What are the differences between nominative, accusative, and genitive pronouns?

Nominative, accusative, and genitive pronouns are different forms of pronouns that serve different grammatical functions in a sentence. Let's explore the differences between these pronoun cases:

1. Nominative Pronouns:
Nominative pronouns are used as the subject of a sentence or clause. They typically answer the question "Who?" or "What?" and perform the action in the sentence. Examples of nominative pronouns include "I," "you," "he," "she," "it," "we," and "they." Nominative pronouns are used when the pronoun is the subject of the sentence or when it follows a linking verb.

Example sentences:
- She is a talented singer.
- We are going to the park.

2. Accusative Pronouns:
Accusative pronouns, also known as objective pronouns, are used as the direct object, indirect object, or object of a preposition in a sentence. They typically answer the questions "Whom?" or "What?" Examples of accusative pronouns include "me," "you," "him," "her," "it," "us," and "them." Accusative pronouns are used when the pronoun receives the action of the verb or when it is the object of a preposition.

Example sentences:
- John gave me a book. (me is the indirect object)
- She saw him at the party. (him is the direct object)
- The cat jumped over it. (it is the object of the preposition)

3. Genitive Pronouns:
Genitive pronouns, also known as possessive pronouns, indicate ownership or possession. They are used to show that something belongs to someone or something. Examples of genitive pronouns include "mine," "yours," "his," "hers," "its," "ours," and "theirs." Genitive pronouns can be used to replace possessive nouns or to show ownership without using a noun.

Example sentences:
- This book is mine.
- Is this pen yours?
- The house is theirs.

In summary, nominative pronouns are used as the subject of a sentence, accusative pronouns are used as objects, and genitive pronouns indicate possession. Understanding the differences between these pronoun cases is essential for proper sentence construction and effective communication.
