This document discusses euphemisms, which are polite or indirect words used to discuss embarrassing or difficult topics. It provides examples of euphemisms used instead of more direct but potentially offensive terms, such as "put down" instead of "killed" for a sick pet, or "senior citizen" instead of "old person". Over time, euphemisms themselves can become offensive as attitudes change, so new indirect terms are often adopted. While euphemisms aim to soften language, some argue they can undermine recognition of serious issues.
