When do you use euphemism?

Euphemisms are used to soften the impact of difficult or uncomfortable topics, making them more palatable or socially acceptable. They are often employed in sensitive situations, such as discussing death, illness, or personal failure, to avoid causing distress or offense. Additionally, euphemisms can help maintain politeness and decorum in conversations, particularly in formal or professional settings. Ultimately, they serve to convey messages in a more tactful manner.
