Is It's a singular possessive

Answer 1

No, it's is a contraction of it is or it has. The possessive form of it is "its."

Possessive pronouns don't use an apostrophe to indicate possession, the pronoun itself is the possessive form.

If you're not sure which form to use, try the sentence with "it is" instead. If it makes sense, use "it's"; otherwise use "its". For example, which is correct? "The wind changed it's direction." or "... its direction."? If you change to "it is", the sentence becomes "The wind changed it is direction." which is nonsense grammatically. That means the correct wording is "The wind changed its direction."

Answer 2

Yes, "its" is a singular possessive pronoun used to show that something belongs to "it."
