If you’re wondering whether to write its self or itself, you’re not alone. This is a very common confusion but the correct choice is simple once you understand the rule.
Quick Answer
- Itself ✅ correct
- Its self ❌ incorrect (in standard usage)
👉 In short:
Always use “itself.”
What Does “Itself” Mean?
Itself is a reflexive pronoun. It refers back to a subject (usually a thing or animal) to show that the action affects the same thing.
Common Uses of Itself
- Emphasizing something
- Showing self-action
- Referring back to the subject
Examples of Itself
- The cat cleaned itself.
- The machine shut down by itself.
- The problem will solve itself.
👉 It connects the subject and the action clearly.
Why “Its Self” Is Incorrect
Its self (two words) is not standard English. It’s a mistaken split of the correct word itself.
❌ Incorrect: The device fixed its self.
✅ Correct: The device fixed itself.
What About “Its” vs “It’s”?
While learning this, it helps to remember:
- Its → possessive (belongs to it)
- It’s → contraction of it is or it has
Examples
- The dog wagged its tail.
- It’s going to rain.
👉 But for reflexive use, always choose itself.
