Option A

Its

Possessive pronoun

Showing that something belongs to 'it.' No apostrophe.

Examples
  • "The dog wagged its tail."
  • "The company changed its policy."
  • "Each book has its own theme."
Option B

It's

Contraction

Short for 'it is' or 'it has.' Apostrophe replaces the missing letter(s).

Examples
  • "It's raining outside (it is)."
  • "It's been a long day (it has)."
  • "I think it's a great idea (it is)."

Why Are They Confused?

Apostrophes usually indicate possession (the dog's tail). With 'its,' English breaks its own rule — the possessive form has NO apostrophe. The apostrophe is reserved for the contraction. This is why it's the most-confused pair in English.

💡 Memory Trick

If you can replace the word with 'it is' or 'it has,' use it's (with apostrophe). If not, use its (no apostrophe). Always test by expanding the contraction.
