When is its' used in grammar?

Answer 1

There is no such word as its'.

There are only two forms: it's and its. It's is a contradiction for "it is" or "it has." Its is a possessive pronoun meaning "of it" or "belonging to it." A simple way to test when to use it's or its is this: if you can replace the word "it's" in a sentence with "it is" or "it has," then the correct word is "it's." If you cannot replace the word, then the correct word is "its." Good luck!

Answer 2

"Its" is used as a possessive pronoun to show ownership or belonging to something. It does not have an apostrophe, unlike the contraction "it's," which is a shortened form of "it is" or "it has."
