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.”
