“Their” vs. “There” vs. “They’re”: Do You Know The Difference? The trio of their, there, and they’re can flummox writers of all levels.

She is there now. There is also used as a pronoun introducing the subject of a sentence or clause: There is still hope. When to use they’re They’re is a contraction of the words they and are. They’re mastering the differences between three homophones! Take a hint from the spelling! If you find yourself coming up blank when trying to determine which one to use, take a hint from the spelling of each: Their has the word heir in it, which can act as a reminder that the term indicates possession. There has the word here in it. There is the choice when talking about places, whether figurative or literal. They’re has an apostrophe, which means it’s the product of two words: they are. If you can substitute they are into your sentence and retain the meaning, then they’re is the correct homophone to use.
