Their or They’re : The Quick Fix You Need to Know✍️(2026)

I remember typing a quick message: “Their going to be late.” I paused. Something felt wrong. I had seen they’re used in the same kind of sentence. So which one was right?

If you’ve had this confusion, you’re not alone. Many people search for “their or they’re” because the words sound the same but have different meanings. These are called homophones, and they often cause mistakes in writing.

The problem is simple: one word shows ownership, and the other is a short form of two words. If you mix them up, your sentence can look unprofessional or confusing.

In this guide, I’ll explain the difference in a very simple way. You’ll learn when to use their and when to use they’re, with clear examples. By the end, you’ll never mix them up again.

✅ Their or They’re – Quick Answer

Their → ✅ Shows possession (something belongs to them)
They’re → ✅ Short form of they are

👉 Examples:

That is their car. ✅
They’re going to the park. ✅

❌ Their going to the park. (Wrong)
❌ They’re car is new. (Wrong)

✔️ Simple rule:
Their = ownership | They’re = they are

📜 The Origin of Their or They’re

Both words come from Old English and Norse roots:

Their comes from Old Norse þeira, meaning “of them”
They’re is a contraction of they are

Over time:

“Their” stayed a possessive word
“They’re” was created by combining two words

👉 So:

Their → shows belonging
They’re → shows action/state (they are)
