What is the noun that completes sense of subject object or verb?

The noun that completes the sense of a subject, object, or verb is called a complement.

Here's a breakdown:

* Subject Complement: This noun (or pronoun) renames or describes the subject of the sentence. It usually follows a linking verb (e.g., be, seem, become).

* Example: "My sister is a doctor." (Doctor renames the subject "My sister")

* Object Complement: This noun (or pronoun) renames or describes the direct object of the sentence.

* Example: "They elected her president." (President renames the direct object "her")

* Verb Complement: This noun (or pronoun) completes the meaning of a verb. It is often required by a particular verb to make sense.

* Example: "I need a new car." (New car completes the meaning of the verb "need")

Important Note: While noun complements are common, other parts of speech like adjectives, adverbs, and prepositional phrases can also act as complements depending on the structure of the sentence.
