A euphemism is a mild or indirect word or expression substituted for one considered to be too harsh or blunt when referring to something unpleasant or embarrassing.

For instance, saying ‘passed away' instead of ‘died' softens the impact.

We only “fire” someone if they were a truly terrible employee. Otherwise we say, “We have to let you go,' or “This just isn't working out.”

Instead of revealing unwanted details about our excretory functions, we say, “I need to use the restroom.”

Even “restroom” is a euphemism. And so is “bathroom.” When you need a bath you don't tell people you want to use the bathroom, and you don't go in there to rest, either.

“Making love” is definitely a euphemism.

In public speaking, euphemisms make your language more palatable and respectful, especially in delicate situations—though overuse can lead to vague or unclear communication.

The key to using euphemisms effectively is balance.
