It occurs me that in such sentences as
He is far from happy.
However, just as the critics are not of one mind in their criticism, so they are far from united on what to do.
the preposition from is followed by adjectives. Since prepositions by definition are placed before nouns/noun phrases, I wonder if far from is a unique case. Are there other similar cases? I can't think of any.
Is this simply an omission of being? Does this omission occur with other prepositions?
