impervious

What does "impervious" mean?
The word "impervious" describes something that cannot be penetrated, affected, or influenced. Imagine a high-quality raincoat that is "impervious to water"—the rain hits the surface and simply beads off, leaving the wearer completely dry underneath. In a figurative sense, we use this to describe someone who is unmoved by criticism or emotion. If a person is "impervious to reason," it means they are stubborn and refuse to listen to logic, as if their mind has a protective shield that blocks out any external input.
