A "warning" is a message or signal that alerts individuals to potential danger or risk. It serves to inform people about something that could cause harm, allowing them to take precautions or avoid certain actions. Warnings can be found in various forms, such as signs, labels, or verbal notifications. Warnings are commonly used in many contexts, including road safety, product safety, and weather alerts. For example, a traffic sign may warn drivers of a sharp turn ahead, while a label on a cleaning product might indicate that it is toxic if ingested.
