What if I now tell you that in some cases, PROOF can also mean to protect from. Here’s one example. You have planned to go trekking yet the news is forecasting rain. One possibility is to cancel the trek, the other is to bring out your WATERPROOF gear – shoes, trousers and jacket that keep you dry by not allowing the water to penetrate. These clothes protect you from the wet weather.
Another situation. Famous people, from movie stars to politicians, often go around with bodyguards, people trained to protect them from anyone who might try to hurt them. These bodyguards often wear a special top, maybe under their shirts or jackets, which can stop a bullet if someone fires a gun in their direction. This top or vest is made from BULLETPROOF material. Even the windows of cars belonging to VIPs (very important people) can be made with BULLETPROOF glass.
