Simple Background Explanation
English has many words that sound alike but have different meanings. These are called homophones.
Words like:
- their
- there
- they’re
- theirs
- there’s
often confuse learners because they sound very similar.
The confusion between theirs and theres usually happens because:
- people type quickly
- apostrophes are forgotten
- pronunciation sounds close
- autocorrect changes words
Understanding the small differences can make your writing much clearer.
What Does “Theirs” Mean?
Theirs is a possessive pronoun.
It shows that something belongs to “them.”
Examples
- That house is theirs.
- The final decision was theirs.
- These bags are theirs, not ours.
- The victory was theirs after a long game.
Easy Way to Remember
“Theirs” answers the question:
“Whose is it?”
If the answer is “belongs to them,” then use theirs.
What Does “Theres” Mean?
Theres without an apostrophe is usually considered incorrect in standard English.
Most of the time, the writer actually means:
There’s
“There’s” is the short form of:
- there is
- there has
Examples
- There’s a problem here.
- There’s a new student in class.
- There’s been a mistake.
Without the apostrophe, theres is normally a spelling mistake.
The Difference Between Theirs and There’s
This is the most important part to understand.
Theirs = Ownership
Use it when something belongs to people.
Examples
- The books are theirs.
- That seat is theirs.
- The idea was theirs.
There’s = “There is” or “There has”
Use it when introducing something or talking about existence.
Examples
- There’s a bird on the roof.
- There’s some milk in the fridge.
- There’s been an accident nearby.
Easy Comparison Table
| Word | Meaning | Type | Example |
| theirs | belongs to them | possessive pronoun | The jackets are theirs. |
| there’s | there is / there has | contraction | There’s a dog outside. |
| theres | usually incorrect | spelling mistake | ❌ Theres a problem. |
Which One Should You Use?
Use “Theirs” When Talking About Ownership
Choose theirs if something belongs to a group of people.
Examples
- The classroom is theirs now.
- Those shoes are theirs.
- The responsibility is theirs.
Helpful Test
Replace the word with:
- ours
- yours
- mine
If the sentence still makes sense, theirs is probably correct.
Example:
- The car is theirs.
- The car is ours.
Both work correctly.
Use “There’s” When Meaning “There Is”
Choose there’s when talking about something existing or being present.
Examples
- There’s a message for you.
- There’s food on the table.
- There’s still time left.
Helpful Test
Replace “there’s” with “there is.”
Example:
- There’s a problem.
- There is a problem.
Both mean the same thing.
Common Mistakes People Make
1. Forgetting the Apostrophe
Many people write:
- ❌ Theres a meeting today.
Correct form:
- ✅ There’s a meeting today.
The apostrophe is important because it shows the shortened form of “there is.”
2. Using “Theirs” Instead of “There’s”
Incorrect:
- ❌ Theirs a dog outside.
Correct:
- ✅ There’s a dog outside.
Why? Because the sentence means “there is.”
3. Using “There’s” for Ownership
Incorrect:
- ❌ The bags are there’s.
Correct:
- ✅ The bags are theirs.
Remember:
- ownership = theirs
- existence = there’s
4. Mixing Up Similar Words
Many learners also confuse:
- their
- there
- they’re
- theirs
- there’s
