The verb 'seem' is a specimen linking verb, as in:
(1) He seems a nice guy.
But it can have a clause as its complement, as in:
(2) He seems to be a nice guy. [to-infinitive clause]
(3) It seems that he is a nice guy. [that-clause]
In (2) or (3) or both, is the verb 'seem' still a linking verb or something else?
Answers to another question, don't specifically say whether the verb 'seem' as in (2) or (3) can be classified as a linking verb or not.
