what is the difference between its and it's

He gave its head a little pat. It's considered polite to do that.
it is = it's (contraction)
its = a possessive pronoun

Thank you

You're welcome! Let me explain the difference between "its" and "it's."

"Its" is a possessive pronoun that shows that something belongs to or is associated with an object. For example, in the sentence "He gave its head a little pat," "its" shows that the head belongs to an object or animal that is being referred to.

On the other hand, "it's" is a contraction of "it is" or "it has." In the sentence "It's considered polite to do that," "it's" is used to mean "it is." The word "it's" combines the pronoun "it" with the verb "is" in this case.

To remember the difference, it can be helpful to break down the contraction "it's" into "it is" or "it has" to check if it makes sense in the context of the sentence. If it does, then "it's" is the correct choice. Otherwise, use "its" to show possession.

I hope this clarifies the difference for you! If you have any more questions, feel free to ask.
