Their shows ownership, while they’re is a short form of they are. “Their car is new” means the car belongs to them, while “They’re happy” means they are happy.
A student once handed me an essay that contained the sentence, “Their going to present there project tomorrow.”
I immediately spotted two grammar mistakes. Yet the student was surprised because the words sounded exactly the same when spoken aloud.
That is why their and they’re confuse so many people. Even native English speakers mix them up. The problem is simple: these words sound alike but have different meanings and uses.
You may have seen corrections on social media, in school assignments, business emails, or online comments. A small mistake can make otherwise excellent writing look careless.
The good news is that learning the difference is much easier than most people think.
Once you understand a simple rule, you will rarely confuse these words again. This guide explains the meaning of each word, where they come from, how to use them correctly, common mistakes to avoid, and plenty of real-world examples.
Let’s clear up the confusion once and for all.

📚The Origin: Background of Their or They’re
Understanding where these words came from can make them easier to remember.
The Origin of Their
Their comes from Old Norse, a language spoken by Vikings many centuries ago.
It developed into a possessive word that shows ownership.
Examples:
- Their books
- Their home
- Their ideas
The Origin of They’re
They’re is a contraction.
A contraction combines two words into one shorter form.
They are → They’re
English uses contractions frequently because they make speech and informal writing smoother.
Examples:
- We are → We’re
- You are → You’re
- They are → They’re
The confusion exists because both words sound exactly the same when spoken.
