Common Confusions

It's vs Its

Quick Summary

It's (with apostrophe) = "it is" or "it has" (contraction). Its (no apostrophe) = possessive, meaning "belonging to it." Test: if you can replace it with "it is," use it's. Otherwise, use its.

Despite being one of the most common errors in English writing, the distinction between it's and its is actually quite simple. The confusion arises because we're used to apostrophes indicating possession (like "John's book"), but with its, the rule is different. This exception trips up even educated native speakers (Truss, 2003).

It's = It Is OR It Has (Contraction)

It's with an apostrophe is ALWAYS a contraction-a shortened form of "it is" or "it has." If you can expand it to "it is" or "it has," use the apostrophe.

It's raining. (It is raining)
It's been a long day. (It has been a long day)
I think it's time to go. (it is time)
It's never too late to learn. (It is never)
It's made from recycled materials. (It is made)

Its = Possessive (Belonging To It)

Its without an apostrophe is the possessive form, showing that something belongs to "it." Like other possessive pronouns (his, hers, yours, theirs), it doesn't use an apostrophe.

The dog wagged its tail. (the tail belonging to the dog)
The company announced its new policy. (the policy of the company)
The bird built its nest in the tree. (the nest belonging to the bird)
The book has lost its cover. (the cover of the book)
Every country has its own culture. (the culture belonging to each country)

Simple Test: Can You Replace It?

If you're unsure which to use, try this replacement test:

Replace with "it is" or "it has":
✅ If it makes sense → use IT'S
❌ If it doesn't make sense → use ITS

Example: "The cat licked _____ paws."

Remember: Possessive Pronouns Never Have Apostrophes

his (not hi's)
hers (not her's)
yours (not your's)
theirs (not their's)
its (not it's for possessive)

Common Mistakes

❌ The car lost it's wheel. → ✅ The car lost its wheel. (possessive)
❌ Its raining outside. → ✅ It's raining outside. (it is)
❌ The team celebrated it's victory. → ✅ The team celebrated its victory. (possessive)
❌ I think its broken. → ✅ I think it's broken. (it is)

Pro tip: When in doubt, expand the contraction in your head. If "it is" or "it has" makes sense in the sentence, use it's. Otherwise, use its.

Frequently Asked Questions

Why doesn't "its" have an apostrophe for possession?

Possessive pronouns (his, hers, yours, theirs, its) never use apostrophes. The apostrophe in "it's" is reserved for the contraction of "it is" or "it has."

Is "its'" ever correct?

No. "Its'" (with a trailing apostrophe) does not exist in English. Use its for possessive and it's for "it is" or "it has."
