According to the readers of my blog, the distinction between “it’s” and “its” is the top pet peeve and common error out in the writing world. This article attempts to explain the distinction between the two words.
“It’s” is a contraction. Most of us have heard of and are familiar with contractions. Here’s how they work:
If you want to say “Here is” and be less formal about it, squash the words together and substitute an apostrophe for the last vowel (“I”) to create “Here’s.” If you want to say “Do not” less formally, squash the words together and substitute an apostrophe for the last vowel [“o”] to create “Don’t.”
This process of contraction is how we get many words such as: can’t; doesn’t; aren’t; there’s; and (drumroll please)… it’s!
How simple is that? If you want your word to mean “it is” or “it has” then just make a contraction: it’s.
Examples:
It is time for bed. = It’s time for bed.
It is a girl! = It’s a girl!
It has been raining for days. = It’s been raining for days.
These examples seem simple enough. I think where people get flummoxed is when they want a word meaning “belonging to ‘it.’”
Why is this one confusing?
When something belongs to Harry we add an apostrophe after “Harry” and say it’s “Harry’s.” When something belongs to the barber we add an apostrophe and say it’s the “barber’s.” However, when it comes to saying something belongs to “it,” the apostrophic form goes out the window, i.e. we do NOT use an apostrophe. Something belonging to “it” is “its.”
Why is there no apostrophe in “its”?
Note there are other times we do not use an apostrophe to show possession. When something belongs to “her” we say it’s “hers.” When something belongs to “him” we say it’s “his;” when something belongs to “us” we say it’s “ours” and when something belongs to “them” we say it’s “theirs.” There are many irregular constructions here. Yet somehow most people don’t make mistakes when it comes to these other possessive forms. It’s “its” that continues to baffle us.
You might notice something in common about all the examples where apostrophes are not used to show possession: they are all a part of speech we refer to as a pronoun. Pronouns are our shortcuts so that we do not have to keep referring to people and things by their name or other descriptor. They are a referential shortcut. They replace, or substitute for, nouns.
I will write more about pronouns in a future article where I will talk about the use of “I” and “me.” For now you can look at http://www.uottawa.ca/academic/arts/writcent/hypergrammar/pronouns.html for more information. Some examples of pronouns are he, she, they, you; her, him, us; our, their, and its.
Here’s your rule to remember: When forming a possessive PRONOUN, do NOT use an apostrophe. Since “it” is a pronoun, we do NOT put an apostrophe after it to make it possessive. Just as you would not write “her’s” or “our’s,” do not write “it’s” when you are intending to show possession.
It’s my fervent hope this article has cleared up some common misperceptions and that its contents will be distributed widely by its readers!
