There seem to be two different kinds of adjectives, those that are used as prefixes and those that are used as predicates. Is there a name or terminology for this difference?
The dogs are agressive. Aggressive dogs bark.
This adjective can be used both ways.
The president is alone. The alone president went into his office. <DOES NOT WORK>
The adjective 'alone' can only be used as a predicate.
The only adjectives that seem to not work as a predicate are nouns used as an adjective. For example:
The emergency decree was issued. The situation was highly emergency. <AWKWARD>
