What are the uses of a pronoun in nominative cases?

Answer 1

A pronoun in the nominative case is used as:

• the subject of a sentence.
• the subject of a clause,
• a predicate nominative (also called a subject complement, a pronoun following a linking verb that restates or stands for the subject).

The nominative pronouns are: I, we, he, she, they, and who.
The pronouns you and it are used as a subject or an object in a sentence.

Example uses:

• We can go to school together. (subject of the sentence)
  
• The car that he drives is very old. (subject of the relative clause)

• You should do what's best for you. (subject of the sentence and object of the preposition 'for')
• The first person to arrive is she. (predicate nominative, restates the subject noun 'person')
• The Browns came to visit and they brought the baby. (subject of the second part of the compound sentence)
• It is raining but the weather report didn't call for it. (subject of the sentence and object of the preposition 'for')

Answer 2

Pronouns in nominative cases are used to identify the subject performing the action in a sentence. They replace nouns to avoid repetition and make sentences clearer and more concise. Common nominative pronouns include "I," "you," "he," "she," "it," "we," and "they."
