A warning is a signal that something might happen or cause trouble if we don't pay attention.
When people give warnings, they usually want us to know about a potential problem so we can avoid it. For example, a weather forecast might include a warning for strong winds or heavy rain, urging people to stay safe indoors. A doctor might warn a patient about the risks of certain medications or medical procedures. Even at school, teachers often give warnings to students about misbehaving or not following rules. The main idea is that a warning helps us prepare and take precautions, so we can stay out of trouble.
