Errors in using the apostrophe abound in written English. Some writers use an apostrophe where none is warranted, while others omit an apostrophe where one is required.
its, it's, OR its'
By far the most common errors in the use of the apostrophe involve the letters i-t-s. Some writers believe, wrongly, that the apostrophe always implies possession; it does not. Therefore, we have constructions like the one below.
- The cat lost it's collar.
- The cat lost its' collar.
In the first sentence, the writer uses an apostrophe incorrectly to denote possession. The correct form to indicate possession using i-t-s is its, always.
Correct: The cat lost its collar.
The form it's means "it is" or "it has," as in "It's a great day for roller skating" or "It's been a long time since Karen came to class." This is called a contraction and should be used sparingly, if at all, in formal writing.
In the second sentence, the writer uses a form that does not exist. The form its' does not exist in standard English; it is wrong, always. To summarize,
- its = possession
- it's = "it is" OR "it has"
- its' = does not exist
who's OR whose
Another common error is confusing whose with who's.
Error: The post office manager, who's mother is in the hospital, retired.
Again, these are two words that sound the same but are spelled differently and mean different things, homophones (or homonyms). The word whose indicates possession; who's is a contraction for who is.
Correct Form: The post office manager, whose mother is in the hospital, retired.
you're OR your
Some students confuse your with you're.
Use the word your to indicate that something belongs to the person you're speaking to (hmmm).
Use you're when you are saying something about the person you are speaking to.
Error: The brown dog ran away with you're raincoat.
Think about this. Would you rewrite the sentence "The brown dog ran away with you are raincoat"? So the correct form is
Correct Form: The brown dog ran away with your raincoat.
The word your shows possession. You're means "you are."
they're, their, OR there
Here we have another error that confounds some student writers.
Error: Their not going to the movies until tonight.
Correct: They're not going to the movies until tonight.
The intended meaning is "Those people" (they) are not going to the movies until tonight.
The word their shows possession (their parking lot); they're means "they are"; there indicates location or a state of being, as in "There are three letters in the word cat."
