Is it's a possesive pronoun

Answer 1

"It's" is a contraction for "it is'. The possessive pronoun is written "its" (no apostrophe).

The best way to decide which word to use is to try using "it is" instead. If the sentence still reads correctly then use "it's" (with the apostrophe. If it doesn't make sense with "it is" and the sentence implies possession, use "its" (no apostrophe). For example, which is correct?

• The dog ate it's dinner.
• The dog ate its dinner.

If you change "it's" to "it is" the first sentence becomes "The dog ate it is dinner.", which is gibberish. Also the sentence implies that the dinner belongs to the dog. Therefore the second version, with no apostrophe, is correct.

Answer 2

The pronoun it is a personal pronoun. The possessive form is its. Example sentence:

The fledgling fell from the nest. The one overhead is its.
