If you're unsure of whether to buy the car, you may ask for more information about it. Information is knowledge you gain from studying, investigating, or experiencing something.

If your brother unfairly accuses you of finishing the ice cream that was in the freezer, you might respond by saying, "For your information, it was already gone when I got home!"
