What does the addition of the infinitive do in this sentence? I appear to be fortunate. I appear fortunate is a linking verb and predicate adjective. is it proper to use infinitive here? Does it affect the predicate adjective? I am confused about whether adding the infinitive to be after a linking verb is correct.
I would appear to be (a very) fortunate (person).
No, it doesn't affect the adjective.
You can't use is after every linking verb.
You can use it after: seem, prove, come, get, look ...
You seem to be sick
It might prove to be wrong.
How did you come to be so dirty?
How did he get to be a teacher?
You look to be in pain.
(Note that a lot of these need "to be").
You can't use it after: become, remain, stay ...
