Cách sử dụng
The expression "forewarned is forearmed" means that if you are aware of a potential danger or problem beforehand, you are better prepared to deal with it when it happens. It is like having a weapon to defend yourself against something you already knew was going to happen. You can use this expression when you want to say that it's important to be informed and aware of possible risks so you can take precautions and avoid negative consequences. For example, if you know there's going to be bad weather, you can prepare by bringing a coat or an umbrella, so "forewarned is forearmed" in that situation.
