The term "unexploded" refers to something that has not yet gone off or detonated, despite being exposed to a potentially explosive situation. This could be an unused bomb, grenade or other explosive device that did not ignite when it was supposed to, either because the fuse failed to burn properly or because someone managed to defuse it before it went off. The word "unexploded" is often used in relation to munitions and ordnance left over from wars or conflicts, which can pose a danger to people and animals if they are not safely removed and disposed of.
