possible situation
A way things could be, whether or not they actually are that way.
A possible situation is any complete, consistent way the world could be. It may match the actual world or differ from it. Logic uses possible situations to ask what a claim would be like if things were different, which is how validity is tested.
Examples
A situation where it snowed in Miami yesterday is possible, even if it didn't happen.
A situation where a triangle has four sides is not possible: the description contradicts itself.
