"Its" vs "It's": The Apostrophe Rule Students Keep Missing
Its vs it's — the possessive-without-apostrophe rule, why it's confusing, and how to never mix them up again.
Even native speakers mix these up. “The dog wagged it’s tail.” “Its a nice day.” These errors are everywhere — in emails, on signs, in published articles.
The reason it’s confusing: in English, apostrophe + s usually means possessive (John’s book, the cat’s tail). But “its” breaks this rule — the possessive has no apostrophe.
Normally:
- Apostrophe + s = possessive: John’s book, the dog’s tail, India’s capital
- But: its tail (no apostrophe), his car (no apostrophe), her book (no apostrophe)
The reason “it’s” has an apostrophe is that it is a contraction, not a possessive. “It’s” = “it is” or “it has.” The apostrophe replaces the missing letter(s).
Replace with “it is” or “it has”:
- If the sentence still makes sense → use it’s.
- If it becomes nonsense → use its.
It’s raining. = It is raining. ✓ → it’s
The dog wagged its tail. = The dog wagged it is tail. ✗ → its
It’s been a long day. = It has been a long day. ✓ → it’s
The company changed its policy. = The company changed it is policy. ✗ → its
“It’s” only ever means one of two things:
- It is: “It’s cold today.” “It’s time to go.”
- It has: “It’s been a great year.” “It’s already started.”
That’s all. If you cannot replace “it’s” with “it is” or “it has,” you are using it wrong.
“Its” shows that something belongs to “it”:
The cat licked its paws.
The tree lost its leaves.
The government announced its new policy.
Every country has its own culture.
“Its” works exactly like “his,” “her,” “our,” and “their” — all possessive pronouns with no apostrophe.
| Incorrect | Correct | Why |
|---|---|---|
| The dog wagged it’s tail. | The dog wagged its tail. | Possessive, not contraction |
| Its a beautiful day. | It’s a beautiful day. | = It is a beautiful day |
| The tree lost it’s leaves. | The tree lost its leaves. | Possessive |
| Its been great. | It’s been great. | = It has been great |
- _____ going to rain later.
- The company changed _____ logo.
- _____ been a pleasure meeting you.
- The cat cleaned _____ fur.
- _____ not too late to start.
- It’s (= It is)
- its (possessive — the logo belongs to the company)
- It’s (= It has)
- its (possessive — the fur belongs to the cat)
- It’s (= It is)
- It’s = it is / it has (contraction — apostrophe replaces missing letter)
- Its = possessive (belonging to it — no apostrophe)
- The substitution test never fails: try replacing with “it is” or “it has.”
