Usually a prepositional phrase would follow the predicate adjective, unless it's in the complete subject and therefore before the verb. Prepositional phrases pop up all over the place though, so I can't say it's impossible. ;) Do you have an example of what you mean?
Excuse me sir , what's the difference between using the verb to Be and other linking verbs in ( S+V + C ) structure or in other words when to use Be and when to use seem / appear / look etc .
I think I understand what you mean, and it's a matter of the definitions of the words. When we use "to be" (am, is, are, was, were, etc.) we are stating that it is absolute, a fact. For "to seem", "to look", and "to appear," those words mean that it might be that way, but we don't know for sure. It seems that way, it looks that way, but you can't say it with certainty. Does that help?
They're basically the same except in the second example you added the infinitive verb "to be." Since "to be" is a linking verb, angry is still the predicate adjective.
