Is there a word that describes something as conditionally true? Is there a word that is used to define or describes something that's conditionally true, something whose truth is contingent on other things being true?
Not really. We have the adjectives "true" and "false", and we can use modifiers like "maybe" or "sometimes"
So "Grass is green" is true. But "Apples are green" is sometimes true.
You can abbreviate this to "True False or Sometimes".
In formal logic, an statement statements are either true or false, and so quantifiers are used:
All grass is green.
There exists at least one green apple.
It is not the case that all apples are green.
These are all true.
