The word "impenetrable" means something that cannot be penetrated or passed through, usually used to describe objects that are too dense or too thick to go through. For example, a wall that is very thick and cannot be broken through is impenetrable. It can also be used to describe something that is very difficult to understand or access, like the mind of someone who keeps their thoughts hidden or a complex concept that is hard to grasp. It can be used to describe physical objects or abstract ideas.
