I grew up in a house where the dinner table doubled as a comedy club. Not the glamorous kind. The kind where someone says, “Pass the peas,” and Dad replies, “I can’t. I’m trying to ketchup.”

So when people ask why I care so much about their, there, and they’re, my answer is simple: because one tiny apostrophe can turn a perfectly innocent sentence into a public spelling bee you did not sign up for.

The 10-second cheat sheet

  • their = belongs to them (possession)
  • there = over here/there (location) or there is/are (introduces something that exists)
  • they’re = they are (a contraction)

If you remember nothing else, remember this: one of them owns something, one of them points somewhere, and one of them is two words wearing a trench coat.

Their: owns stuff

Their is a possessive word. If them owns it, it’s their.

Try the “our” test

Swap their for our (or his/her). If the sentence still works, you want their.

  • Correct: “The dogs wagged their tails.” (The dogs wagged our tails. The grammar holds, even if the image raises questions.)
  • Correct: “I borrowed their board game and returned it missing exactly one piece.”

Funny examples

  • “The squirrels held a meeting about their nut budget.”
  • “My neighbors love their new trampoline. I love it more at 6 a.m., apparently.”
  • “The pirates polished their hooks and practiced saying ‘Arrr’ in customer-service voices.”

Memory trick: their has heir inside it. Heirs inherit stuff. Therefore, their is about stuff people own.

There: points

There is used for location or to begin sentences like there is and there are.

Use “here” as a clue

If you could replace it with here (or something location-ish), it’s there.

  • Correct: “Put the snacks over there.” (You could also say “over here.”)
  • Correct: “We went there once and immediately got lost in the parking lot.”

Also: “There is” and “There are”

This is sometimes called the “existential there,” which sounds like a philosophy class, but it just means you are introducing that something exists or is present.

English also loves easing into a sentence like it is testing the water temperature.

  • “There is a spider in the bathtub that pays rent now.”
  • “There are two kinds of people: those who proofread and those who send ‘kinda’ texts to their boss.”

Memory trick: there has here in it. Location. Pointing. Gesturing dramatically for effect.

They’re: has the apostrophe

They’re is short for they are. If you can expand it to “they are,” congratulations, you have found the apostrophe’s natural habitat.

The “expand it” test

  • Correct: “They’re bringing dessert.” = “They are bringing dessert.”
  • Correct: “They’re convinced the cat understands sarcasm.” = “They are convinced…”

Funny examples

  • “They’re baking cookies, but emotionally they are baking chaos.”
  • “They’re starting a band called ‘The Silent Letters.’”
  • “They’re on a diet, which means I am also on a diet in their presence.”

Memory trick: the apostrophe in they’re is doing a job. It is replacing the missing a in are.

Common mix-ups

These words sound the same, and your brain is a speed-walking toddler dragging a backpack. It wants to get the message out. Spelling is a secondary concern.

Mistake 1: “Their” for a place

  • Incorrect: “Put it over their.”
  • Correct: “Put it over there.”

Mistake 2: “There” for ownership

  • Incorrect: “I like there shoes.”
  • Correct: “I like their shoes.”

Mistake 3: “Their” when you mean “they are”

  • Incorrect: “Their going to win.”
  • Correct: “They’re going to win.”

Memory tricks

1) The quick substitution trio

  • If you can replace it with they are, use they’re.
  • If you can replace it with here, use there.
  • If you can replace it with our (ownership), use their.

2) Picture cues

  • their: imagine a group holding a big box labeled “OURS.”
  • there: imagine pointing across the room like you are directing traffic.
  • they’re: imagine two words, “they” and “are,” squished into one seat.

3) Slow down at the danger zones

If the word appears right before a noun (shoes, dog, idea, plan), it is often their. If it appears near “is/are,” it is often there. If it appears before a verb ending in -ing (going, coming, leaving), it is often they’re.

Last-resort trick

If I catch myself hesitating, I rewrite the sentence to dodge the homophone entirely. It is not cheating. It is strategy.

  • Instead of “There is a problem,” try “A problem exists.”
  • Instead of “I like their style,” try “I like that group’s style.”
  • Instead of “They’re late,” try “They arrived late.”

Will this make you sound like a Victorian butler occasionally? Yes. Will it prevent you from texting “I love you and I’m proud of you” with a surprise spelling error? Also yes.

FAQ

Is “their” ever used for one person?

Yes. Their is often used as a singular, gender-neutral possessive: “Someone left their umbrella.” It is standard in everyday English and is increasingly accepted in formal writing too, though some more conservative style preferences still favor “his or her” or a quick rewrite.

What is the fastest way to catch mistakes?

Read the sentence out loud and run the swap test:

  • Try “they are” for they’re.
  • Try “here” for there.
  • Try “our” (or “his/her”) for their.

Does autocorrect fix this?

Sometimes. Other times, autocorrect is like a confident friend who gives directions based on vibes. It will pick a word that is spelled correctly, even if it is the wrong one. The swap test is safer.
