There vs Their: The Mix Up That Trips Up Even Great Writers

There points to a place or introduces a fact, while their shows possession, meaning something belongs to a group of people. They sound the same but serve completely different jobs in a sentence.

---

I once sent a work email that read, “Please leave the files over their.” My manager replied with a single word: “there?” I felt my face go red. I knew the rule. I just typed on autopilot and missed it.

That tiny slip happens to almost everyone. These words sound identical, so our brains sometimes grab the wrong one without warning.

Texts, emails, and even published articles show this mistake constantly. Spellcheck often won’t catch it, since both words are spelled correctly, just used incorrectly.

This guide breaks the confusion apart for good, with a simple trick you’ll actually remember.

There vs Their: Quick Answer

There refers to a location, or it introduces a fact or idea. Their, on the other hand, shows ownership, meaning something belongs to more than one person.

For example, “The keys are over there” points to a location. “That is their house” shows the house belongs to them.

The Origin and Background of There and Their

There comes from Old English þǣr, meaning “in that place.” It has always pointed toward location or existence, as in “there is” or “there are.”

Their, meanwhile, traces back to Old Norse þeirra, meaning “of them.” Vikings brought this possessive form into English during centuries of contact and settlement in Britain.

So the confusion isn’t really about meaning. It’s about sound. Both words evolved along separate paths, yet English pronunciation eventually made them nearly identical.

There and Their Explained: Key Differences

Term	Meaning	When to Use	Region/Context
There	A place, or an introductory word	Pointing to location or stating a fact	Universal, all English writing
Their	Possessive form showing ownership by a group	Showing something belongs to multiple people	Universal, all English writing

Here’s a simple trick. If you can replace the word with “here,” you need there. If you can replace it with “our” or “his and hers,” you need their.

Which Word Should You Use?

• When pointing to a location → use there, as in “put it over there.”
• When showing ownership → use their, as in “their car is parked outside.”
• When starting a sentence about existence → use there, as in “there are three options.”

If you’re ever unsure mid sentence, try the substitution trick above. It works nearly every time.

Common Mistakes with There and Their

Mistake 1: Using “there” instead of “their” for possession.

• Wrong: “The students left there books on the desk.”
• Correct: “The students left their books on the desk.”
• Why it happens: The words sound identical, so the brain autopilots to the more common spelling.

Mistake 2: Using “their” when pointing to a location.

• Wrong: “The car is parked over their.”
• Correct: “The car is parked over there.”
• Why it happens: Fast typing often swaps similar sounding words without a second glance.

Mistake 3: Confusing both with “they’re,” the contraction.

• Wrong: “Their going to the store later.”
• Correct: “They’re going to the store later.”
• Why it happens: All three words sound exactly alike, creating a classic triple mix up.

Mistake 4: Relying entirely on spellcheck to catch the error.

• Wrong: Publishing a document with the wrong word, since spellcheck sees no misspelling.
• Correct: Proofread manually, or read the sentence aloud to check the meaning fits.
• Why it happens: Spellcheck flags misspelled words, not correctly spelled words used incorrectly.
