Laws are rules that help people live together safely and fairly. They tell us what we can do and what we should not do. People follow laws at school, in their towns, and in the country. But talking about laws doesn’t always have to be serious or boring. Sometimes, people use idioms—special phrases that don’t mean exactly what the words say—to talk about law in fun or smart ways.
Idioms about law can help us understand tricky ideas in simple ways. These idioms are often used in everyday conversations.
