untenable

What does "untenable" mean?
The word "untenable" describes a position, argument, or situation that cannot be maintained, defended, or occupied. Imagine a soldier trying to hold a fortress that is crumbling under heavy fire; because the position is physically or strategically impossible to keep, it is untenable. It is most frequently used in formal or academic contexts to describe theories that have been disproven or living conditions that have become unbearable. You will often hear it paired with nouns like "position," "situation," or "argument." Use it when you want to sound precise about something that has reached a breaking point.
