More About Waterproof

What does waterproof mean?

If something is waterproof, water can’t soak it or get inside of it. For example, waterproof boots will keep your feet dry even if you walk in water.

Waterproof is also commonly used as a verb meaning to make something waterproof, as in We need to waterproof this basement so it won’t flood during rainstorms. 

Waterproof is sometimes used in the U.K. as a noun to refer to a waterproof garment, especially a raincoat, as in It’s raining, so you’d better wear your waterproof.

Example: Make sure you get a waterproof tent—the ones that are only water-resistant can still let the rain in.

Where does waterproof come from?

The first records of waterproof come from the 1600s, but it wasn’t used in its current sense until the 1700s. The suffix -proof means “impervious or resistant to,” and is used in words like fireproof and bulletproof.

If something is waterproof, it means it is completely impervious or resistant to water—water won’t damage it, penetrate it, or otherwise change it. Sometimes, there’s no harm in getting wet, but water can damage things (like electronics) or make them uncomfortable (like socks). A lot of outdoor gear, like gloves, boots, and raincoats, is often labeled as waterproof or water-resistant, but these two things are not the same. If you want a raincoat that is truly impervious to all water, you want a waterproof one. Water-resistant means it will repel water but some water may still be able to penetrate the surface. Of course, truly waterproof items are often more expensive.
