Common Grammar Mistake: "It's" vs "Its"

One of the most common grammar mistakes people make is confusing "it's" and "its." While they may sound similar, these words have different meanings and uses. Let's take a closer look at the correct usage of each.

1. "It's" - The Contraction

"It's" is a contraction that means "it is" or "it has." It is formed by combining the pronoun "it" with the verb "is" or "has" and should be used when referring to something that possesses or performs an action.


  • It's a beautiful day outside.
  • It's been a long day at work.
  • I can't believe it's already time to go.

2. "Its" - The Possessive Pronoun

"Its" is a possessive pronoun that indicates ownership or possession. It is equivalent to the pronouns "his" or "hers" and does not require an apostrophe. This is a mistake that even seasoned writers may make.


  • The dog wagged its tail.
  • The company is known for its innovative products.
  • The tree lost its leaves in the autumn.

It's important to note that "it's" is always a contraction, while "its" is always a possessive pronoun. Mixing them up can lead to confusion and affect the clarity of your writing.
