- I spent the night in there kitchen, dancing!
- They’re is a huge spider next to the toilet.

When it isn’t used to indicate a place (“over there”), at the beginning of a sentence, there is called an existential pronoun. They tend to weaken a sentence (“There is rain”), and they’re best omitted. The apostrophe in they’re indicates a contraction: they are. Their derives from Old Norse, “of them,” which makes sense, since it’s the possessive form of they. “Their parents are so glad they finally married.” Even though they sound alike, separate them in your mind when you write them out.

Their and there, in particular, sound identical in much of the English-speaking world; they’re is sometimes closer to “they-r” in pronunciation. Because of the fact that we speak them much more often than we write them, making them distinct in writing is usually the least of our worries.
