If you hear the word "precaution," it means doing something before a potential problem happens to prevent or lessen the impact of that problem. For example, if you're going to go swimming, putting on sunscreen to protect your skin is a precaution to prevent sunburn. Or if you're cooking, using oven mitts to handle hot pots and pans is a precaution to prevent burns. Basically, a precaution is taking action to avoid something bad from happening.
