Final answer:
The second noun in a N-LV-N sentence construction is referred to as the predicate nominative. It is a noun or pronoun that follows a linking verb and renames or identifies the subject, making both terms identical in grammatical terms. A predicate nominative should not be confused with a direct object which follows a transitive action verb.
Step-by-step explanation:
In a N-LV-N sentence construction, the second noun after the linking verb (LV) is often referred to as the predicate nominative. The predicate nominative, which completes the meaning of the subject, is a noun or pronoun that follows a linking verb and renames or identifies the subject. It mirrors, or refers to, the subject, making both terms identical in grammatical terms.
For instance, in the sentence 'John is a teacher', 'John' is the subject, 'is' is the linking verb, and 'a teacher' is the predicate nominative. Here, 'a teacher' gives more information about 'John', linking back to him as its noun or antecedent, and establishing agreement between the subject and the verb.
Note that a predicate nominative should not be confused with a direct object, which follows a transitive action verb, not a linking verb. Also, remember that consistency in number between the subject and verb (singular with singular, plural with plural) is an essential aspect of proper English sentence construction.
