They're They're is a shortened version of they are. (The apostrophe replaces the letter a.) Only use they're if you can substitute it with they are. Their Their is used to show possession. It is just like my, your, his, her, its, and our. (These are called possessive adjectives.) Here is a little trick: use the word our instead of their. If the sentence still makes sense, then their is almost certainly correct. This trick works because our and their are both possessive adjectives used for plurals. There The word there is similar to the word here in that it represents a place. It has two main uses: (1) it is a specified place (like in the first example below), and (2) it is an unspecified place (like in the second example). Also, like in the second and third examples, the word there can be used to show that something exists. Their you go! I hope this helps y'all. (Especially @Madii )
It's irritating when people use the wrong 'there'. But I don't think a single thread will suddenly make these people understand. Nice thread btw.
And unfortunately, when you grow up and have adult friends on Facebook, people still massacre their, there, and they're. All.The.Time.
I wish that people could tell the difference, but sadly I don't think that there ever going to get it.
