There vs Their vs They’re: Keeping Them Straight

Misuse of these three words is another one of those mistakes that draws a red flag. The three couldn’t be more different in their meanings and uses which makes mistakes stand out so much. And like many others we considered, it’s an error that word processors often fail to catch.

Defining the Three Amigos

  • There means in that place.
  • Their is the possessive of they.
  • They’re is a contraction that means they are

Using There

There is a jack-of-all-trades as an adverb, pronoun, noun, adjective or even interjection. Perhaps that’s part of the reason it gets misused. We’re so used to using it in so many ways that it becomes our go-to word.

As an adverb, there identifies a particular place, manner or point in time. You can also use it as a pronoun before the verb and subject. Using there can identify a condition or be used for emphasis as an interjection. Between there vs their vs they’re, you’ll likely use it the most.


  • There is the museum on the right.
  • She drove the car there.
  • There is no peanut butter left.
  • There! I told you so.

Using Their

Their is the possessive form of they which is its most common use. You’ll often see it used as an ambiguous way to refer to both her and his in a sentence. It’s a less cumbersome way than switching back and forth between the pronouns of the two genders. It is the possessive form of they. You’ll also see the word, theirs, which refers to the possessive of them.


  • Someone forgot their keys on the table.
  • They brought their lawn chairs to the park.
  • The car is theirs.

Using They’re

Unlike the others, its use is definite. There isn’t any mistaking why it is used and when. Errors often are a matter of being in the wrong place at the wrong time. Don’t fret if it’s shown up in your writing. It’s probably one mistake we’ve all made at some point.


  • They’re buying a new house next spring.
  • They’re going on vacation.

Stopping Errors Before They Occur

One of the problems with there vs their vs they’re is that they all begin with the same three letters. If you have autocomplete enable on your word processor, it’ll likely pick the one you use most often—regardless if it’s the right choice or not. And then, you’re left with that nasty problem of the misspelling breezing past the spellchecker.

If this error turns up a lot in your writing, you should disable autocomplete so that you have that extra split second to consider your word choice as you go. This easy fix will likely catch most errors.

There vs their vs they’re often crop up even in the most polished text. It’s not so much a matter of confusing the words as it is reaching for the familiar one at the time even if it’s not the right one. And it’s another example of the limitations of a spellchecker. Sometimes a thorough read is the best editor you can find.
