"Warn" refers to the act of informing someone about a potential danger or risk. It is a way to alert individuals to be cautious or to take preventive measures. Warnings can be verbal, written, or visual, and they are often used in various contexts, such as safety instructions, weather alerts, or product recalls. Warnings are important in many areas, including public safety, health, and consumer protection. For example, warning labels on products inform users about possible hazards, while weather warnings help people prepare for severe conditions. Effective warnings can help prevent accidents and save lives.
