English contains so many confusing words and punctuation marks you’d be forgiven for imagining some diabolical grammarian put them there to torture us. You’d be wrong, but it’s a reasonable assumption. One confusing pair that unites tricky words with slippery punctuation is its and it’s. This confusion is exacerbated by the fact that its is one of the top 100 most frequently used words in English. It appears all the time—giving us oodles of opportunities for error.
That’s right: its vs. it’s
Yet the two rules are actually quite easy to remember.
Rule 1: When you mean it is or it has, use an apostrophe.
It’s a nice day.
It’s your right to refuse the invitation.
It’s been great getting to know you.
Rule 2: When you are using its as a possessive, don’t use the apostrophe.
The cat hurt its paw.
The furniture store celebrated its tenth anniversary.
