Euphemism is a figure of speech that involves using a milder or more indirect term to replace a harsh, blunt, or offensive one. It is often employed to soften the impact of what is being conveyed, making it more palatable or socially acceptable. For example, saying "passed away" instead of "died" is a common euphemism used to discuss death more gently. Euphemisms can also reflect cultural sensitivities and social norms.
