Its vs It'S: What's the Difference?

Its vs It's: What's the Difference?

Quick Answer

Use its when showing possession (the dog wagged its tail); use it's as a contraction for it is or it has (it's cold; it's been a long day).

Definition of "Its"

"Its" is a possessive pronoun that shows ownership or association without using an apostrophe. Think of it the same way you use his or her, but gender-neutral and for things, animals, or concepts.

The word comes from Middle English, originally from Old English "hit" (it) plus the genitive ending. Unlike most possessives, English dropped the apostrophe for this one early on to avoid confusion with contractions.

Definition of "It's"

"It's" is a contraction that combines it + is or it + has. The apostrophe replaces the missing letter(s), so it's = it is or it's = it has (usually when followed by a past participle).

Contractions became common in Early Modern English as a way to reflect spoken language in writing, and the apostrophe marks the omission. Remember: an apostrophe signals something's been left out.

Key Differences

Example Sentences — "its"

• The laptop lost its charge after three hours of streaming.
• Every country has its own customs and holidays.
• The tree shed its leaves in a single windy night.
• Make sure the robot completes its task before you shut it down.

Example Sentences — "it's"

• It's a beautiful day for a walk along the river. (it is)
• Don't worry—it's already been fixed. (it has)
• It's been ages since we last spoke. (it has)
• If it's not raining, we'll eat outside. (it is)

Simple Tests You Can Use Right Now

When in doubt, try expanding "it's" to "it is" or "it has." If the sentence still makes sense, use it's. If not, use its.

Another quick check: replace the word with "his" or "her." If that replacement makes sense, the possessive its is likely correct.

Memory Trick

Think: the apostrophe is a little "i" for "is" (or "has"). If you can mentally expand the apostrophe into "is" or "has," keep the apostrophe. If expansion doesn't work, don't add one.

Short mnemonic: "It's = it is/has; Its = belongs to it." Repeat it once and your brain will file it away where grammar lives.

Frequently Asked Questions

Can "it's" ever be possessive?

No. "It's" is only a contraction of "it is" or "it has." The possessive form is its without an apostrophe.

How can I remember not to add an apostrophe to "its"?

Use the expansion test: if you can replace the word with "it is" or "it has," use it's. If you mean ownership, use its. A quick trick: apostrophes show missing letters, not possession in this case.
