Got Proof?

In today's blog, I'd like to focus on some vocabulary containing the word proof. In the comic strip, the rat asks the flight attendant to “put all the babies in a soundproof box.” Soundproof means not allowing sound to go through. The reason why the rat asks for that is because babies tend to cry on a plane and make a lot of noise and so other passengers can't sleep. But, of course, that's not possible.


Here is a list of some common vocabulary containing the word proof:


1. soundproof (doesn't let sound through; 防音)

examples: a soundproof room, a soundproof wall


2. waterproof (doesn't let water through; 防水)

example: a waterproof sleeping bag


3. bulletproof (doesn't let bullets through; 防弾)

examples: bulletproof glass, a bulletproof vest


4. fireproof (can't be damaged by fire, 防燃)

example: a fireproof safe


5. childproof (can't be opened by a child; 小児用安全)

example: a childproof container


6. foolproof (so simple to understand that it can't go wrong; 馬鹿よけ)

examples: a foolproof system, a foolproof camera


7. shockproof (not easily damaged if hit or dropped)

example: a shockproof watch
