Its or It’s | Difference & Example Sentences

Though they’re pronounced the same, there’s a big difference in meaning between its and it’s.

  • Its (without an apostrophe) is the possessive form of it, so it means ‘belonging to it’.
  • Its’ (apostrophe after the ‘s’) is not actually a word, even though people sometimes mistakenly use it in place of its.
Examples: ‘Its’ in a sentence Examples: ‘It’s’ in a sentence
The dog chased its tail. It’s almost two o’clock.

Its: Possessive determiner

Its is a possessive determiner like ‘his’ or ‘her’. It is formed from the neuter singular pronoun ‘it’. While possession is usually indicated by adding ’s to the end of the word, possessive determiners formed from personal pronouns don’t use an apostrophe in the possessive form: I/my, he/his, she/her, it/its.

Be extra careful when typing ‘its’. Spell checkers will sometimes mistake your meaning and insert an apostrophe where none is needed, so make sure to check yourself.

Examples: Possessive determiner ‘its’
The house used to be nice, but it lost its charm when it was renovated.

It’s: Contraction

It’s can be used as a contraction of it is or it has. It’s never used in place of it was, though.

Example: ‘It is’ or ‘it has’
It’s (it is) about quality, not quantity.

It’s (it has) been two months since I applied for the research grant.

Although contractions are fine in informal writing, you should avoid contractions in formal or academic writing. So you’ll never write it’s in an academic text.

Tip
If you’re unsure whether you’re using it’s correctly, replace it with it is or it has:

  • If the sentence makes sense with one of these substitutions, then it’s is the correct word to use.
  • If not, you probably mean its.
