Have you ever written “there” when you meant “their”? Don’t worry. Almost everyone does this at some point. Understanding their meaning is one of the trickiest parts of learning English, but it’s also one of the easiest things to fix once you know the trick.
This guide is for anyone who gets mixed up between their, there, and they’re. It’s for students working on homework. It’s for adults writing emails. It’s for anyone who wants to sound smart and clear when they write.
By the end of this guide, you will know exactly what “their” means. You will know how to use it in a sentence. And you will never feel confused about it again.
Quick Answer
Their meaning, in short: “their” is a word that shows something belongs to more than one person. It means “belonging to them.” For example, “The kids lost their meaning toys” means the toys belong to the kids. It is different from “there” (a place) and “they’re” (short for “they are”).

What Does “Their” Mean?
“Their” is a small word with a big job. It is called a possessive pronoun. That’s a fancy way of saying it shows who owns something.
When you say “their,” you are talking about something that belongs to two or more people. Or it can belong to one person whose gender you don’t know.
Here’s an easy way to picture it. Imagine three friends: Sam, Alex, and Jo. They all own one red bike together. You would say, “That is their meaning bike.” One word tells you the bike belongs to all three of them.
That is the true their meaning. It points to ownership. It always points to more than one owner, or to a person you don’t want to label as “he” or “she.”
Their vs. There vs. They’re
This is the part that trips up almost everyone. These three words sound exactly the same when you say them out loud. But they mean completely different things.
| Word | What It Means | Example |
| Their | Shows ownership | “Their dog is friendly.” |
| There | Shows a place | “The dog is over there.” |
| They’re | Short for “they are” | “They’re walking the dog.” |
Here is a simple trick to keep them straight:
- their meaning has the word “heir” hiding inside it. An heir is someone who inherits or owns something. So “their” is about owning things.
- There has the word “here” hiding inside it. Both are about places.
- They’re has an apostrophe. An apostrophe often means two words got squeezed into one. “They’re” is just “they are” squeezed together.
Once you spot these hidden clues, you will almost never mix them up again.
How to Use “Their” in a Sentence
Using “their” is simple once you know the pattern. You use it right before a noun (a person, place, or thing) to show that the noun belongs to a group.
Here is the basic pattern:
Their + [noun]
- Their house
- Their homework
- Their idea
- Their favorite song
Let’s put that into full sentences:
- The students finished their meaning homework early.
- My neighbors painted their meaning fence blue.
- Everyone should bring their own lunch.
- The team celebrated their big win.
Notice how “their” always comes before a thing that belongs to someone. That is the whole secret to using it correctly.
When to Use “Their” for One Person
Sometimes people use “their” even when they are talking about just one person. This happens when we don’t know if that person is a boy or a girl, or when we simply don’t want to guess.
For example: “Someone left their jacket on the chair.”
We don’t know if that someone is male or female. So “their” works perfectly here. This has been a normal part of English for hundreds of years, and most style guides now accept it.
Where Does the Word “Their” Come From?
Words have histories, just like people do. “Their” is a very old word. It came from an Old Norse word, “þeirra,” used by Viking settlers in England a long time ago.
Old English speakers already had words like “hira” for “their,” but over time, the Norse version won out and became the “their” we use today. Language often changes this way. New words move in, old words fade out, and eventually, the new word becomes completely normal.
Knowing this history won’t change how you use the word today. But it’s a fun fact that shows how English has borrowed from many different languages over the centuries.
Common Mistakes People Make
Even smart, careful writers slip up with “their.” Here are the mistakes that happen most often.
Mistake 1: Swapping “their” for “there.” Wrong: “Put the box over their.” Right: “Put the box over there.”
Mistake 2: Swapping “their” for “they’re.” Wrong: “Their going to the park.” Right: “They’re going to the park.”
Mistake 3: Using “their” with one clear owner. Wrong: “Give the book to their,” when you already know it’s Maria’s book. Right: “Give the book to her.”
Mistake 4: Forgetting the noun after “their.” Wrong: “That is their,” with nothing after it. Right: “That is their book.”
Spotting these patterns in your own writing is the fastest way to stop making them.
Expert Tips to Remember Their Meaning
Teachers and writing coaches use a few simple tricks to help students lock in their meaning for good.
- Say the sentence out loud, but swap in “our.” If “our” makes sense, “their” is probably correct too. “That is (our/their) house” both work, so “their” is right.
- Look for the hidden “heir.” If the sentence is about who owns something, think “heir” and reach for “their.”
- Read your writing backward. Reading sentences in reverse order forces your brain to look at each word on its own, which makes mix-ups easier to spot.
- Use a find-and-replace check. Before turning in important writing, search for “their,” “there,” and “they’re” and double-check each one by hand.
These habits take only a few seconds but save you from small errors that can make good writing look sloppy.
Examples of Their in Real Sentences
Seeing “their” used in different situations helps the meaning stick. Here are examples from everyday life.
- At school: “The class shared their art projects with the principal.”
- At home: “My parents renovated their kitchen last summer.”
- At work: “The company updated their website this week.”
- In sports: “The players signed autographs after their victory.”
- In nature: “Birds build their nests high in the trees.”
- In stories: “The heroes returned to their village as legends.”
Each sentence follows the same rule. Something belongs to more than one person (or a person whose gender isn’t stated), and “their” shows that ownership.
Myths About “Their”
A few myths float around about this little word. Let’s clear them up.
Myth: “Their” can only refer to groups of people. Not true. “Their” can also describe one person when the gender is unknown or unimportant, as we saw in the “someone left their jacket” example.
Myth: Using “their” for one person is a new, incorrect trend. Not true. Writers have used “their” this way for centuries, long before it became a hot topic online.
Myth: “Their” and “there” are interchangeable if the sentence still makes sense. Not true. They have completely different jobs. Mixing them up is always considered an error in formal writing, even if a reader can guess what you meant.
Their in Formal vs. Casual Writing
Not every kind of writing treats their meaning the same way. Knowing the difference helps you pick the right style for the right moment.
In casual writing, like texts, chats, or social media, “their” is used freely for both groups and single people. Nobody blinks if you write, “Ask the driver for their name.”
In formal writing, like school essays, business reports, or legal papers, some older style guides still prefer “his or her” instead of “their” for one unknown person. But this is changing fast. Many major style guides, dictionaries, and universities now fully accept singular “their” in formal writing too.
Here is a simple table to help you choose:
| Setting | Common Choice | Example |
| Texting a friend | “their” | “Tell them to bring their charger.” |
| School essay (older style) | “his or her” | “Every student must bring his or her ID.” |
| Modern formal writing | “their” | “Every student must bring their ID.” |
| Business email | “their” | “The client updated their order.” |
When in doubt, “their” is almost always a safe, modern, and widely accepted choice.
Pros and Cons of Using “Their” for One Person
Using “their” to talk about a single person, instead of “he” or “she,” has real benefits and a few small drawbacks worth knowing.
Pros:
- It works when you don’t know someone’s gender.
- It respects people who don’t identify as strictly male or female.
- It keeps sentences short. You avoid clunky phrases like “he or she.”
- It has been part of English for a very long time, so it sounds natural.
Cons:
- A few very strict teachers or editors may still mark it as incorrect.
- Some readers might briefly pause if they aren’t used to seeing it.
- In very formal legal writing, some documents still spell out “he or she” to avoid any confusion.
Overall, the pros outweigh the cons for almost every situation you’ll run into.
A Quick Checklist Before You Hit Publish
Before you send an email, turn in homework, or post online, run through this short checklist. It only takes a few seconds.
- Did I use “their” to show something belongs to someone?
- Did I use “there” only when talking about a place?
- Did I use “they’re” only as a short form of “they are”?
- Did I read the sentence out loud to see if it sounds right?
- Did I check any sentence that felt tricky one more time?
If you can answer “yes” to all five, your writing is in great shape.
Safety and Trust: Why Small Word Mix-Ups Matter
You might wonder why a tiny word like “their” is worth so much attention. Here’s the honest answer: word mix-ups can quietly hurt how people see your writing.
A mixed-up “their” won’t confuse most readers about the meaning of your sentence. But it can make a resume, a work email, or a school paper look rushed or careless. Getting their meaning right builds trust with your reader. It shows that you care about the details, which matters in school, at work, and online.
The good news is that this is one of the easiest writing habits to fix. A little practice goes a long way.
