Sentence 006 Let the cat out of the bag.
Leslie: What is the second part of the Sentence: ’a great English physicist in the 17th and 18th centuries’? Part of the Verb?
Enci: No, no. It can’t be. There is neither a Verbal nor an Extension of a Verb in it.
L: Do you think it is a Verb Complement?
E: No, it can’t be a VC either. The Verb Complement is an Infinitive or Gerund.
L: Do you think it is one unit, like the Predicate?
E: I don’t think so. ’In the 17th and 18th centuries’ is most definitely an Adverb of Time and a Time Marker.
L: You’re right. Can ’a great English physicist’ be the Object in the Sentence?
E: I don’t think so. ’Was’ is an Intransitive Verb here and as such it cannot have an Object.
L: You are right again here. ’Was’ is actually a Copula, a Linking Verb which is a linguistic equation sign [ = ]. It links the two parts of the Subject together.
E: Then ’a great English physicist’ must be the Extension of the Subject. Is it the Extension of the Subject, or a Subject Complement?
L: They are practically the same, both meaning ’a part of the Sentence that makes the Subject complete’.
