Case: Definition, Types, Examples and Exercises

A noun does not work alone in a sentence. It has a relationship with the verb and other words in the sentence. This relationship is called its case.

Understanding the case of a noun helps us identify its role in a sentence, such as whether it is the subject, object, owner, receiver, or person being addressed.

What is Case?

Read the following sentences.

• Sachin bought a car.
• She goes to school.

In the first sentence:

• Sachin is the person who performs the action.
• Car is the thing affected by the action.

In the second sentence:

• She performs the action.
• School tells us where she goes.

Each noun or pronoun has a different relationship with the verb.

Definition

Case is the grammatical form or function of a noun or pronoun that shows its relationship with other words, especially the verb, in a sentence.

Types of Cases

In traditional English grammar, there are five cases.

1. Nominative Case
2. Objective (Accusative) Case
3. Possessive (Genitive) Case
4. Dative Case
5. Vocative Case

1. Nominative Case

A noun or pronoun used as the subject of a verb is said to be in the Nominative Case.

Definition

When a noun or pronoun performs the action of the verb or is the subject of the sentence, it is in the Nominative Case.

Examples

• Kiran has many toys.
• They are singing.
• The shirt is black.
• My father works in a bank.

In these sentences, Kiran, They, The shirt, and My father are the subjects.

How to Identify the Nominative Case

Ask Who? or What? before the verb.

2. Objective (Accusative) Case

A noun or pronoun used as the object of a verb is said to be in the Objective (Accusative) Case.

Definition

When a noun or pronoun receives the action of a verb, it is in the Objective (Accusative) Case.

Examples

• The girl ate a chocolate.
• Sarita watched the movie.
• The President met us.
• Rahul kicked the ball.

The words chocolate, movie, us, and ball are the objects of the verbs.

How to Identify the Objective Case

Ask What? or Whom? after the verb.

3. Possessive (Genitive) Case

The Possessive Case shows ownership, possession, or a close relationship between two nouns.

Definition

When a noun shows ownership or possession, it is said to be in the Possessive (Genitive) Case.

Examples

• Abdul’s pencil
• The teacher’s bag
• Riya’s notebook

Here, the nouns Abdul, teacher, and Riya show ownership.

Rules for Forming the Possessive Case

Rule 1: Singular Nouns

Add ‘s to a singular noun.

Examples:

• Rahul’s bicycle is new.
• The Queen’s crown was made of gold.

Rule 2: Regular Plural Nouns Ending in -s

Add only an apostrophe (‘).

Examples:

• The students’ classroom is clean.
• The boys’ hostel is nearby.

Rule 3: Irregular Plural Nouns

If the plural noun does not end in -s, add ‘s.

Examples:

• Children’s Park
• Women’s College
• Men’s Cricket Team

Rule 4: Possession of Non-living Things

Generally, of is preferred instead of ‘s for non-living things.

✔ The legs of the table.

✔ The roof of the house.

❌ The table’s legs. (Less common in traditional grammar.)

Modern English Note: Both forms are acceptable in many contexts. For example, the company’s policy, the world’s population, and today’s weather are perfectly correct.

Rule 5: Joint Possession

When two or more people own the same thing, add ‘s only to the last noun.

Examples:

• Mohan and Sohan’s house
• Ali and Ahmed’s shop

Both people share one house or one shop.

Rule 6: Separate Possession

When each person owns something separately, add ‘s to each noun.

Examples:

• Sachin’s and Virat’s bats
• Riya’s and Priya’s bags

Each person owns a different object.

Rule 7: Compound Nouns

Add ‘s to the last word of a compound noun.

Examples:

• My father-in-law’s car
• My sister-in-law’s house
• The commander-in-chief’s office

4. Dative Case

The Dative Case indicates the indirect object or the recipient of an action.

Definition

A noun or pronoun that shows to whom or for whom something is given, sent, or done is in the Dative Case.

Examples

• My friend gave Radha an English book.
• Kavita wrote a letter to her father.
• The teacher gave the students homework.

In these sentences:

• Radha
• her father
• the students

receive the action.

How to Identify the Dative Case

Ask:

• To whom?
• For whom?

after the verb.

5. Vocative Case

The Vocative Case is used when directly addressing someone.

Definition

A noun used to address a person, animal, or group directly is said to be in the Vocative Case.

Examples

• Tommy, where did you find this diary?
• Goodbye, Kezia.
• Pranjal, please help me.
• Friends, let us begin today’s lesson.

The words Tommy, Kezia, Pranjal, and Friends are in the Vocative Case.
