Their, There and They’re A lot of native speakers make this mistake, too but learning the difference is surprisingly simple. ✅Their is a possessive pronoun which denotes belonging to something. “Their house is so pretty!” ✅There denotes a place. “There’s the mall.” ✅They’re is short for ‘they are’. “They’re so silly for two grown-up men.” “They’re (the two boys) are going there (to school) to finish their (belonging to the two boys) education.”
