undestroyable
Immune to annihilation
Undestroyable means impossible to destroy—able to withstand any attempt at destruction.
The word functions like indestructible but with a slightly different emphasis: indestructible suggests inherent durability, while undestroyable emphasizes resistance to active destruction: The bunker was essentially undestroyable by conventional weapons.
The word is less common than indestructible but appears in contexts emphasizing survival against deliberate attack.
