there/their/they're

Just as misusing "your" and "you're" makes an English teacher want to cry in his or her Cheerios, this triumvirate of words causes the same hysterical reaction.

I know you people are aware of the correct usage of each word, but, for some reason, you don't go back and make sure you've used the correct one. For the love of all that is sacred, will you do that for me? Pretty please? Let's review.

"There" is an adverb. It tells "where." Correct uses would be, "Put the box over there," or "Stand there," or "I'm not going there, or anywhere else, with you."

By itself, "their" is a possessive pronoun, but it is used as an adjective. "Their books," "their car," "their elephant," or "their whoopie cushion" all indicate which one.

"They're" is simply a contraction meaning "they are." If you don't mean to say "they are," then please don't use it. Can it be any simpler?

Just slow down and think about which form you want to use.

They're going to pick up their new car at the dealership over there.

Done.
