One of the most common mistakes English learners—and even native speakers—make is confusing their, there, and they're.

These three words sound exactly the same when spoken, but they have completely different meanings and grammar rules.

Learning the difference will improve your writing, speaking, and confidence in English.

Why Are These Words Confusing?

These words are called homophones.

Homophones are words that:

• Sound the same
• Have different meanings
• Have different spellings

Understanding the context is the key to choosing the correct word.

What Does "Their" Mean?

Their is a possessive adjective.
It shows that something belongs to someone.

Structure

Their + noun

Examples

• Their house is very large.
• I like their new car.
• Their teacher is friendly.
• The students forgot their books.

In each sentence, their shows ownership.

Remember

Their = Belongs to them

What Does "There" Mean?

There usually refers to:

• A place
• A location
• The existence of something

Examples (Location)

• The restaurant is over there.
• Put your bag there.
• My friends are waiting there.

Examples (Existence)

• There is a book on the table.
• There are many students in the classroom.
• There was a problem yesterday.

Remember

There = Place or existence

What Does "They're" Mean?

They're is a contraction.
It means: They are

Examples

• They're studying English.
• They're my best friends.
• They're going to travel tomorrow.
• I think they're ready.

Test

Replace they're with they are.
If the sentence still makes sense, they're is correct.
Example:
They're happy.
↓
They are happy.

Common Mistakes

  ✅ There is a restaurant near my house.

• ❌ Their going to the airport.

Common Writing Tips

Before writing, ask yourself:

• Does it show ownership? Use their. (Example: Their teacher)
• Is it talking about a place? Use there. (Example: The bus is there.)
• Can you replace it with "they are"? Use they're. (Example: They're excited. ↓ They are excited.)
