unturnable
Unturnable is a term used to describe something that cannot be turned or rotated. This can apply to physical objects as well as abstract concepts. For instance, a cylindrical object with a perfectly uniform diameter along its length might be considered unturnable in the sense that rotating it would not change its appearance or orientation relative to its surroundings. In a more literal sense, a securely fastened bolt or a rigid, fixed structure could be described as unturnable.
The concept of unturnable also extends to situations where a decision or course of action is irreversible.
The opposite of unturnable is turnable, which signifies the capacity to be rotated or changed. Understanding
