may be considered too direct, harsh, or offensive with a milder or more socially acceptable alternative. It is often employed to soften the impact of sensitive or taboo subjects, to avoid causing discomfort or offense, or to convey a more positive or neutral tone.

Examples of euphemisms can be found in various aspects of daily life. Here are a few:

1. "Passed away" instead of "died" - This euphemism is commonly used to discuss someone's death in a more gentle and sensitive manner.

2. "Let go" instead of "fired" - This euphemism is often used in professional settings to describe the act of terminating someone's employment.

3. "Correctional facility" instead of "prison" - This euphemism is used to refer to a place where individuals are incarcerated as a form of punishment.

4. "Vertically challenged" instead of "short" - This euphemism is used to describe someone who is of shorter stature.

5. "Bathroom" instead of "toilet" - This euphemism is commonly used to refer to the facility where one relieves themselves.

6. "Pre-owned" instead of "used" - This euphemism is often used in the context of selling second-hand items, such as cars or furniture.

These examples illustrate how euphemisms can be employed to convey the same meaning while softening the impact or avoiding potential offense.
