unsupportable
Beyond reasonable defense
Unsupportable means unable to be supported or defended.
An unsupportable claim lacks evidence; an unsupportable position cannot be justified.
The word applies to arguments, theories, or burdens that cannot be sustained: The cost became unsupportable.
It carries more force than *weak*—something unsupportable collapses under scrutiny.
