Possessive adjectives are an essential part of English grammar. Words such as my, your, his, her, its, our, and their are used frequently to show who owns or is associated with a person, object, or thing. However, many learners still confuse possessive adjectives with possessive pronouns, especially when completing grammar exercises or writing sentences.
To remember these forms more effectively, it is helpful to combine grammar study with regular practice. Possessive adjectives exercises help learners recognise the correct form of each word, identify the owner in a sentence, and avoid common grammatical mistakes.
In this article, you will practise several types of exercises, from basic fill-in-the-blank activities to error correction, multiple-choice questions, sentence rewriting, and mixed exercises. Each activity includes answers and explanations to help you check your understanding and improve your English grammar skills.
A Quick Review of Possessive Adjectives
Before starting the exercises, review the possessive adjectives commonly used in English.
| Subject pronoun | Possessive adjective | Meaning |
| I | my | Belonging to me |
| You | your | Belonging to you |
| He | his | Belonging to him |
| She | her | Belonging to her |
| It | its | Belonging to it |
| We | our | Belonging to us |
| They | their | Belonging to them |
A possessive adjective comes before a noun to show who owns something or who it is associated with.
Examples:
- This is my book.
- She loves her family.
- They are cleaning their room.
- The dog is wagging its tail.
There are three important rules to remember:
- Possessive adjectives are used with nouns, such as my bag, his car, and their house.
- The choice of possessive adjective depends on the owner, not on whether the noun that follows is singular or plural.
- Possessive adjectives are different from possessive pronouns. For example, my usually comes before a noun, while mine can stand alone and replace the phrase my book.

Possessive Adjectives Exercises: Basic to Advanced

Exercise: Find and Correct the Mistakes
A common mistake when learning possessive adjectives is using a subject pronoun or possessive pronoun instead of a possessive adjective. Identify the incorrect word in each sentence and replace it with the correct form.
Exercise 3: Correct the sentences
- He loves she mother.
- They lost them keys.
- I finished mine homework.
- We visited us teacher.
- He likes he dog.
- The cat cleaned it paws.
- Anna called she friend yesterday.
- We forgot we bags at school.
Answers and explanations
- she → her: Use her before the noun mother.
- them → their: Their shows possession of the keys.
- mine → my: Mine is a possessive pronoun and does not come directly before the noun homework.
- us → our: Use our before the noun teacher.
- he → his: His is the possessive adjective corresponding to he.
- it → its: Use its to show that the paws belong to the cat.
- she → her: Use her before the noun friend.
- we → our: Our is the possessive adjective corresponding to we.
A useful tip is to remember that he, she, they, and we are subject pronouns, while his, her, their, and our can function as possessive adjectives before nouns. Always consider the word’s function in the sentence instead of choosing a form based only on how it looks.
Exercise: Distinguish Possessive Adjectives from Possessive Pronouns
Possessive adjectives and possessive pronouns both express ownership, but they have different grammatical functions. A possessive adjective needs a noun after it, whereas a possessive pronoun can stand alone and replace a noun phrase.
For example:
- This is my book. (My comes before the noun book.)
- This book is mine. (Mine replaces the phrase my book.)
Exercise 4: Choose the correct answer
- This is ____ book. (my / mine)
- The blue car is ____. (her / hers)
- That house is ____. (their / theirs)
- I like ____ idea. (your / yours)
- This dog is ____. (our / ours)
- Is this ____ pen? (your / yours)
- The red bag is ____. (my / mine)
- They forgot ____ homework. (their / theirs)
- This is ____ room. (our / ours)
- The choice is ____. (his / he)
Answers and explanations
- my — It comes before the noun book.
- hers — It stands alone and replaces her car.
- theirs — It replaces the phrase their house.
- your — It comes before the noun idea.
- ours — It stands alone and replaces our dog.
- your — It comes before the noun pen.
- mine — It stands alone and replaces my bag.
- their — It comes before the noun homework.
- our — It comes before the noun room.
- his — His can function as a possessive pronoun when it stands alone.
Remember that his can function as both a possessive adjective and a possessive pronoun. Its grammatical role depends on how it is used in the sentence.

Tips for Getting Possessive Adjectives Exercises Right
To improve your results when completing possessive adjectives exercises, focus on the following principles.
- Identify the owner: Determine who owns the object or is associated with the thing before choosing an answer.
- Distinguish possessive adjectives from possessive pronouns: My book is correct because my comes before a noun, while This book is mine is correct because mine stands alone.
- Do not confuse “its” and “it’s”: Its expresses possession, whereas it’s is a contraction of it is or it has.
- Pay attention to the subject: Possessive adjectives depend on the owner, not on whether the following noun is singular or plural.
- Read the whole sentence: Some sentences may allow different answers depending on the owner or situation. Use the context to select the most appropriate option.
After completing each exercise, review your incorrect answers and practise those forms again. Once you understand the basic rules, try writing your own sentences about family, school, work, and everyday objects. This will help you apply possessive adjectives naturally in both speaking and writing.
For more detailed grammar guidance, you can also review a lesson on possessive adjectives to reinforce the rules and understand how these words differ from related grammatical forms before moving on to more challenging activities.
Frequently Asked Questions About Possessive Adjectives
Do possessive adjectives change according to whether a noun is singular or plural?
No. Possessive adjectives do not change according to the number of the noun that follows them.
Examples:
- my book
- my books
In both examples, my stays the same because the owner is I.
What is the difference between “its” and “it’s”?
Although these words look similar, they have different grammatical functions.
- Its: A possessive adjective used before a noun. Example: The dog wagged its tail.
- It’s: A contraction of it is or it has. Example: It’s raining today.
A quick way to check is to replace it’s with it is or it has. If the sentence no longer makes sense or becomes grammatically incorrect, you may need its instead.
Can “their” refer to one person?
Yes. In modern English, their can refer to one person when their gender is unknown or when the speaker does not want to specify it.
Examples:
- Someone left their phone on the table.
- Each student must bring their ID card to the exam.
This usage is common in contemporary English and allows speakers to use gender-neutral language naturally.
When should “its” be used for animals?
Its is commonly used when referring to an animal without emphasising its gender.
Examples:
- The cat cleaned its paws.
- The dog wagged its tail happily.
If the speaker knows the animal’s gender or wants to express a personal connection with a pet, his or her may also be used.
For example: My dog loves his toy.
Can a possessive adjective be used without a noun?
Generally, no. A possessive adjective needs a noun to form a complete noun phrase.
Examples:
- my car
- her house
If you want to express ownership without repeating the noun, use a possessive pronoun instead.
Examples:
- This car is mine.
- That house is hers.
