Peace means calm, quiet, and not fighting. It is something many people want in their lives. When we feel peaceful, we are relaxed and happy. We can think clearly and enjoy the moment. People talk about peace in different ways. Sometimes, they use special phrases called idioms.
Idioms are words put together that mean something different from what they sound like. For example, if someone says “calm before the storm,” they don’t mean a real storm. They mean things are quiet now, but trouble may come soon. In this article, we will learn some idioms people use to talk about peace.
