Pronouns can change form depending on how they are used in a sentence. For example, we say “I called her,” not “Me called she.” These different forms are known as cases of pronouns.
In English, there are three main pronoun cases: subjective, objective, and possessive. The subjective case is used for the subject of a sentence, the objective case is used for the object of a verb or preposition, and the possessive case shows ownership or belonging.
Understanding pronoun cases helps you choose correctly between words such as I and me, he and him, she and her, and they and them.
In this guide, you will learn the three cases of pronouns, their rules and examples, and how to avoid common pronoun case mistakes.

What Are Pronoun Cases?
Pronoun cases are the different forms that pronouns take depending on their grammatical role in a sentence. A pronoun may act as the subject, the object, or show possession, and its form can change accordingly.
For example:
- She called me.
- I called her.
- The book is hers.
In these sentences, she, her, and hers refer to the same person, but each pronoun has a different form because it performs a different grammatical function.
English has three main cases of pronouns:
- Subjective case (nominative case): used when the pronoun is the subject of a verb.
- Objective case: used when the pronoun is the object of a verb or preposition.
- Possessive case: used to show ownership or belonging.
Consider another example:
- He gave me his notebook.
Here, he is in the subjective case because it performs the action. Me is in the objective case because it receives the action, while his shows possession.
Understanding these three cases makes it easier to choose the correct forms of pronouns, especially commonly confused pairs such as I/me, he/him, she/her, we/us, and they/them.
Three Main Cases of Pronouns in English
English has three main cases of pronouns: subjective, objective, and possessive. The case you use depends on the role the pronoun performs in a sentence.
For example, the pronoun referring to a male person may appear as he, him, or his:
-
He called Sarah. — Subjective case
-
Sarah called him. — Objective case
-
The book is his. — Possessive case
Although these pronouns refer to the same person, their forms change according to their grammatical function.
1. Subjective Case Pronouns
Subjective case pronouns, also called subject pronouns or nominative pronouns, are used when a pronoun acts as the subject of a verb. In other words, the pronoun usually represents the person or thing performing the action or being described.
The subjective case pronouns are:
I, you, he, she, it, we, they
Examples of Subjective Pronouns
-
I enjoy reading English books.
-
You speak English very well.
-
He works at a local company.
-
She is learning English.
-
It looks beautiful.
-
We study together every evening.
-
They are playing football in the park.
In each sentence, the bold pronoun functions as the subject.
Subjective Pronouns with Compound Subjects
Subjective pronouns are also used when the subject contains more than one person:
-
Sarah and I are classmates.
-
He and I work together.
-
You and she can complete the project.
A common mistake is using me instead of I in a compound subject:
-
❌ Me and Sarah went to the library.
-
✅ Sarah and I went to the library.
An easy way to check is to remove the other person’s name:
-
❌ Me went to the library.
-
✅ I went to the library.
Because I went is correct, Sarah and I went to the library is also correct.
2. Objective Case Pronouns
Objective case pronouns, commonly called object pronouns, are used when a pronoun functions as the object of a verb or a preposition.
The objective case pronouns are:
me, you, him, her, it, us, them
Object of a Verb
When a pronoun receives the action of a verb, use the objective case.
-
Sarah called me yesterday.
-
I invited him to the party.
-
The teacher helped us with the lesson.
-
We saw them at the station.
-
She knows you very well.
For example:
The teacher helped us.
Here, the teacher performs the action, while us receives the action. Therefore, us is in the objective case.
Object of a Preposition
Use an objective pronoun after prepositions such as to, for, with, from, at, about, and between.
-
Please give the book to me.
-
This gift is for her.
-
John went to the store with him.
-
The teacher spoke to us after class.
-
Keep this information between you and me.
A common error is using a subjective pronoun after a preposition:
-
❌ This gift is for she.
-
✅ This gift is for her.
-
❌ The teacher spoke to we.
-
✅ The teacher spoke to us.
Objective Pronouns in Compound Objects
When two or more people are objects in a sentence, the pronoun should still be in the objective case.
-
The teacher praised Sarah and me.
-
She invited John and him to dinner.
-
The manager spoke to Ali and us.
A common mistake is using I simply because another person’s name appears with the pronoun:
-
❌ The teacher praised Sarah and I.
-
✅ The teacher praised Sarah and me.
To check which pronoun is correct, remove the other person’s name:
-
❌ The teacher praised I.
-
✅ The teacher praised me.
Therefore, “The teacher praised Sarah and me” is correct.
This same test can help you choose correctly between I and me in many sentences.
3. Possessive Case Pronouns
The possessive case is used to show ownership, possession, or a relationship between someone or something and another noun.
English uses two related sets of possessive forms:
-
Possessive determiners: my, your, his, her, its, our, their
-
Possessive pronouns: mine, yours, his, hers, ours, theirs
Although both forms express possession, they are used differently in sentences.
Possessive Determiners
Possessive determiners come before a noun. They tell us who or what the noun belongs to.
-
This is my book.
-
Is that your phone?
-
She forgot her keys.
-
We finished our homework.
-
They sold their house.
A possessive determiner normally cannot stand alone because it modifies a noun.
For example:
-
✅ This is my book.
-
❌ This book is my.
Possessive Pronouns
Possessive pronouns can stand alone and replace a noun phrase that has already been mentioned or is understood from the context.
-
This book is mine.
-
That jacket is yours.
-
The blue bag is hers.
-
This classroom is ours.
-
Those bicycles are theirs.
Compare these two forms:
-
This is my laptop.
-
This laptop is mine.
Both sentences show possession, but my appears before the noun laptop, while mine stands alone.
Similarly:
-
That is her bag.
-
That bag is hers.
Both sentences are correct. The difference is grammatical structure, not meaning.
Possessive Forms Chart
| Subject Pronoun | Possessive Determiner | Possessive Pronoun |
|---|---|---|
| I | my | mine |
| you | your | yours |
| he | his | his |
| she | her | hers |
| it | its | — |
| we | our | ours |
| they | their | theirs |
Notice that English does not normally use an independent possessive pronoun corresponding to its. We use its before a noun:
-
The dog wagged its tail.
Also remember that its and it’s have different meanings:
-
its = possessive form
-
it’s = contraction of it is or it has
For example:
-
The company changed its policy.
-
It’s a new policy.
Pronoun Cases Chart
The following chart compares the subjective, objective, and possessive cases of personal pronouns. Use it as a quick reference when deciding which pronoun form is correct in a sentence.
| Person | Subjective Case | Objective Case | Possessive Determiner | Possessive Pronoun |
|---|---|---|---|---|
| 1st person singular | I | me | my | mine |
| 2nd person singular/plural | you | you | your | yours |
| 3rd person singular (male) | he | him | his | his |
| 3rd person singular (female) | she | her | her | hers |
| 3rd person singular (thing/animal) | it | it | its | — |
| 1st person plural | we | us | our | ours |
| 3rd person plural | they | them | their | theirs |
How to Read the Pronoun Case Chart
The form of a pronoun changes according to its function in the sentence. For example, consider the first-person singular forms:
-
I am learning English. — subjective case
-
The teacher helped me. — objective case
-
This is my notebook. — possessive determiner
-
This notebook is mine. — possessive pronoun
The same pattern can be seen with other pronouns:
-
She invited us. → We invited her.
-
They called me. → I called them.
-
This is their classroom. → The classroom is theirs.
A simple way to remember the three cases is:
Subjective = Who performs or experiences?
Objective = Whom does the verb or preposition affect?
Possessive = Whose is it?
How to Choose the Correct Pronoun Case
Choosing the correct pronoun case becomes easier when you first identify the pronoun’s role in the sentence. Ask whether the pronoun is acting as a subject, an object, or showing possession.
1. Use the Subjective Case for Subjects
Use a subjective pronoun when it functions as the subject of a verb.
-
I work from home.
-
She speaks English fluently.
-
They arrived early.
-
We are ready to begin.
Compare:
-
❌ Me went to the store.
-
✅ I went to the store.
Because the pronoun performs the action, the subjective form I is required.
2. Use the Objective Case for Objects of Verbs
Use an objective pronoun when it receives the action of a verb.
-
Sarah called me.
-
We invited him.
-
The teacher helped her.
-
I saw them yesterday.
Compare:
-
❌ Sarah called I.
-
✅ Sarah called me.
Here, Sarah is the subject performing the action, while me is the object receiving it.
3. Use the Objective Case After Prepositions
Pronouns that are objects of prepositions normally take the objective form.
Common prepositions include to, for, with, from, about, between, at, and without.
-
She gave the book to me.
-
I went with him.
-
This message is for her.
-
The teacher spoke to us.
-
Keep this between you and me.
Compare:
-
❌ between you and I
-
✅ between you and me
Because the pronoun follows the preposition between, the objective form me is correct.
4. Use the Possessive Case to Show Ownership
Use possessive forms when you want to show that something belongs to or is associated with someone or something.
Use a possessive determiner before a noun:
-
This is my book.
-
She forgot her phone.
-
They sold their house.
Use an independent possessive pronoun when the noun does not follow:
-
This book is mine.
-
The phone is hers.
-
The house is theirs.
Compare:
-
This is our classroom.
-
This classroom is ours.
5. Be Careful with Compound Subjects and Objects
Pronoun case can be more difficult when another person’s name is included.
Use the subjective case when the pronoun is part of the subject:
-
Sarah and I went shopping.
-
He and I are classmates.
Use the objective case when the pronoun is part of the object:
-
The teacher helped Sarah and me.
-
She invited John and him.
A useful test is to temporarily remove the other person’s name.
For example:
Sarah and I went shopping.
Remove Sarah and:
I went shopping. ✅
Now consider:
The teacher helped Sarah and me.
Remove Sarah and:
The teacher helped me. ✅
This simple test can help you decide whether I or me is correct in many everyday sentences.
Quick Rule to Remember
When you are unsure which pronoun case to use, identify its job:
-
Subject → subjective case: I, you, he, she, it, we, they
-
Object → objective case: me, you, him, her, it, us, them
-
Possession → possessive form: my/mine, your/yours, his, her/hers, its, our/ours, their/theirs
The grammatical role of the pronoun—not its position alone—determines which form you should use.
Common Pronoun Case Errors
Pronoun case errors often occur when speakers choose between forms such as I and me, he and him, she and her, we and us, or they and them. These mistakes are especially common when a sentence contains two people.
Here are some of the most common pronoun case mistakes and how to correct them.
I vs. Me
Use I as a subject and me as an object.
-
❌ Me went to the library.
-
✅ I went to the library.
-
❌ The teacher called I.
-
✅ The teacher called me.
The same rule applies when another person is included:
-
❌ Me and Sarah are classmates.
-
✅ Sarah and I are classmates.
-
❌ The teacher helped Sarah and I.
-
✅ The teacher helped Sarah and me.
To check, remove the other person’s name: I am a classmate and the teacher helped me are correct.
He vs. Him
Use he when the pronoun is the subject and him when it is an object.
-
❌ Him plays football every weekend.
-
✅ He plays football every weekend.
-
❌ I spoke to he yesterday.
-
✅ I spoke to him yesterday.
She vs. Her
Use she as a subject and her as an object.
-
❌ Her works at the hospital.
-
✅ She works at the hospital.
-
❌ I gave the book to she.
-
✅ I gave the book to her.
Remember that her can also function as a possessive determiner:
-
I called her. — object pronoun
-
That is her book. — possessive determiner
We vs. Us
Use we as a subject and us as an object.
-
❌ Us are studying English.
-
✅ We are studying English.
-
❌ The teacher gave we more time.
-
✅ The teacher gave us more time.
This rule also applies after prepositions:
-
❌ She came with we.
-
✅ She came with us.
They vs. Them
Use they as a subject and them as an object.
-
❌ Them live next door.
-
✅ They live next door.
-
❌ I spoke to they after class.
-
✅ I spoke to them after class.
You and I vs. You and Me
Both expressions can be correct. The correct choice depends on the pronoun’s role in the sentence.
Use you and I when the expression is the subject:
-
You and I need to talk.
-
You and I are responsible for the project.
Use you and me when the expression is the object:
-
She invited you and me.
-
This conversation is between you and me.
Therefore, the common expression “between you and I” is grammatically incorrect in standard English because between is a preposition and requires the objective form me.
Don’t Choose a Pronoun Just Because It Sounds More Formal
Some speakers use I instead of me because they think I sounds more formal or grammatically correct. However, pronoun choice depends on grammatical function, not formality.
For example:
-
❌ Please send the document to Sarah and I.
-
✅ Please send the document to Sarah and me.
Remove Sarah and to test the sentence:
-
❌ Please send the document to I.
-
✅ Please send the document to me.
If the sentence works with me when the other name is removed, use me in the compound expression as well.
Examples of Pronoun Cases in Sentences
The following examples show how subjective, objective, and possessive pronouns are used in everyday English sentences.
Subjective Case Examples
In these sentences, the pronoun functions as the subject:
-
I study English every day.
-
You are very helpful.
-
He works in an office.
-
She enjoys reading novels.
-
It needs to be repaired.
-
We went to the mall yesterday.
-
They arrived before noon.
Objective Case Examples
In these sentences, the pronoun functions as the object of a verb or preposition:
-
Sarah called me yesterday.
-
I will help you with your homework.
-
We met him at the station.
-
The manager spoke to her.
-
Please give it to John.
-
The teacher gave us extra time.
-
I went to the movies with them.
Possessive Case Examples
These sentences use possessive forms to show ownership or belonging:
-
This is my notebook.
-
This notebook is mine.
-
Is that your jacket?
-
The jacket is yours.
-
She left her phone at home.
-
The phone on the table is hers.
-
We finished our project.
-
The final decision is ours.
-
They brought their children.
-
Those seats are theirs.
Compare the Three Pronoun Cases
Looking at the same person across different sentences makes the differences easier to see:
First person:
-
I bought a new laptop. — Subjective
-
Sarah helped me choose it. — Objective
-
The laptop is mine. — Possessive
Third person masculine:
-
He called yesterday. — Subjective
-
I spoke to him this morning. — Objective
-
The blue car is his. — Possessive
Third person feminine:
-
She joined the class. — Subjective
-
The teacher welcomed her. — Objective
-
The red notebook is hers. — Possessive
First person plural:
-
We completed the project. — Subjective
-
The manager thanked us. — Objective
-
The final presentation is ours. — Possessive
Third person plural:
-
They live next door. — Subjective
-
I spoke to them yesterday. — Objective
-
The bicycles outside are theirs. — Possessive
These examples show that the correct pronoun form depends on the grammatical role it performs in the sentence.

Conclusion
Understanding the cases of pronouns helps you choose the correct pronoun form based on its role in a sentence. English has three main pronoun cases: subjective, objective, and possessive.
Use subjective pronouns such as I, he, she, we, and they as subjects. Use objective pronouns such as me, him, her, us, and them as objects of verbs and prepositions. Use possessive forms such as my/mine, your/yours, her/hers, our/ours, and their/theirs to show ownership or belonging.
When you are unsure which form to use, identify the pronoun’s job in the sentence. Ask yourself: Is it the subject, an object, or showing possession? This simple check can help you avoid common mistakes such as me and Sarah, between you and I, and this book is her.
Continue practicing these forms in everyday sentences, and choosing the correct pronoun case will become much easier.

Frequently Asked Questions About Pronoun Cases
What are the three cases of pronouns?
The three main cases of pronouns in English are the subjective case, objective case, and possessive case. The subjective case is used for subjects, the objective case for objects, and the possessive case to show ownership or belonging.
What is the subjective case of a pronoun?
The subjective case is used when a pronoun functions as the subject of a verb. Subjective pronouns include I, you, he, she, it, we, and they.
For example:
-
She speaks English.
-
They live nearby.
What is the objective case of a pronoun?
The objective case is used when a pronoun functions as the object of a verb or preposition. Objective pronouns include me, you, him, her, it, us, and them.
For example:
-
Sarah called me.
-
I spoke to him.
What is the possessive case of a pronoun?
The possessive case shows ownership or belonging. Possessive forms include my/mine, your/yours, his, her/hers, its, our/ours, and their/theirs.
For example:
-
This is my book.
-
This book is mine.
What is the difference between subjective and objective pronouns?
A subjective pronoun normally functions as the subject of a verb, while an objective pronoun functions as the object of a verb or preposition.
Compare:
-
She called John. — subjective
-
John called her. — objective
Similarly:
-
They helped us.
-
We helped them.
Is “between you and I” correct?
No. In standard English, “between you and me” is correct because between is a preposition, and pronouns used as objects of prepositions take the objective case.
-
❌ between you and I
-
✅ between you and me
Is it “Sarah and I” or “Sarah and me”?
Both can be correct depending on their grammatical role.
Use Sarah and I as the subject:
-
Sarah and I went shopping.
Use Sarah and me as the object:
-
The teacher helped Sarah and me.
A useful test is to remove Sarah and. You would say I went shopping but the teacher helped me.
What is the difference between “my” and “mine”?
Both forms show possession, but they are used differently.
My comes before a noun:
-
This is my book.
Mine stands alone:
-
This book is mine.
The same pattern applies to your/yours, her/hers, our/ours, and their/theirs.
Why are pronoun cases important?
Pronoun cases help show the grammatical relationship between words in a sentence. Using the correct case makes sentences clearer and helps you avoid common errors involving forms such as I/me, he/him, she/her, we/us, and they/them.
