Origin of its

1590–1600; earlier it's, equivalent to it1 + 's2

words often confused with its

A very common mistake is to write its (the possessive form of it ) when it's (the short form of it is or it has ) is required: It's [it is] unclear what he meant. It's [it has] been wonderful seeing you again. But do not use it's for it has when has is the main verb: It has a strong flavor; use it sparingly cannot be written as It's a strong flavor… An equally common mistake is to use it's for the possessive, probably because ordinary possessives of nouns are formed with an apostrophe: the dog's coat; Mary's cell phone. But the possessive its is a pronoun, not a noun, and, like other possessive pronouns ( his, hers, yours, and theirs ), is written without that particular bit of punctuation: I have to fix my bike. Its front wheel came off.

usage note for its

While it is possible to use its as a predicate adjective ( The cat is angry because the bowl you're eating out of is its! ) or as a pronoun meaning “that or those belonging to it” ( Your notebook pages are torn. Borrow my notebook—its aren't ), such use is rare and in most circumstances strained. See also me.

ITS VS. IT'S

What’s the difference between its and it's?

Its is the possessive form of the pronoun it—it means belonging to it. It’s is a contraction of it is or it has—meaning that it’s a combination of the two words, making it shorter to say.

The confusing part is that possession is often indicated by an apostrophe and the letter s (’s), as in That is Mike’s car or Is this anyone’s jacket? But some possessive pronouns—including hers, theirs, and its—just add s on the end, without an apostrophe. Its is the most potentially confusing because it is very commonly used with the verb is (unlike her and their, which are never used with is because they are never used as subjects).

As a possessive, its is typically applied to animals or objects in discussion of their parts or qualities, as in This container is missing its lid or Look at that bird—its beak is so long!  

If you can substitute it is for the word you’re using, then you want it’s. Remember, the apostrophe part of the contraction is really standing in for the letter i in the word is.

Here’s an example of its and it’s used correctly in the same sentence.

Example: Have you seen my suitcase? It’s¹ black and its² zipper is red and it’s³ got a ton of stuff in it.

1 = It is
2 = possessive
3 = it has
