Does it matter what spelling you use, There, Their or They’re?
Yes it does matter. Why you ask. Because they all have totally different meanings.
If the meanings were the same, then I would have no issue with the spelling, but because since all three mean totally different things.
There – Indicates location.
Example: She is over there.
Their – Indicates ownership.
Example: That is their cat.
They’re – Indicates Activity.
Example: They’re riding the bus.
