"Impenetrable" Natural Recordings by Native Speakers
Impossible to penetrate or enter; inaccessible or difficult to understand.
Impenetrability refers to the quality of being difficult to understand, penetrate, or access, often due to being complex, obscure, or protected by barriers. In a literal sense, it refers to the property of an object or material that is resistant to penetration, such as a fortress's impenetrable walls.
