“They’re,” “their,” and “there” are homophones with different grammatical jobs. They’re means “they are,” their expresses ownership or association, and there identifies a place or introduces existence. The fastest reliable method is to test “they are” first, check ownership second, and use “there” for location or existence.
Key Facts at a Glance
They’re is the contraction of they are: “They’re ready” means “They are ready.”
Their is a possessive determiner placed before a noun: “Their tickets were expensive.”
There can indicate a location: “The keys are over there.”
There can introduce existence: “There are three keys on the desk.”
Theirs is different from their because theirs stands alone and is not followed directly by a noun.
Pronunciation usually cannot identify the correct spelling because all three words commonly sound alike.
What Is the Difference Between They’re, Their, and There?
The difference between they’re, their, and there is grammatical function, not pronunciation. They’re contains a verb, their marks possession before a noun, and there refers to a place or introduces a clause about something existing.
| Word | Full form or role | What it communicates | Example |
|---|---|---|---|
| they’re | they are | An action, condition, or identity | They’re waiting outside. |
| their | Possessive determiner | Belonging or association | Their bags are outside. |
| there | Adverb or introductory pronoun | Place, position, or existence | There are bags outside. |
| theirs | Independent possessive pronoun | Belonging without a following noun | The bags are theirs. |
The words belong to the same sound family but cannot substitute for one another. Replacing the blank with its grammatical meaning exposes most errors immediately.
For example, “They’re studying” expands to “They are studying.” “Their books” answers the question “whose books?” “Put the books there” answers the question “where?”
When Should You Use They’re?
Use they’re when the sentence means they are. The contraction can introduce a present action, a description, a location, or a noun phrase, as in “They’re running,” “They’re tired,” “They’re at school,” and “They’re the winners.”
The apostrophe marks omitted letters. In they’re, the apostrophe replaces the “a” in they are.
| They’re sentence | Expanded sentence | Function after “are” |
|---|---|---|
| They’re preparing dinner. | They are preparing dinner. | Present participle |
| They’re unusually quiet. | They are unusually quiet. | Adjective |
| They’re in the library. | They are in the library. | Prepositional phrase |
| They’re my neighbors. | They are my neighbors. | Noun phrase |
| They’re going to call later. | They are going to call later. | Future expression |
How does the “they are” test work?
Replace they’re with they are without changing the rest of the sentence. If the expanded sentence is grammatical and keeps the intended meaning, they’re is correct.
- “I think they’re finished.”
“I think they are finished.” Correct. - “The students brought they’re lunches.”
“The students brought they are lunches.” Incorrect. - “They’re bicycles are outside.”
“They are bicycles are outside.” Incorrect.
A common editing mistake is testing only the sound. Spoken English often reduces “they are” to something close to “they’re,” so the ear cannot reliably choose the spelling. Test the expansion instead.
When Should You Use Their?
Use their before a noun to show that something belongs to, relates to, or is associated with people, animals, organizations, or a singular person. Their functions as a possessive determiner, traditionally also called a possessive adjective.
| Possessor | Their + noun | Meaning |
|---|---|---|
| Two athletes | their uniforms | The uniforms of the athletes |
| A family | their house | The house of the family |
| A company | their policy | The policy of the company |
| Several dogs | their bowls | The bowls used by the dogs |
| One applicant | their résumé | The résumé belonging to the applicant |
Ownership is broader than legal possession. “The team changed their strategy” describes association, while “The child held their parent’s hand” describes a relationship.
Can their refer to one person?
Yes. Their can refer to one person when the person’s gender is unknown, irrelevant, or when the person uses they/them pronouns. Major English style guides and dictionaries recognize singular they as an established modern usage.
- “Every student must submit their assignment by Friday.”
- “Alex left their phone in the classroom.”
- “Someone forgot their umbrella.”
The singular verb still agrees with the singular subject when appropriate: “Every student has their own account,” not “Every student have their own account.” The possessive form remains their, even though the possessor is singular.
Does their always show ownership?
No. Their can indicate connection, responsibility, origin, or characteristic rather than ownership.
- “The birds returned to their nest.”
- “The engineers tested their design.”
- “The museum updated their opening hours.”
- “The patient described their symptoms.”
In each example, their appears before a noun or noun phrase. That position is a stronger diagnostic than the ownership mnemonic.
When Should You Use There?
Use there for a location, direction, position, or statement of existence. In “The coat is there,” there points to a place. In “There is a coat on the chair,” there introduces the existence of a coat.
| Use of there | Question answered | Example |
|---|---|---|
| Physical location | Where? | Leave the parcel there. |
| Abstract location | Where in an idea or process? | The difficulty lies there. |
| Direction | Toward which place? | Look there for the missing file. |
| Existence | What exists? | There is one solution. |
| Attention-getter | What should I notice? | There, the problem is fixed. |
How does existential there work?
Existential there introduces a noun that exists, appears, remains, or occurs. The verb agrees with the noun that follows, not with the word there.
- “There is one problem.”
- “There are two problems.”
- “There was a delay.”
- “There were several delays.”
- “Is there a printer nearby?”
- “Are there enough seats?”
In formal edited writing, plural nouns normally take are: “There are several reasons.” Informal speech sometimes uses “there’s” before plural nouns, but that pattern is less suitable for school assignments, reports, and careful professional prose.
Is there always a physical place?
No. There can refer to an abstract point or introduce existence without pointing to a visible location.
- “There is no reason to panic.”
- “The answer is there in the final paragraph.”
- “There are risks in changing the schedule.”
- “We reached a point where there was no alternative.”
The location mnemonic involving here helps with “over there,” but it does not explain existential sentences such as “There are three possibilities.”
How Do the Three Words Compare in Real Sentences?
The following pairs show how changing one spelling changes the sentence’s grammatical meaning.
| Incorrect or contrasting form | Correct form | Reason |
|---|---|---|
| Their leaving at noon. | They’re leaving at noon. | “They are leaving” is required. |
| They’re jackets are wet. | Their jackets are wet. | The word precedes the noun “jackets.” |
| Put the boxes in their. | Put the boxes in there. | The sentence names a location. |
| There planning a new route. | They’re planning a new route. | “They are planning” fits. |
| The files are they’re. | The files are there. | The sentence points to a place. |
| The files are their. | The files are theirs. | A standalone possessive is required. |
What is the difference between their and theirs?
Their comes before a noun, while theirs replaces a noun phrase and stands independently. The two forms are possessive, but their syntactic positions differ.
| Possessive form | Required position | Correct example |
|---|---|---|
| their | Before a noun | Their decision surprised us. |
| theirs | After a linking verb | The decision was theirs. |
| their | Before an adjective plus noun | Their new decision surprised us. |
| theirs | As a subject complement | The blue folder is theirs. |
Do not write “theirs decision” or “the decision is their.” Use their decision and the decision is theirs.
What Is the Fastest Way to Choose the Correct Word?
Choose the correct spelling with a three-question decision process: test they are, test for a following noun and possession, then test for place or existence. The order matters because they’re contains a complete subject-and-verb meaning, while their and there do not.
- Can the blank expand to “they are”?
Use they’re.
“___ ready” becomes “They are ready.” - Does the blank come before a noun associated with people or a group?
Use their.
“___ final report” answers “whose final report?” - Does the blank identify a place, direction, or existence?
Use there.
“Put it ___” means “at that place.” - Does a possessive word need to stand alone?
Consider theirs, not their.
“The blue seats are theirs.”
Which memory tricks help?
The most useful memory devices are they’re = they are, their contains “heir,” and there contains “here.” These clues support recall, but grammatical substitution remains more reliable because “their” does not always describe literal property and “there” does not always describe a physical place.
- They’re: apostrophe means letters are missing.
- Their: an heir receives possessions.
- There: “here” is embedded in the spelling.
- Theirs: the possessive form that stands alone.
Expert proofreading rule: use the mnemonic to generate a candidate, then verify the sentence structure. Memory clues identify patterns; syntax confirms them.
Why Do These Words Cause So Many Errors?
These words cause errors because they are homophones, meaning they share pronunciation while retaining different spellings and meanings. Speech gives listeners sound, but writing must encode grammatical function, so fast drafting often produces the wrong form.
| Error pattern | Why it happens | Reliable correction |
|---|---|---|
| “Their going home” | The writer follows pronunciation | Expand to “They are going home” |
| “Put it over they’re” | The writer hears a location phrase | Replace with “at that place” |
| “They’re car is red” | The apostrophe looks familiar | Check whether a noun follows |
| “There results were mixed” | Location and possession are confused | Ask “whose results?” |
| “The results are their” | The independent form is missing | Use “The results are theirs” |
The error is not a sign that the writer misunderstands the underlying idea. It often appears during revision because a spellchecker may recognize all three words as correctly spelled individual tokens.
How Should You Correct a Sentence With a Homophone Error?
Correct a homophone error by identifying the blank’s grammatical role before checking spelling. Read the complete sentence, isolate the phrase around the word, apply the expansion or replacement test, and then reread for meaning.
Use this four-step editing routine:
- Circle the word and read the whole sentence.
- Expand “they’re” to “they are.”
- Ask “whose?” if a noun follows.
- Ask “where?” or “does something exist?” for there.
Example:
The volunteers said their going to place there supplies over they’re.
- “Their going” becomes “They are going,” so use they’re.
- “there supplies” answers “whose supplies?” so use their.
- “over they’re” identifies a place, so use there.
Corrected sentence:
The volunteers said they’re going to place their supplies over there.
The sentence contains all three forms correctly when each word performs its own grammatical job.
What Are Important Edge Cases?
Several constructions require more than a simple location or ownership mnemonic. There can begin a clause, their can refer to one person, and they’re can occur before a noun phrase that describes identity.
Their being late
In “I disliked their being late,” their is a possessive form before a gerund phrase. The sentence means “I disliked the fact that they were late.” This formal construction differs from “They’re being late,” which means “They are currently being late” and is usually less natural.
They’re there
A sentence can correctly contain both words:
They’re there near the entrance.
Here, they’re means “they are,” while there identifies the location. The words may sound similar, but their functions remain separate.
There, their, and they’re together
All three forms can appear in one sentence:
They’re taking their coats over there.
The sentence expands to “They are taking the coats associated with them at that place.”
Fixed compounds
Words such as therefore, thereafter, therein, and thereof contain there, but they are not interchangeable with the standalone word. “Therefore” means “for that reason,” while “thereafter” means “after that event.”
Formal editing limitation
The substitution test is excellent for ordinary sentences, but it does not replace a full grammar check. Questions involving ellipsis, quotations, legal phrasing, or dialect may require examining the entire clause rather than the neighboring two words.

Answer key with explanations
| Number | Answer | Completed sentence | Test |
|---|---|---|---|
| 1 | there | Place the forms over there. | Location |
| 2 | their | The researchers presented their findings. | Possession before a noun |
| 3 | They’re | They’re planning to revise the schedule. | They are planning |
| 4 | There | There are several reasons. | Existence |
| 5 | their | Their dog had escaped. | The dog belongs to the neighbors |
| 6 | they’re | They’re already inside. | They are inside |
| 7 | theirs | The red bicycles are theirs. | Standalone possessive |
| 8 | there | Put the batteries in there. | Location |
| 9 | their | Every applicant should check their email. | Singular they possessive |
| 10 | they’re | They’re reviewing the proposal. | They are reviewing |
| 11 | There | There was a loud noise. | Existence |
| 12 | their | We admired their ability. | Possession or association |
| 13 | their | The students left their notebooks. | Possession before a noun |
| 14 | theirs | The final decision was theirs. | Independent possessive |
| 15 | they’re | If they’re late, we will begin. | If they are late |
A score of 13-15 indicates reliable control in ordinary sentences. A score of 10-12 suggests that the basic distinction is established but existential there and theirs need more practice. A score below 10 calls for repeating the substitution tests with shorter sentences.
Practice Examples by Sentence Pattern
Pattern-based practice is more effective than memorizing isolated examples because each pattern connects a spelling to a repeatable grammatical structure.
| Sentence pattern | Example | Correct form |
|---|---|---|
| ___ + adjective | They’re prepared. | they’re |
| ___ + noun | Their equipment arrived. | their |
| Verb + ___ | Leave it there. | there |
| ___ + be + noun | There is a solution. | there |
| Noun + be + ___ | The equipment is theirs. | theirs |
| If ___ + adjective | If they’re available, call them. | they’re |
| Every person + ___ + noun | Every guest brought their ticket. | their |
| Look or point + ___ | Look there. | there |
Expert rule of thumb: the word immediately after the blank often reveals the answer, but not always. Their normally precedes a noun, while they’re normally precedes an adjective, verb phrase, location phrase, or noun phrase that completes “they are.”
FAQ
Are they’re, their, and there pronounced the same?
In most varieties of contemporary English, they’re, their, and there are homophones. Some speakers preserve slight vowel differences, but pronunciation is not a dependable spelling test. Writers should use sentence meaning and grammatical structure instead of relying on how the word sounds.
Is “their” a pronoun or an adjective?
Traditional grammar often calls their a possessive adjective, while many modern grammars call it a possessive determiner. The label differs, but the practical rule is stable: their appears before a noun phrase, as in “their plan” or “their three bicycles.”
Can I use their with a singular noun?
Yes. Their can modify a singular noun when the possessor is a singular person using they/them pronouns or when the person’s identity is unknown or irrelevant. Examples include “Alex updated their profile” and “Each guest received their badge.”
Should I write “there is” or “there are”?
Use there is with a singular noun or an uncountable noun, and use there are with a plural noun in formal standard English. Write “There is one mistake,” “There is useful information,” and “There are four mistakes.”
What is the difference between “they’re going” and “their going”?
“They’re going” means “they are going.” “Their going” is a possessive construction that treats the act of going as a noun-like phrase, as in “I objected to their going alone.” Ordinary statements about an action generally require they’re.
Is there a worksheet for younger students?
Yes. Younger students can begin with three substitutions: they’re equals “they are,” their answers “whose,” and there answers “where.” Start with one-word blanks in short sentences, then introduce theirs, existential there is, and singular their after the basic distinction is secure.
The Bottom Line
The difference between theyre their there the difference examples worksheet answers a spelling problem through grammar: they’re means “they are,” their comes before a related noun, and there identifies a place or introduces existence. Use theirs when the possessive must stand alone. Expand the contraction, ask “whose,” and ask “where” before submitting or publishing your writing.
