The red ball is expensive.
The ball is red.
The answer is absolutistic in its nature.
The absolutistic answer that he provided didn't quite fit the given problem.
In the four examples above I can easily place adjectives "red" and "absolutistic" before the noun that they are modifying or right after the verb "is".
However, I can't do that with all adjectives:
The new law is in force as of today.
The in force law gives more freedom to people.
The Constitution is in effect now.
The in effect Constitution must be observed.
My question is: Is it just because these are two-word adjectives or there exist some one-word adjectives that don't boast the same freedom of placement as "red" and "absolutistic"?
Additional question: Is there any grammar term for such adjectives that don't have such freedom?
The Wikipedia page on adjective provides such terms as Prepositive adjectives and Postpositive adjectives, but doesn't seem to provide a term for adjectives that can be both.
