Side-by-side comparison
| Dimension | Its | It’s |
|---|---|---|
| What it is | A possessive determiner (like his or her). | A contraction of "it is" or "it has". |
| Meaning | Belonging to it. | It is, or it has. |
| Has an apostrophe? | No — never. | Yes — the apostrophe marks the missing letter(s). |
| The test | Expanding to "it is/it has" breaks the sentence. | Expanding to "it is/it has" keeps the sentence correct. |
| Example | The company changed its logo. | It’s the best result so far. |
| Second example | Every theory has its limits. | It’s been raining all week. |
| Why the confusion | Most possessives use ’s, so writers add one by mistake. | Looks like a possessive but is actually a contraction. |
| Grammar class | Possessive form of the pronoun "it". | Pronoun + verb collapsed into one word. |
| Common error | Writing "it’s tail" for an animal’s tail. | Writing "its raining" when you mean it is raining. |
Why the apostrophe rule reverses here
For most nouns, an apostrophe plus s shows possession — the dog’s bone, the student’s essay. That habit is exactly what causes the its/it’s error, because the possessive of "it" breaks the pattern: it takes no apostrophe at all. Possessive pronouns as a group — its, his, hers, ours, yours, theirs, whose — never use an apostrophe. The apostrophe in it’s does only one job: it marks the missing letters in a contraction (it is → it’s, it has → it’s). So when you are unsure, mentally expand the word to "it is" or "it has". If the expansion reads correctly, the apostrophe belongs; if it does not, you want the bare possessive its.
Common questions
FAQ
What is the easiest way to choose its or it’s?+
Read the sentence with "it is" or "it has" in place of the word. If the sentence still makes sense — "it is raining" — write it’s with an apostrophe. If it does not make sense — "it is tail wagged" is nonsense — write its with no apostrophe. The test works every time because it’s only ever means it is or it has.
Does "it’s" ever mean possession?+
No. It’s with an apostrophe is always a contraction of it is or it has, never a possessive. Unlike a noun, where an apostrophe shows ownership, the pronoun it shows possession with the bare form its. So "the bird built it’s nest" is incorrect; it should be "its nest".
Is "its’" ever correct?+
No. The form "its’" with a trailing apostrophe does not exist in standard English. The only two valid spellings are its (possessive) and it’s (it is / it has). If you have written its’, you have one apostrophe too many.
