They’re over there on their chair

Bing’s at it again, the ol’ grammar freak.

I know what he means, because there are some very strange things in the English language. One of them is the difference between they’re, there and their. It’s not hard in conversation, but boy can it get confusing when you have to write it down.

They’re is a contraction of “they are”. It means “they are” and nothing else, as in “They’re a bunch of crazy people”.

There is the opposite of here, as in “The book is over there“; or refers to a place, point or stage, as in “He went there after work” or “There is where I disagree with your statement”; or is used to express satisfaction, approval or sympathy, as in “There, I’m finished” or “There, there. Don’t cry”. 

Their refers to possession, as in “They took their work home with them”, or “Is that their new office?”. 

Consequently, the following must be correct:
There, there, fair bear. Their rare pears are over there on their chair. They’re fair, those pears; but they’re not meant for fare. They’re meant to stay there, on their chair, those rare pears. There, there, fair bear.”
