When "just" is an adjective, I have always seen it used as an attributive one (ie, before a noun). Examples:
- a just society
- a just claim to the land
- a just punishment
It seems to me that, whenever someone wants to express the same meaning in a predicate, the synonym "fair" is used instead of "just":
- the society is fair
- the claim to the land is fair
- the punishment is fair
Is that right or could I use "just" in the previous 3 examples?
