Do you remember that we spoke about euphemisms (in German: ‘beschönigende Umschreibungen’) some time ago? And why we use them?
Here’s a quick a reminder. There are certain topics we often don’t like talking about, because they make us feel uncomfortable. And to avoid using these rather harsh-sounding words, we choose to use more positive and polite-sounding ones.
So instead of saying that someone is “homeless”, one can say that he or she is “on the streets”. And instead of saying that someone has “died”, you might say someone has “kicked the bucket”.
Even if you don’t use these expressions yourself, and I suggest you don’t if you want to be understood internationally, you might hear them and not know what is meant.
