Their vs There: Master the Difference Once and for All
Their is a possessive pronoun showing ownership—”their phone,” “their idea.” There points to a place or introduces a sentence—”over there,” “there is a café.”
People swap them because they sound alike when spoken quickly. In text or email, the brain hears the same sound and guesses the spelling, making the mistake feel invisible until it’s read back.
Key Differences
Their = belonging to them. There = location or sentence starter. A quick trick: if you can replace the word with “our” and it still makes sense, use their. If not, go with there.
Examples and Daily Life
Their car is parked over there. There is a line outside their favorite shop. Seeing both in one sentence helps lock the roles in memory.
Can I start a sentence with “their”?
Yes, when you’re talking about what belongs to them: “Their dog barks every morning.”
Is it ever correct to write “there” before a noun?
Yes, as an introduction: “There is a problem with the Wi-Fi.”
What if I’m still unsure?
Swap the word with “our.” If the sentence holds, use their; if it breaks, use there.
