Its Self or Itself

Its Self or Itself: helps you choose the correct form, avoid grammar mistakes, and keep everyday English clear, natural, and precise in your writing. Choosing between its self and itself becomes easier when you understand their grammatical roles. Itself is a reflexive pronoun that points back to the subject when the subject and object refer to the same thing. For example, the cat licked itself, where licked is a verb in the past simple and itself is the reflexive form. 

This example shows how parts of speech, including nouns, verbs, adjectives, adverbs, prepositions, conjunctions, and pronouns, work together. Like myself and yourself, itself is normally written as one word. In contrast, its is a possessive pronoun or determiner that shows ownership, as in a company that updated its policy. The two-word string its self is almost always incorrect in modern Standard English because the separate self can sound redundant or awkward when its already expresses possession.

When you write online, talk to someone about grammar, or see how people use these forms, the confusion becomes easier to understand step by step. A single space or missing letter may seem like a small detail, yet it can affect natural writing and make the meaning less clear. In modern English, itself is the standard choice, while its self appears mainly in rare cases or special contexts where self works as a separate noun. 

Contextual examples and example sentences can help you check verb tense, subject–verb agreement, and modifiers that modify other words. These checks also help writers and editors avoid common mistakes, including fragments and run-ons, in an email, essay, or professional document. The same basic rule applies in American English and British English, although broader differences may appear in some idiomatic uses. With a practical guide and regular practice, this tricky territory becomes less like solving a puzzle and more like recognizing a familiar pattern.

The goal is to choose the right form without second-guessing yourself. When it needs to point back to its subject, itself is usually the correct form, helping your writing stay clear, natural, and well understood. Its self is rarely correct, and using it unnecessarily can cause grammar mistakes, weaken sentence clarity, and create an unusual impression. Recognizing the correct form becomes easier when you understand how these terms fit into sentences rather than simply memorizing a rule. 

The two forms look similar and may sound alike, so they can confuse native speakers as well as learners. However, their grammatical functions aren’t identical. Understanding this subtle difference helps you stop mixing up the forms and improve your writing style. With confidence, you can learn to use these forms correctly in everyday writing, whether you are preparing a message, explaining an idea, or checking a sentence for clarity. The result is a more precise message that communicates exactly what you mean without an embarrassing grammar mistake.

Quick Summary

Itself is the standard reflexive pronoun used when it refers back to the same subject or object. Its self is almost always incorrect in modern Standard English. Use itself as one word in everyday writing, emails, essays, and professional documents.

Its Self or Itself: The Quick Answer

Let’s start with the most important point.

• Itself is a reflexive pronoun.
• Its is a possessive determiner.
• Its self is not standard in modern everyday English.

Use itself when the subject and object refer to the same thing.

Examples:

• The cat cleaned itself.
• The company is protecting itself from fraud.
• The machine shuts down by itself.

Use its when you need to show possession.

Examples:

• The robot lost its battery cover.
• The tree dropped its leaves.
• The app updated its settings.

So, if you are deciding between its self or itself, choose itself almost every time.

What “Its” Means

The word its shows possession. It tells you that something belongs to it.

Think of it like his, her, or their, but for a thing, animal, or idea.

Examples:

• The dog wagged its tail.
• The car lost its mirror.
• The school changed its policy.
• The planet has its own orbit.

Notice something important: its does not use an apostrophe.

That is a major reason people make mistakes. Many writers assume apostrophes show possession in every case. Usually, that is true for nouns. But its is an exception.

Compare:

• The child forgot his book.
• The girl found her bag.
• The company changed its logo.

All three words show ownership. None of them need an apostrophe.

A simple memory trick

If you can replace the word with his or her, then its is probably correct.

• The phone lost its charger.
  The phone lost his/her charger.
  That sounds wrong with people, but the grammar idea is the same: it shows possession.

What “Itself” Means

Itself is a reflexive pronoun. That means it refers back to the subject of the sentence.

In plain English, the thing doing the action and the thing receiving the action are the same.

Examples:

• The baby entertained itself.
• The car repaired itself after the reset.
• The door locked itself.
• The system shut itself down.

You use itself when:

• the subject and object are the same
• you want to add emphasis
• you want to show an action happening without outside help

Reflexive use

This is the most common use.

• The drone calibrated itself.
• The software updated itself overnight.
• The lamp switched itself off.

Emphatic use

Sometimes itself adds emphasis.

• The museum itself was closed.
• The engine itself is not the problem.
• The policy itself is fair, but the timing is bad.

In these sentences, itself draws attention to the subject.

Why People Write “Its Self”

The mistake usually happens for three reasons.

Spacing confusion

Some writers see its and think the word self should be separate.

That feels logical, but standard English does not usually split them that way.

• Incorrect: The dog cleaned its self.
• Correct: The dog cleaned itself.

Possessive confusion

People often know that its shows possession. Then they try to add self after it because they want to show “own self.”

That is not how standard English works.

• Incorrect: The machine reset its self.
• Correct: The machine reset itself.

Analogy with other reflexive forms

English has forms like:

• myself
• yourself
• himself
• herself
• ourselves
• themselves

Because these are written as one word, learners sometimes expect it self to follow the same pattern. The correct standard form does. It is itself, one word, not two.

Its Self vs Itself: Side-by-Side Comparison

Form	Part of Speech	Meaning	Correct?	Example
its	Possessive determiner	Belonging to it	Yes	The cat licked its paw.
itself	Reflexive pronoun	The same thing acting on or emphasizing itself	Yes	The cat licked itself.
its self	Not standard in modern everyday English	A separated form that is usually a mistake	Usually no	The cat licked its self.

This table gives the core rule in one place.

If the word shows possession, use its.
If the word refers back to the subject, use itself.
If you write its self, it will usually look incorrect.

When to Use Itself Correctly

Use itself in these common situations.

When something acts on itself

• The car parked itself.
• The seed planted itself in soft soil.
• The software restarted itself after the crash.

When something is the same subject and object

• The child dressed itself in the game.
• The cat hurt itself while jumping.
• The drone landed itself on the pad.

When you want emphasis

• The building itself is historic.
• The idea itself is not bad.
• The phone itself is fine, but the battery is weak.

When a process happens automatically

• The machine turns itself off after ten minutes.
• The app logs itself out for security.
• The heater regulates itself based on temperature.

These uses cover most of the real-world cases you will see.

When “Its Self” Appears

Here is where things get a little more interesting.

In standard modern English, its self is usually not the right form. Still, you may occasionally see phrases that look similar in older writing, philosophical writing, or poetic writing.

For example, someone may write:

• the thing in its own self
• the creature in its true self
• the spirit as its self

These are not the same as the everyday grammar form itself. They often sound literary, abstract, or stylized.

In normal writing, especially if you are writing for school, blogging, business, or daily communication, stick to itself.

That rule keeps your writing clean and safe.

The Difference Between Its, It’s, and Itself

This is one of the biggest traps in English.

Its

Use its for possession.

• The bird lost its nest.
• The phone lost its charger.

It’s

Use it’s only as a contraction for it is or it has.

• It’s raining. = It is raining.
• It’s been a long day. = It has been a long day.

Itself

Use itself when the thing refers back to itself.

• The robot fixed itself.
• The company promoted itself online.

Quick comparison

Word	Meaning	Example
its	belonging to it	The dog wagged its tail.
it’s	it is / it has	It’s cold today.
itself	the same thing, reflexive	The dog washed itself.

If you remember only one thing, remember this:

• its = possession
• it’s = it is / it has
• itself = reflexive or emphatic

That trio solves most mistakes.

Examples of Its Self or Itself in Real Sentences

Below are clear examples showing the correct form.

Correct examples with itself

• The bird cleaned itself after the rain.
• The phone shut itself off.
• The organization protected itself with better policies.
• The garden watered itself through the automatic system.
• The cat found itself trapped under the chair.

Correct examples with its

• The bird spread its wings.
• The phone charged its battery.
• The organization changed its rules.
• The garden lost its color in winter.
• The cat injured its paw.

Incorrect examples with its self

• The bird cleaned its self. ❌
• The phone shut its self off. ❌
• The organization protected its self. ❌
• The garden watered its self. ❌
• The cat found its self trapped. ❌

That is why its self or itself is not a close contest in standard English. Itself wins almost every time.

Common Mistakes Learners Make

English learners usually make the same few mistakes with this topic.

Mixing up possession and reflexive form

This is the most common problem.

Wrong:

• The dog chased its self.

Right:

• The dog chased itself.

Why? Because the dog is both the subject and the object.

Adding an apostrophe to its

Wrong:

• The dog wagged it’s tail.

Right:

• The dog wagged its tail.

Why? Because it’s means it is or it has, not possession.

Separating itself into two words

Wrong:

• The machine repaired it self.

Right:

• The machine repaired itself.

Why? Because the correct standard reflexive pronoun is one word.

Using itself when possession is needed

Wrong:

• The cat cleaned itself paw.

Right:

• The cat cleaned its paw.

Why? Because paw belongs to the cat. That calls for possession.

A Simple Test to Choose the Right Word

Here is a quick test you can use while writing.

Test for possession

Ask: Does the word show ownership?

• Yes → use its
• No → move to the next test

Example:

• The laptop lost its charger.

Does the charger belong to the laptop? Yes. So its is right.

Test for reflexive action

Ask: Is the subject acting on itself?

• Yes → use itself
• No → use another form

Example:

• The machine reset itself.

The machine did the action, and the result affected the machine. So itself is right.

Test for emphasis

Ask: Do I want to stress the noun?

• Yes → itself may work

Example:

• The car itself is not the problem.

This sentence emphasizes the car, not the engine or the road.

Mini Case Studies

A few short case studies make the rule easier to remember.

Case study: The smart thermostat

Sentence:

• The thermostat adjusted itself overnight.

Why this is correct:
The thermostat made the adjustment automatically. It is both the subject and the object of the action.

Now compare:

• The thermostat lost its settings.

Why this is correct:
The settings belong to the thermostat. That is possession.

Case study: The school website

Sentence:

• The school updated its website.

Why this is correct:
The website belongs to the school.

Now compare:

• The school website refreshed itself after the update.

Why this is correct:
The website performed an automatic action or was refreshed without manual help.

Case study: The dog in the story

Sentence:

• The dog scratched itself behind the ear.

Why this is correct:
The dog did the scratching and received the action.

Now compare:

• The dog chased its tail.

Why this is correct:
The tail belongs to the dog.

These examples show the pattern clearly. Possession needs its. Reflexive action needs itself.

Grammar Rule You Can Trust

Here is the practical rule in one sentence:

Use “its” for possession and “itself” for reflexive or emphatic meaning.

That rule works in everyday writing, school writing, blogging, editing, and professional content.

It also helps you avoid a common trap: trying to split itself into its self.

In standard English, that split is almost always wrong.

A Few More Examples for Practice

Try reading these and noticing why each one uses its or itself.

• The robot cleaned itself after the test.
• The robot lost its instruction manual.
• The truck parked itself in the garage.
• The truck needed its tires replaced.
• The cat licked itself.
• The cat found its bowl empty.
• The app updated itself.
• The app changed its layout.

When you see the pattern enough times, it starts to feel automatic.

Quick Reference Cheat Sheet

Use this mini guide when you write.

Choose its when:

• you mean possession
• something belongs to it
• you can replace the idea with his, her, or their in structure

Examples:

• its color
• its engine
• its design
• its name

Choose itself when:

• the subject and object are the same
• the action returns to the subject
• you want emphasis

Examples:

• fixed itself
• protected itself
• the building itself
• the idea itself

Avoid its self unless:

• you are intentionally writing in a rare stylistic or philosophical way
• the context clearly calls for a nonstandard or literary phrase

For almost all readers, that is not the right choice.

Quotes That Capture the Idea

A good grammar rule often becomes easier when stated simply.

Possession needs “its.” Reflexive action needs “itself.”

If the subject and object are the same, “itself” is usually the answer.

These are not fancy rules. They are plain and useful. That is exactly why they work.

FAQs

Is “Its Self” or “Itself” correct?

Itself is the correct standard spelling. Its self is generally incorrect when you mean the reflexive pronoun.

What does “itself” mean?

Itself is a reflexive pronoun used to refer back to a singular thing, animal, or organization. For example, “The machine turned itself off.”

Why is “its self” usually incorrect?

Its self separates the possessive determiner its from the noun self. In most sentences, English uses the single-word reflexive pronoun itself instead.

Can “its self” ever be correct?

Yes, but only in unusual contexts where self is being used as a separate noun. For example, “The company returned to its self after the crisis” could be used in a highly specific or philosophical context, but it isn’t the normal grammatical construction.

Is “it’s self” correct?

No. It’s means it is or it has, so it’s self is not the standard reflexive form. The correct word is itself.

What is the difference between “its” and “itself”?

Its shows possession, while itself works as a reflexive or emphatic pronoun. For example, “The dog wagged its tail” uses possession, while “The dog opened the door itself” uses a reflexive pronoun.

Conclusion

Itself is the correct spelling when you need the reflexive pronoun referring to a singular thing, animal, or organization. 

Its self is normally incorrect in everyday English, while it’s self is also incorrect because it’s means “it is” or “it has.” When you’re unsure, remember the simple rule: use itself as one word.
