Impossible

Impossible describes something that cannot be done, achieved, or realized; something that is not possible or does not exist. It signifies a complete lack of feasibility, whether due to inherent limitations, insurmountable obstacles, or the violation of natural laws. It can refer to physical impossibilities (like flying without wings), logical impossibilities (like a square circle), or practical impossibilities (like time travel to the past).
