What is the possessive noun its or it's?

Answer 1

Even though it doesn't have an apostrophe, its is the possessive form of the word it, which is a pronoun rather than a noun.

It's is the short form for it is.

The words its and it's confuse many people because most English words make their possessive form by adding " 's ", but personal pronouns are an exception to that rule. That exception is why we write hers instead of "her's" or yours instead of "your's".

If you're not sure which one to use, remember that it'sis short for it is. If the sentence makes sense with "it is" instead, use it's. Otherwise, use its. For example, which is correct?

1. The dog ate it's dinner.
2. The dog ate its dinner.

If you replace it's with it is in the first sentence, it becomes "The dog ate it is dinner." which is gibberish. That means the second sentence has the correct usage.

Answer 2

The possessive form of "it" is "its" without an apostrophe. "It's" is a contraction for "it is" or "it has."
