Impeccability

Impeccability means doing something perfectly, almost like a superhero would do it. Imagine that you are coloring a picture and your teacher asks you to color inside the lines. If you color inside the lines perfectly and don't make any mistakes, then you are being impeccable.

Or, let's say you are playing a game with your friends and you follow all the rules exactly as they are written without making any mistakes, then you are being impeccable. It means that you are doing something without making any mistakes, and you are doing it perfectly. It may not always be easy to be impeccable, but when you do it, it can make you feel proud of yourself.
