|The key to not losing them is owning a good keychain.|
This verb is used quite often in the English language, and can be used in several ways. It's a great word to use if something is missing, either literally or figuratively. If you're forgetful you may say that you always "lose your keys", just as you can say that you've "lost your mind" if you think you've gone crazy. Lose is also the opposite of win.
If the knot holding your shoelaces together is falling apart, your tooth is awfully wiggly, or your pants won't stay around your waist, you might be in need of this adjective. Loose is often used to describe things that aren't how they probably should be. You certainly don't want someone's loose tongue to cause them to reveal the secrets of your loose morals. The word is also occasionally combined with let to form the verb let loose, meaning to "set free" or "release". You probably don't want to find out that someone has let a bat loose in your room, for example.
