Understanding the nuances of English grammar can be challenging, especially when it comes to possessive forms. One common area of confusion is the use of "theirs" versus "their's." These two terms are often misused, leading to grammatical errors that can detract from the clarity and professionalism of written communication. This post aims to clarify the correct usage of "theirs" and "their's," providing examples and explanations to help readers master this aspect of English grammar.
Understanding Possessive Pronouns
Possessive pronouns are words that show ownership or possession. They replace nouns and indicate that something belongs to someone or something. Common possessive pronouns include mine, yours, his, hers, ours, and theirs. These pronouns are used to avoid repetition and make sentences more concise.
The Correct Usage of “Theirs”
“Theirs” is a possessive pronoun that indicates ownership by a group of people or things. It is used to show that something belongs to them. For example:
- “The car is theirs.” (This means the car belongs to them.)
- “The book on the table is theirs.” (This means the book belongs to them.)
It is important to note that “theirs” does not take an apostrophe. The apostrophe is a common mistake that can lead to grammatical errors. The correct form is always “theirs,” without an apostrophe.
The Incorrect Usage of “Their’s”
“Their’s” is a common mistake that arises from the misconception that possessive pronouns should follow the same rules as possessive nouns. However, possessive pronouns do not require an apostrophe. Using “their’s” is grammatically incorrect and should be avoided. For example:
- Incorrect: “The car is their’s.”
- Incorrect: “The book on the table is their’s.”
In both examples, the correct form should be “theirs,” without an apostrophe.
Common Mistakes and How to Avoid Them
One of the most common mistakes is adding an apostrophe to “theirs” to form “their’s.” This error is often made because people confuse possessive pronouns with possessive nouns. Possessive nouns, such as “John’s book” or “the cat’s toy,” require an apostrophe to show ownership. However, possessive pronouns do not follow this rule.
To avoid this mistake, remember that possessive pronouns are already in their possessive form and do not require an apostrophe. Here are some tips to help you remember:
- Possessive pronouns do not take an apostrophe.
- Use “theirs” to indicate ownership by a group of people or things.
- Avoid using “their’s” in any context.
Examples of Correct Usage
To further illustrate the correct usage of “theirs,” let’s look at some examples in different contexts:
- “The house is theirs.” (This means the house belongs to them.)
- “The project is theirs to complete.” (This means they are responsible for completing the project.)
- “The decision is theirs to make.” (This means they have the authority to make the decision.)
In each of these examples, “theirs” is used correctly to indicate ownership or responsibility.
Examples of Incorrect Usage
To highlight the importance of using “theirs” correctly, let’s look at some examples of incorrect usage:
- Incorrect: “The house is their’s.”
- Incorrect: “The project is their’s to complete.”
- Incorrect: “The decision is their’s to make.”
In each of these examples, the use of “their’s” is grammatically incorrect. The correct form should be “theirs” without an apostrophe.
Practical Tips for Mastering Possessive Pronouns
Mastering the use of possessive pronouns can enhance your writing and communication skills. Here are some practical tips to help you remember the correct usage:
- Practice using possessive pronouns in sentences to reinforce the correct form.
- Read widely to see how possessive pronouns are used in different contexts.

By following these tips, you can improve your understanding of possessive pronouns and avoid common mistakes.
📝 Note: Remember that possessive pronouns are already in their possessive form and do not require an apostrophe. Always use "theirs" to indicate ownership by a group of people or things.
In addition to understanding the correct usage of "theirs," it is also important to recognize the differences between possessive pronouns and possessive nouns. Possessive nouns require an apostrophe to show ownership, while possessive pronouns do not. For example:
| Possessive Pronouns | Possessive Nouns |
|---|---|
| mine | John's |
| yours | Mary's |
| his | the dog's |
| hers | the cat's |
| ours | the company's |
| theirs | the students' |
By understanding these differences, you can avoid common grammatical errors and improve the clarity of your writing.
In conclusion, mastering the correct usage of “theirs” versus “their’s” is essential for clear and effective communication. By understanding the rules of possessive pronouns and avoiding common mistakes, you can enhance your writing skills and convey your ideas more effectively. Remember that possessive pronouns do not require an apostrophe, and always use “theirs” to indicate ownership by a group of people or things. With practice and attention to detail, you can master this aspect of English grammar and improve your overall communication skills.
