Quick Answer: Is It “Its Self” or “Itself”?
Itself is usually the correct form when you need the reflexive pronoun related to it. The word itself is written as one word, not “its self,” in ordinary modern English. For example, “The computer restarted itself” means the computer restarted without someone directly restarting it. By contrast, its shows possession, as in “The computer lost its connection.” The separate phrase itself can occasionally appear when self acts as a noun, and its modifies that noun, but this use is uncommon and usually depends on a specialized context. So, if you’re wondering whether to write “The machine fixed its self” or “The machine fixed itself,” choose itself. The key is to look at the grammatical job of the word rather than how the phrase sounds when spoken.
The Correct Form in Modern English
In everyday writing, itself is the standard form. English treats it as a single reflexive pronoun, just like myself, yourself, himself, herself, and themselves. When it acts as the subject and the same thing receives the action, itself usually completes the sentence. Consider “The door closed itself” or “The software updated itself.” In both examples, the noun performs or experiences the action, then itself points back to that same noun. Writing “its self” in these sentences would break the normal sentence structure and create an incorrect reflexive construction. A useful editing habit is to identify the subject first. If it represents the thing involved in the action and you need a word that refers back to it, itself is the natural choice.
Why “Itself” Is Usually the Right Choice
The simplest way to understand itself is to connect it directly with it. If a singular object, animal, organization, system, or idea acts on the same entity, English commonly uses itself. For example, “The cat cleaned itself” uses a reflexive construction because the cat performs the action and receives it. Likewise, “The program corrected itself” tells you that the program corrected without another subject performing that action. However, itself can also add emphasis. In “The problem itself isn’t difficult,” the word doesn’t describe an action directed back at the problem. Instead, it emphasizes the noun. This distinction matters because itself has more than one grammatical use. Once you recognize whether you’re showing reflexive action or adding emphasis, choosing the correct form becomes much easier.
When “Its Self” May Occasionally Appear
Although its self isn’t the normal replacement for itself, the two words can appear separately in unusual contexts. Here, its functions as a possessive determiner and self functions as a noun. The phrase may occur when a writer discusses an entity’s particular identity, nature, or essential character. Such wording often appears in philosophical, literary, or highly specialized discussions rather than ordinary conversation. For example, a writer might discuss something returning to “its self” in a deliberately abstract context. That doesn’t make its self an alternative spelling of itself. The grammatical roles remain different. In practical writing, especially emails, school assignments, websites, reports, and everyday communication, itself will almost always be the form you need when the meaning is reflexive. If you can replace the phrase with “it” referring back to the same thing, itself is generally the better choice.
What Does “Itself” Mean in English Grammar?
At its core, itself refers back to a singular it. It belongs to the group of reflexive pronouns that point toward an earlier noun or pronoun in a sentence. That earlier word is called the antecedent. In “The machine repaired itself,” for instance, “machine” provides the reference for itself. The pronoun doesn’t introduce a new object. Instead, it sends the reader back to the noun already established in the sentence. This relationship makes itself useful when you want to show that the subject and the affected entity are the same. However, context still matters. You shouldn’t add itself simply because a sentence contains it. First, check what role the word needs to play. That small distinction can prevent many common grammar errors.
Definition of “Itself”
Itself is a singular reflexive and emphatic pronoun associated with it. Writers use it when a nonhuman or grammatically neuter antecedent refers back to itself. Depending on the sentence, it can show reflexive action or provide emphasis. For example, “The robot moved itself across the room” shows reflexive action. The robot performs the movement and refers back to itself. Meanwhile, “The robot itself made the decision” emphasizes the robot. The word looks identical in both sentences, but its grammatical function changes. This is why memorizing one fixed definition isn’t enough. Pay attention to the relationship between the subject, verb, and surrounding words. Once you see that pattern, it becomes much more predictable.
“Itself” as a Reflexive Pronoun
A reflexive pronoun refers back to the subject of a clause when the subject and object represent the same entity. With itself, that subject is normally represented by it or by a singular noun that takes it as its corresponding pronoun. “The device damaged itself” provides a clear example. The device causes the damage, and the device receives the action. You can picture the action as a loop that returns to its starting point. That’s the central idea behind reflexive grammar. Other pronouns follow the same pattern: “She blamed herself” and “They prepared themselves.” The form changes according to the subject, but the grammatical relationship stays consistent.
How Reflexive Pronouns Work in English Grammar
Reflexive pronouns become easier when you focus on who performs an action and who receives it. Start with the subject. Then identify the object. If both refer to the same entity, a reflexive pronoun may be necessary. For example, “The system restarted itself” contains “system” as the subject and itself as the reflexive object. The action returns to the system. However, “The technician restarted the system” doesn’t need itself because the technician and system are different entities. This subject-object relationship is one of the most reliable ways to choose the correct form. When you slow down and trace the action through the sentence, the difference becomes clear without relying on guesswork.
What Does “Self” Mean?
While itself works as a reflexive or emphatic pronoun, self usually works as a noun. It can refer to a person’s identity, character, nature, or sense of who they are. You might see it in phrases such as “sense of self,” “self-image,” or “self-awareness.” In these expressions, self doesn’t point back to a subject in the same way that itself does. Instead, it names an idea or aspect of identity. That difference explains why you can’t normally swap self for itself. For example, “The machine repaired itself” describes an action that returns to the machine. “The self develops through experience” discusses identity as a concept. The two words may look closely related, but their grammatical jobs aren’t the same.
“Self” as a Noun
When self appears as a noun, it often describes an individual’s identity or essential nature. The expression the self can refer to the person as a whole, especially in discussions about identity, behavior, or personal development. For example, “A person’s sense of self can change over time” treats self as a noun. You can also find the word in everyday phrases such as “be yourself,” although yourself functions differently in that construction. Context makes the distinction clear. If you’re naming or discussing identity, self may be the word you need. If you’re showing that an action returns to a singular thing, itself usually fits instead. Keeping that grammatical difference in mind makes these forms much easier to separate.
“Self” in Compound Words
The word self also appears in many common compound words. These include self-care, self-confidence, self-control, self-awareness, and self-service. In each case, self- contributes an idea connected with the person or thing itself. However, these compounds don’t turn self into a reflexive pronoun. For example, “She showed strong self-control” doesn’t mean the same thing as “She controlled herself.” The first sentence uses a compound noun. The second uses a reflexive pronoun. This distinction becomes especially useful when you’re editing formal writing because compound words can make self look similar to the forms ending in -self. Look at the complete word and its role in the sentence before deciding what it means.
“Self” When Referring to Identity or Nature
When writers discuss identity, personality, or essential nature, self can carry a broader meaning. A sentence such as “The experience changed his sense of self” focuses on identity rather than physical action. Likewise, “The artist wanted the work to reflect her true self” uses self as a noun. These examples don’t need itself because no reflexive action occurs. Instead, the word refers to an individual’s inner identity or character. You can think of self as a name for the person or identity being discussed. Itself, on the other hand, usually points back to something already named. That small shift in grammatical function explains why the two forms shouldn’t be treated as interchangeable.
“Self” vs. Reflexive Pronouns
English reflexive pronouns include myself, yourself, himself, herself, itself, ourselves, and themselves. Although each contains self or selves, the complete form functions as a pronoun. The standalone word self normally functions as a noun. Compare “The child hurt himself” with “The child developed a stronger sense of self.” In the first sentence, himself refers back to the child and completes a reflexive construction. In the second, self names an aspect of identity. The shared word doesn’t make their grammatical roles identical. Instead, the surrounding structure tells you which meaning the sentence needs.
Is “Its Self” Ever Correct?
Yes, its self can appear as two separate words, but this isn’t simply another spelling of itself. The distinction comes from grammar. Its acts as a possessive determiner while self acts as a noun. In ordinary modern English, writers rarely need this combination. Most sentences that seem to call for “its self” actually require itself. For example, “The machine repaired itself” needs the reflexive pronoun because the machine performs the action and receives it. Separating the word would change the construction. The phrase its self may appear in specialized philosophical, literary, or abstract writing where a writer deliberately treats “self” as a noun belonging to something. That’s a different grammatical situation. So, don’t use “its self” simply because you think itself should be written as two words.
When “Its Self” Appears as Two Separate Words
The phrase its self consists of two independent words with separate grammatical functions. Its tells you that something possesses or relates to the following noun. Self then acts as that noun. This construction can appear when a writer discusses an entity’s identity or essential nature as something conceptually distinct. For instance, specialized prose might describe an object in relation to “its self” when the writer wants to discuss the object’s identity abstractly. Such examples don’t represent ordinary reflexive grammar. In everyday writing, “The device adjusted itself” remains the natural choice. A useful test is to ask whether self truly acts as a noun in the sentence. If it doesn’t, you probably need the single word itself.
“Its” as a Possessive Determiner
Its shows possession or association. It normally appears before a noun, as in “The company changed its policy” or “The dog wagged its tail.” Here, its tells the reader who or what the noun belongs to. That role differs sharply from itself, which refers back to an antecedent in a reflexive or emphatic construction. This difference becomes obvious when you compare “The system updated its settings” with “The system updated itself.” In the first sentence, the system possesses the settings. In the second, the system receives the action. The spelling may look similar, but the grammar points in two different directions. Remembering this distinction can help you avoid one of the most common errors involving its and itself.
“Self” as the Noun Being Modified
When self follows its, the phrase treats self as a noun that receives a possessive modifier. That structure is possible in English, but it isn’t the normal way to express reflexive action. Consider the difference between “The machine repaired itself” and a specialized phrase discussing “the machine’s self.” The first sentence describes an action. The second treats self as a concept or identity. Adding its before self creates another layer of meaning because the writer presents that self as belonging to an entity. This construction can sound unusual in everyday English. That’s why readers may initially assume it’s an error. In most practical situations, however, the single-word form itself communicates the intended meaning more clearly.
Why “Its Self” Is Rare in Everyday English
Everyday English favors direct, familiar constructions. When a writer wants to show that something acts on itself, itself does the job cleanly. There’s rarely a reason to separate the form into its self. You might encounter the two-word phrase in philosophical discussion, literary analysis, or deliberately abstract prose. Even then, the writer usually has a specific reason for treating self as a noun. For ordinary emails, school assignments, articles, reports, and business communication, itself is almost always the better choice when the meaning is reflexive. This isn’t just a spelling preference. It reflects the grammatical role of the word in the sentence.
Philosophical and Literary Uses of “Its Self”
In philosophical or literary writing, self can represent identity, essence, or the nature of an entity. A writer may therefore use its self when discussing that identity as a separate noun. The wording can sound more abstract than everyday English because the writer isn’t describing a simple reflexive action. Instead, the phrase may explore what something is in relation to its own identity or nature. This specialized use shouldn’t confuse you when you’re writing ordinary sentences. If your meaning is simply that something acts on itself, use itself. If the sentence deliberately treats self as a noun and its modifies that noun, the two-word form may make sense. Context remains the deciding factor.
“Itself” vs. “Its Self”: Side-by-Side Comparison
The easiest way to see the difference is to compare their grammatical roles directly.
| Form | Grammatical Role | Main Function | Example |
| itself | Reflexive or emphatic pronoun | Refers back to a singular antecedent | The device repaired itself. |
| its | Possessive determiner | Shows possession or association | The device changed its settings. |
| its self | Possessive determiner + noun | Refers to a particular self or identity | The writer discussed the object in relation to itself. |
“Itself” vs. “Its Self” Examples
Consider these two structures carefully. “The robot repaired itself” uses itself as a reflexive pronoun. The robot acts and receives that action. In contrast, a sentence discussing “the robot’s self” treats self as a noun connected with identity. If a writer uses its self, the phrase must preserve that noun-based meaning. The distinction may seem tiny on the page, yet it changes the entire grammatical structure. When you encounter the choice during editing, don’t focus only on the space between the words. Ask what the sentence actually means. That approach reveals whether you need a reflexive pronoun or a possessive determiner followed by a noun.
Why Spacing Changes the Grammar
A space can sometimes signal more than a spelling difference. With itself, the complete word functions as one pronoun. With itself, its and self operate separately. That means the reader interprets the sentence differently. “The system monitored itself” contains one reflexive pronoun. “The system examined itself” would require self to function independently as a noun. Because that second structure carries a specialized meaning, it rarely belongs in ordinary writing. If you’re unsure, check whether the sentence describes an action directed back toward the subject. If it does, the single-word itself is generally the correct form.
How Context Determines the Correct Form
Grammar provides the rule, but context tells you how the writer intends the word to function. Look at the verb first, then identify the subject and object. If the subject and object refer to the same entity, itself may be required. If the sentence discusses identity or treats self as a noun, a different structure may work. For example, “The company defended itself” describes a reflexive relationship. “The company changed its image” expresses possession. A specialized sentence about an organization’s “self” could discuss identity instead. Reading the complete sentence prevents you from making a choice based only on pronunciation or appearance.
“Itself” vs. “Its” vs. “It’s”
These three forms often confuse because they look and sound related. Their functions, however, are completely different. Itself is a reflexive or emphatic pronoun. Its is a possessive determiner. It’s is a contraction meaning it is or it has. Compare “The computer fixed itself,” “The computer lost its connection,” and “It’s working again.” Each sentence uses a different form because each sentence expresses a different grammatical relationship. Once you identify the function, the spelling usually becomes obvious.
Itself: Reflexive and Emphatic Pronoun
Use itself when it refers back to a singular antecedent or adds emphasis to that antecedent. “The program installed itself” shows reflexive action. “The program itself caused the problem” uses emphasis. In both cases, itself remains a single word. The surrounding sentence determines whether it reflects an action or highlights a noun. This makes itself different from its, which normally appears before a noun to show possession.
Its: Possessive Determiner
Use its when you need to show that something belongs to or relates to it. For example, “The company updated its website” tells you that the website belongs to or is associated with the company. You don’t use its to show reflexive action. “The company updated its” would leave the sentence incomplete because its normally needs a following noun in this type of construction. If you mean that the company updated itself, write “The company updated itself.” The difference becomes easy once you ask whether you’re expressing possession or reflexive action.
It’s: “It Is” or “It Has”
It’s contains an apostrophe because it combines it with is or has. You can test it by replacing it’s with “it is” or “it has.” For example, “It’s ready” becomes “It is ready.” Likewise, “It’s been repaired” becomes “It has been repaired.” Neither meaning works in “The machine repaired itself,” so itself is required there. This substitution test works quickly and reliably. If “it is” or “it has” makes sense, choose it’s. If the word refers back to the subject, choose itself instead.
Easy Examples to Compare All Three
Look at these examples together:
- The device repaired itself.
- The device lost its power.
- It’s working normally now.
The first sentence uses a reflexive pronoun. The second shows possession or association. The third uses a contraction. These forms aren’t interchangeable even though they share the letters it. Once you recognize their individual roles, you can spot the correct choice almost instantly. That simple habit is especially useful when proofreading quickly because the three forms often appear close together in technical and everyday writing.
Common Mistakes With “Itself” and “Its Self”
Small spelling differences can create surprisingly large grammar problems. Itself and its self look closely related, yet they perform different jobs. The most common mistake involves adding a space to itself when the sentence needs a reflexive pronoun. Another frequent error involves confusing itself with its or it’s. These mistakes become easier to catch once you focus on function instead of appearance. Ask what the word does in the sentence. Does it refer back to the subject? Does it show possession? Does it mean “it is” or “it has”? Those questions quickly narrow down the correct choice. A careful writer also checks whether itself has a clear antecedent because a reflexive pronoun needs an understandable reference.
Writing “Its Self” Instead of “Itself”
One of the easiest errors to make is writing its self when you mean itself. For example, “The application installed its self” is incorrect in standard everyday English. The correct sentence is “The application installed itself.” Here, the application acts and receives. The reflexive pronoun must therefore appear as one word. This mistake often happens because writers hear the word as separate sounds. However, pronunciation doesn’t determine spelling. When itself refers back to the subject, keep the entire pronoun together. That simple rule works in most ordinary writing situations.
Confusing “Itself” With “Its”
The forms itself and its express different relationships. Its normally introduces a noun that belongs to or relates to something. For example, “The company changed its policy” shows possession or association. Itself, however, refers back to the company when the company performs an action involving itself. Compare “The company changed its policy” with “The company defended itself.” The first sentence contains a possessive determiner. The second contains a reflexive pronoun. If you identify what comes after the word, the distinction often becomes obvious. It usually connects to a noun, while itself can complete a reflexive construction.
Confusing “Itself” With “It’s”
The apostrophe in it’s creates another common trap. It’s means “it is” or “it has,” while itself doesn’t express either meaning. Try expanding the contraction when you’re unsure. If “it is” fits, use it’s. If “it has” fits, it’s may also be correct. For example, “It’s ready” means “It is ready.” Meanwhile, “The device repaired itself” needs the reflexive pronoun because the device receives its own action. The two forms may look similar at a glance, but their grammatical roles have nothing in common.
Using the Wrong Reflexive Pronoun
Reflexive pronouns must agree with the person or thing they refer to. A singular it takes itself, not himself, herself, or themselves when the context requires the neuter form. For example, “The machine switched itself off” matches the noun “machine.” Using another reflexive form without a contextual reason can create an agreement error. English provides a matching reflexive form for each personal pronoun. Once you identify the antecedent, choosing the appropriate form becomes much easier.
Adding a Space to “Itself”
In standard modern English, itself is normally written as one word. A space changes the construction from a single reflexive pronoun into the separate words its and self. Those words can appear together in specialized contexts, but they don’t create an alternative spelling of itself. For ordinary sentences, keep the pronoun intact. “The system corrected itself” is correct. “The system corrected its self” isn’t the standard way to express that meaning. This is one of those grammar points where a tiny visual change can alter the structure of the sentence.
Using “Itself” Without a Clear Antecedent
A reflexive pronoun needs a clear reference. If readers can’t tell what itself refers to, the sentence may sound awkward or confusing. For example, “After changing the settings, itself started working” doesn’t provide a suitable antecedent for the pronoun. A clearer version would name the thing first: “After changing the settings, the device started working by itself.” Good writing makes the reference easy to follow. Before keeping itself, identify the noun or pronoun it points toward. If you can’t find one, revise the sentence.
Using “Itself” When “Its” Is Required
Writers sometimes choose itself because they see the word it and assume a related form must follow. That approach causes errors. Consider “The company updated its website.” The company owns or controls the website, so its expresses possession. Writing “The company updated itself website” would be grammatically wrong because itself can’t serve as the possessive determiner before “website.” Always ask what relationship the sentence expresses. Ownership calls for its. Reflexive reference calls for itself.
When “Itself” Refers to Animals, Objects, Organizations, and Ideas
The word itself isn’t limited to physical objects. English can use it with many singular nonhuman nouns when the grammar calls for a reflexive or emphatic pronoun. Machines, devices, systems, animals, companies, organizations, situations, and abstract ideas can all take itself in suitable contexts. The important factor is the antecedent and the way the writer treats it. For example, “The software updated itself overnight” sounds natural because software commonly takes itself in this context. Likewise, “The organization itself issued the statement” uses itself for emphasis. Context helps determine whether the reference feels natural.
Using “Itself” With Objects
Objects commonly take itself when they perform an action that returns to them. “The door closed itself” means the door closed without another subject directly closing it. “The camera adjusted itself automatically” gives the same kind of reflexive meaning. These sentences work because the object functions as the grammatical subject while itself points back to that subject. In technical writing, this pattern appears frequently when systems or devices perform automated processes.
Using “Itself” With Animals
When English treats an animal as an “it,” the corresponding reflexive form is itself. For example, “The puppy scratched itself” uses a neutral reference. However, writers often choose himself or herself when they know the animal’s sex or want to emphasize the animal as an individual. The choice depends on context and the writer’s intended reference. The important point is consistency. If the antecedent takes it, the matching reflexive form is itself.
Using “Itself” With Companies and Organizations
Singular companies and organizations can also take itself when the organization functions as the antecedent. For example, “The company described itself as a market leader” uses a reflexive construction. “The company itself released the report” uses emphasis. In both cases, itself refers back to “company.” Business writing frequently uses this structure because organizations often appear as singular entities in formal US English. Always check the intended grammatical number and the style of the sentence before choosing a reflexive pronoun.
Using “Itself” With Ideas and Concepts
Abstract nouns can take itself when the grammar treats them as singular entities. For example, “The idea explains itself through the evidence” creates a reflexive relationship, although the exact meaning depends heavily on context. More commonly, writers use emphatic itself with abstract nouns: “The concept itself isn’t difficult.” Here, itself highlights the concept rather than showing an action directed back toward it. This use is especially common in analytical and academic writing.
Choosing Between “Itself,” “Himself,” and “Herself”
The correct reflexive pronoun depends on the antecedent and the reference style. A machine normally takes itself. A person usually takes himself or herself according to the intended reference. For example, “The engineer checked himself” differs from “The engineer checked herself.” When the antecedent is a nonhuman singular entity, itself generally fits. Don’t choose a reflexive form based only on the noun’s physical appearance. Follow the pronoun system and the context.
“Itself” for Reflexive Action vs. Emphasis
One reason itself can confuse learners is that the same word performs two related functions. It can show a reflexive relationship, or it can add emphasis. The surrounding sentence tells you which role it plays. Compare “The machine repaired itself” with “The machine itself repaired the fault.” In the first sentence, itself receives the action. In the second, itself emphasizes the machine as the entity responsible. Understanding this distinction makes advanced examples much easier to interpret.
Reflexive Use: The Thing Acts on Itself
Reflexive itself appears when the subject and the object refer to the same entity. “The robot moved itself across the floor” provides a clear example. The robot acts as the subject, while itself represents the object. The action therefore loops back to the subject. This relationship is the core reason English uses a reflexive pronoun instead of simply repeating the noun.
Emphatic Use: The Thing Itself
Emphatic itself works differently. It highlights a noun without acting as its direct object. Consider “The design itself isn’t complicated.” The word itself emphasizes “design.” The sentence doesn’t mean that the design acted upon itself. Instead, the writer wants readers to focus specifically on the design rather than another aspect of the subject. This construction often appears in explanations, comparisons, arguments, and formal writing.
How to Tell Which Meaning You Need
Start by looking at the verb and the sentence structure. If itself functions as the object and refers back to the subject, you’re dealing with reflexive use. If itself simply adds focus to a noun, you’re dealing with emphatic use. Try removing the word. If the sentence remains grammatical but loses emphasis, itself is probably emphatic. If removing it changes the intended reflexive relationship, the word likely serves a necessary grammatical role. This quick check can save you from guessing.
Examples That Show the Difference
Compare these examples:
- “The computer repaired itself.” — reflexive action.
- “The computer itself caused the error.” — emphasis.
- “The system restarted itself.” — reflexive action.
- “The system itself isn’t the problem.” — emphasis.
The position of itself provides a useful clue, although position alone doesn’t determine the function. In reflexive constructions, it often appears after the verb or object-related structure. In emphatic constructions, it commonly sits directly after the noun it emphasizes. Always consider the full sentence.
Common Sentence Patterns With “Itself”
Learning a few reliable patterns makes itself much easier to use. Instead of memorizing isolated examples, notice how the pronoun connects to the rest of the sentence. Most everyday constructions fall into a small number of recognizable patterns. Once you understand those patterns, you can create new sentences naturally rather than copying fixed examples.
Subject + Verb + Itself
This is one of the clearest reflexive patterns:
Subject + verb + itself
Examples include “The machine cleaned itself” and “The program updated itself.” The subject acts, and itself points back to that same subject. This pattern works particularly well with automated systems, devices, animals, and other singular entities that can logically act.
Subject + Verb + Object + Itself
Sometimes itself appears after another object-related phrase. For example, “The company presented the product itself as the main solution” would require careful context because itself may create ambiguity. A clearer emphatic structure is often “The company presented the product itself as the main solution.” Here, itself emphasizes “product.” The sentence pattern matters because reflexive and emphatic uses can look similar. Place itself close to the noun you want readers to understand.
Noun + Itself + Verb
This pattern commonly signals emphasis:
Noun + itself + verb
Examples include “The rule itself is simple” and “The device itself works well.” In both cases, itself emphasizes the noun that comes immediately before it. The word doesn’t act as the direct object. Instead, it tells readers to focus on that specific noun.
Preposition + Itself
You can also encounter itself after a preposition. For example, “The problem contains the solution within itself” uses itself to refer back to “problem.” The exact construction depends on the verb and preposition, but the same reference principle applies. Identify the noun that itself points toward, then check whether the relationship makes sense.
By Itself vs. Itself
Don’t automatically treat by itself as identical to itself. “The machine repaired itself” focuses on the action being directed back toward the machine. “The machine repaired the problem by itself” emphasizes that the machine acted independently or without outside assistance. Both expressions contain a reflexive pronoun, but the addition of by changes the meaning. This distinction becomes especially important when you want to describe automation, independence, or the absence of help.
“Itself” vs. “By Itself”: What’s the Difference?
The difference between itself and by itself may seem subtle, yet it changes what the sentence emphasizes. Itself generally identifies the entity receiving an action or highlights that entity. By itself commonly describes how an action happens. It can suggest that something acts alone, independently, or without assistance. Compare “The software updated itself” with “The software completed the installation by itself.” The first sentence focuses on the software as both actor and receiver. The second emphasizes the software’s independence during the process.
“Itself” for Reflexive Action
Use itself when the action returns to the same entity that performs it. “The device switched itself off” means the device performed the switching action and became the object of that action. The reflexive relationship remains central to the sentence.
“By Itself” for Independence
Use by itself when you want to show that something completed an action independently. “The software installed the update by itself” tells the reader that no person needed to perform the installation manually. The expression focuses on independence rather than a direct subject-object match.
“By Itself” for Being Alone
Depending on context, by itself can also mean alone or separately. For example, “The component doesn’t work well by itself” means it doesn’t function effectively without other components. Here, the phrase describes isolation rather than reflexive action. Context determines the precise meaning.
Examples of Both Constructions
- The robot cleaned itself.
- The robot completed the task by itself.
- The phone restarted itself.
- The phone installed the update by itself.
The first example in each pair describes reflexive action. The second highlights independent action. Keeping that distinction in mind will help you choose the right expression without overthinking the grammar.
Examples of “Itself” in Sentences
Examples become more useful when they show different grammatical functions rather than repeating one pattern. The following examples cover everyday, formal, academic, business, and technical contexts. Each one demonstrates how itself behaves naturally in real writing.
Everyday English Examples
- The door opened itself.
- The dog hurt itself while playing.
- The phone turned itself off.
- The toy moved itself across the floor.
- The problem will resolve itself eventually.
These sentences use itself in familiar situations. In each example, the pronoun refers back to a singular antecedent. The surrounding context makes that reference clear.
Formal English Examples
Formal writing often uses itself to create precise emphasis. For example, “The policy itself isn’t controversial” highlights the policy rather than the surrounding debate. Similarly, “The procedure can correct itself under certain conditions” uses a reflexive construction. Formal style doesn’t change the basic grammar. It simply places the word in more structured sentences.
Academic Writing Examples
Academic writers often use emphatic itself when distinguishing an idea from its consequences. For example, “The theory itself doesn’t explain the observed result.” Here, itself narrows the focus to the theory. Another example is “The phenomenon cannot explain itself without additional evidence.” In that sentence, itself participates in a reflexive construction. The meaning depends on the relationship between the noun and the verb.
Business Writing Examples
Business communication frequently uses itself when discussing companies, products, systems, and processes. For example, “The company itself confirmed the change” emphasizes who confirmed it. “The platform can update itself automatically” describes an automated process. These constructions help writers make responsibility and function clear without adding unnecessary explanation.
Technical Writing Examples
Technical documentation often describes automated systems with reflexive verbs. You might read sentences such as “The application restarts itself after an unexpected shutdown” or “The device calibrates itself during setup.” These examples show why the single-word form matters. The system acts, and the action refers back to that same system. In technical contexts, precise pronoun use can prevent ambiguity and make instructions easier to understand.
Examples With Reflexive Use
Reflexive itself appears when the subject and object share the same reference:
- The system repaired itself.
- The machine cleaned itself.
- The animal protected itself.
- The program restarted itself.
Each sentence creates a clear action loop. The subject starts the action, then itself points back to that subject.
Examples With Emphatic Use
Emphatic itself highlights a noun:
- The machine itself isn’t dangerous.
- The rule itself is easy to understand.
- The product itself performed well.
- The organization itself released the statement.
Removing itself would leave each sentence grammatical, but the emphasis would disappear. That’s the easiest clue that the word serves an emphatic role.
Examples of Incorrect and Correct Usage
Incorrect: The computer repaired its self.
Correct: The computer repaired itself.
Incorrect: The company updated itself website.
Correct: The company updated its website.
Incorrect: Its working normally now.
Correct: It’s working normally now.
Incorrect: The device fixed it self.
Correct: The device fixed itself.
These corrections show why spelling alone isn’t enough. You need to identify the grammatical function first, then choose the appropriate form.
Why Do People Confuse “Itself” and “Its Self”?
The confusion between itself and its self usually starts with how the words sound. When spoken quickly, the boundary between the sounds can seem unclear. That can make a writer wonder whether itself should contain a space. English spelling doesn’t always match the way words sound, so pronunciation alone can’t settle the question. The grammar provides a much better guide. When itself works as a reflexive pronoun, it forms one word. When it modifies the noun self, the words remain separate. The second construction has a different meaning and appears far less often. Once you connect spelling with grammatical function, this particular confusion becomes much easier to avoid.
Similar Sound and Pronunciation
Spoken English can blur word boundaries, especially when people speak quickly. It contains the sounds of “it” and “self,” so learners may naturally imagine two separate words. Writing follows established spelling conventions rather than every sound we hear. The same principle applies to other compounds and pronouns in English. If the word functions as the reflexive form of it, write itself as one word. Listening carefully can help with pronunciation, but checking the grammatical role gives you the stronger answer.
Spell-Check and Grammar-Check Limitations
Digital writing tools can catch many spelling errors, but they don’t understand every grammatical choice perfectly. A spell-checker may recognize itself as a valid word without explaining why it belongs in a particular sentence. It may also accept its and it’s because both forms are legitimate English words. The real challenge comes from choosing the form that matches the intended meaning. That’s why human editing still matters. Read the complete sentence and identify the relationship between the subject, verb, object, and surrounding nouns. A tool can flag unusual wording, but context often determines the correct form.
Influence of Spoken English
Everyday speech often reduces sounds and blends nearby words. As a result, learners may rely on pronunciation when deciding how to spell it. That approach can cause trouble because spoken English doesn’t always reveal grammatical boundaries clearly. Writing requires the standard written form. In normal US English, the reflexive pronoun remains itself, whether someone speaks quickly or slowly. The written form doesn’t change simply because the pronunciation sounds like separate pieces.
Misunderstanding Possessive Pronouns
Another source of confusion involves the relationship between its and itself. Writers sometimes see its inside itself and assume the two forms share the same grammatical function. They don’t. Its expresses possession or association, while itself usually refers back to an antecedent in a reflexive or emphatic role. Compare “The device lost its battery” with “The device repaired itself.” The first sentence describes something connected to the device. The second sends the action back to the device. Recognizing that difference removes much of the uncertainty.
How to Remember When to Use “Itself”
A few quick tests can make this grammar point almost automatic. Instead of memorizing complicated terminology, look at what the sentence is trying to say. If something acts on the same thing represented by it, think itself. If you need to show possession, think its. If you can replace the form with “it is” or “it has,” think it’s. These simple checks work because they focus on meaning and grammatical function. They also make proofreading faster. You don’t need to stop and analyze every grammatical label when a short test can reveal the answer.
The Reflexive Pronoun Test
First, ask whether the subject performs an action that comes back to the same entity. If it does, a reflexive pronoun may be necessary. For example, “The machine cleaned itself” passes the test because the machine performs the cleaning and receives the action. If the action involves two different entities, don’t automatically use itself. “The technician cleaned the machine” doesn’t need a reflexive pronoun because the technician and machine are different.
The Subject-and-Object Test
Identify the subject and object of the sentence. Then ask whether they refer to the same thing. In “The robot moved itself,” the robot acts as the subject while itself represents the object. Both refer to the robot. That shared reference explains the reflexive form. If the subject and object refer to different entities, use an ordinary object pronoun or noun instead.
The “It Acts on Itself” Test
Try saying the sentence in plain language: “Does it act on itself?” If the answer is yes, itself will often be the correct choice. Consider “The program updated itself.” The program performs the update, and the update affects the program. The action creates a loop back to the subject. This test won’t cover every emphatic use, but it works especially well for reflexive constructions.
The Possession Test for “Its”
Ask whether you mean “belonging to it” or “associated with it.” If you do, use its. For example, “The company changed its name” expresses possession or association. The company doesn’t change itself in this sentence. Instead, the company changes something connected to it. This quick meaning check helps separate its from itself.
The Contraction Test for “It’s”
Replace it’s with “it is” or “it has.” If the sentence still makes sense, the contraction may be correct. “It’s ready” becomes “It is ready.” “It’s already started” becomes “It has already started.” If neither expansion works, you probably need its or itself instead. This test is particularly useful during proofreading because apostrophe errors are easy to overlook.
The One-Word Test for “Itself”
When you need the reflexive pronoun connected with it, remember one simple rule: itself is one word. Don’t insert a space just because the word contains it and self. Think of itself as a complete grammatical unit, just like myself or herself. The separate phrase its self has a different structure and a much narrower use.
Practice: Is It “Itself” or “Its Self”?
Practice works best when you focus on the reason behind each answer. Don’t simply choose a word and move on. Identify the subject, check the meaning, then decide which form fits the sentence. This method builds a useful editing habit rather than encouraging guesswork.
Choose the Correct Form
Choose itself, its, or it’s in each sentence:
- The computer restarted ______ after the update.
- The company changed ______ privacy policy.
- ______ difficult to explain the issue in one sentence.
- The device can monitor ______ while operating.
- The organization defended ______ against the criticism.
- The software changed ______ settings automatically.
- The machine ______ isn’t the problem.
- The animal injured ______ while escaping.
Answers and Grammar Explanations
- itself — The computer acts and refers back to itself.
- its — The policy belongs to or relates to the company.
- it’s — The sentence means “It is difficult.”
- itself — The device monitors the same entity represented by the reflexive pronoun.
- itself — The organization performs an action directed back toward itself.
- its — The settings belong to or are associated with the software.
- itself — The word emphasizes the machine.
- itself — The animal acts and receives its effect.
Correct the Mistakes
Now look at these common errors:
- The phone turned itself off.
- The company updated its website.
- It’s working again.
- The system repaired itself.
- The machine changed its settings by itself.
The corrected versions are:
- The phone turned itself off.
- The company updated its website.
- It’s working again.
- The system repaired itself.
- The machine changed its settings by itself.
The final sentence is already correct. Here, its shows possession, while by itself indicates independent action. Seeing the two forms together provides a useful reminder that they don’t perform the same grammatical job.
Real-World Usage of “Itself”
The distinction between itself and its self matters most when writing needs to sound clear and precise. Different fields use these forms in slightly different contexts, but the underlying grammar remains stable. Academic writers may use itself to emphasize an idea. Businesses may use it when discussing an organization or automated process. Technical writers often use it to describe systems that perform actions automatically. Literature can use itself more abstractly when discussing identity or character. Understanding these contexts helps you recognize why the same word can appear in very different sentences.
Itself in Academic Writing
Academic writing often uses emphatic itself to separate an idea from its effects or interpretations. For example, “The theory itself doesn’t account for the difference” focuses specifically on the theory. Writers may also use reflexive itself when describing processes or systems. The grammatical principle doesn’t change because the writing becomes more formal. The subject, object, and intended reference still determine the correct form.
Itself in Business Communication
Business communication frequently discusses companies, organizations, products, and services as singular entities. That makes it useful in sentences such as “The company itself confirmed the announcement.” It can also describe automated business systems: “The platform updates itself overnight.” Clear pronoun use matters here because a small grammatical error can make a sentence sound careless or ambiguous. Choosing itself correctly keeps professional writing polished.
Itself in Technical Documentation
Technical documentation often describes software, devices, networks, and automated processes. These subjects commonly perform actions without direct human intervention. As a result, reflexive itself appears naturally in sentences such as “The application restarts itself after a failure.” Another example is “The sensor calibrates itself during startup.” These constructions tell readers exactly what the system does. Precision matters in technical writing, so the distinction between itself, its, and it’s deserves careful attention.
Itself in Everyday Communication
Everyday writing uses itself in straightforward situations. You might write, “The door locked itself” or “The dog cleaned itself.” You can also use it for emphasis: “The product itself isn’t expensive.” These examples show that the rule isn’t limited to formal grammar exercises. Once you understand the underlying relationship, you can apply it naturally in texts, emails, posts, schoolwork, and ordinary conversation.
Itself in Literature
Literary writing gives self a broader role because authors often explore identity, consciousness, character, and inner nature. A writer might use self as a noun when discussing a character’s identity. Itself can still function normally as a reflexive or emphatic pronoun. The creative setting doesn’t erase standard grammar. However, literary authors may deliberately use unusual constructions for style or philosophical effect. That’s one reason readers can occasionally encounter its self outside ordinary usage.
Historical Background of “Itself”
The form itself reflects a broader pattern in the development of English reflexive pronouns. English has long combined personal pronouns with forms related to self to create reflexive constructions. Modern forms such as myself, yourself, himself, herself, and itself now function as established pronouns. Over time, these combinations became fixed written forms rather than ordinary phrases containing a possessive determiner and a noun. That history helps explain why modern English treats itself as one word. The form isn’t simply a casual shortening of “its self.” It has developed into a distinct grammatical unit.
How “Itself” Developed in English
The development of reflexive forms involved combinations of pronouns with self. English gradually established these combinations as regular reflexive constructions. Modern readers therefore recognize itself as a standard pronoun rather than interpreting it as two separate words. Similar development appears in other reflexive forms. The important point for modern writers is that the established form has a specific grammatical function.
The Relationship Between “It” and “Self”
The relationship becomes clearer when you compare it with itself. It functions as a personal pronoun in suitable contexts. Itself adds the reflexive or emphatic element. The two forms therefore belong to the same grammatical family. The presence of self doesn’t mean that the word should be separated. In the established reflexive form, itself works as one unit.
Why Modern English Uses “Itself” as One Word
Modern standard English has settled on itself as the normal spelling for the reflexive pronoun. Writers don’t generally create the form by joining its and self each time they need it. Instead, itself already exists as the correct lexical item. That’s why “The machine fixed itself” follows standard usage while “The machine fixed its self” normally does not.
How to Edit Your Writing for “Itself”
A quick editing routine can catch most mistakes involving itself, its, and it’s. Start with the sentence’s meaning. Then identify the antecedent and grammatical role. Don’t rely on how the word sounds. Finally, read the sentence once more to make sure the reference remains clear. This process takes only a few seconds once you’ve practiced it.
Identify the Antecedent
Find the noun or pronoun that it refers to. In “The device repaired itself,” the antecedent is “device.” If you can’t identify a clear antecedent, reconsider the sentence. A reflexive pronoun shouldn’t leave readers wondering what it represents.
Check Whether the Action Is Reflexive
Ask whether the subject and object refer to the same entity. If they do, itself may be necessary. For example, “The system restarted itself” creates a clear reflexive relationship. If another entity acts, you may need a regular noun or object pronoun instead.
Check Whether “Itself” Adds Emphasis
Remove itself temporarily. If the sentence remains grammatical but loses a specific emphasis, the word may serve an emphatic role. “The rule itself is simple” becomes “The rule is simple.” The second sentence still works, but it doesn’t emphasize the rule in the same way.
Check for Possession
If the word introduces something that belongs to or relates to the antecedent, check whether it fits. “The device lost its power” expresses possession or association. You wouldn’t use itself before “power” in that structure.
Test Whether “It’s” Means “It Is” or “It Has”
Replace it’s with “it is” or “it has.” If the expansion works, keep the contraction. If it doesn’t, reconsider the form. This simple substitution test catches many errors quickly.
Look for Unnecessary Spaces
Search your draft for “it self” or “its self.” If you intend the standard reflexive pronoun, change it to itself. Keep itself only when the sentence genuinely treats self as a separate noun modified by its. That situation is unusual, so check the surrounding context carefully.
Quick Reference Chart
| Word or Phrase | Function | When to Use It | Example |
| itself | Reflexive pronoun | When an action refers back to a singular nonhuman antecedent | The machine repaired itself. |
| itself | Emphatic pronoun | When you want to emphasize a noun | The machine itself caused the problem. |
| its | Possessive determiner | To show possession or association | The machine lost its power. |
| it’s | Contraction | As a shortened form of “it is” or “it has” | It’s working now. |
| its self | Possessive determiner + noun | In rare contexts where self functions independently as a noun | The writer discussed the entity in relation to itself. |
The practical rule is straightforward: use itself when you need the standard reflexive or emphatic pronoun. Use its for possession. Use it’s when you mean “it is” or “it has.” Reserve itself for unusual contexts where self genuinely functions as a separate noun.
Conclusion
Choosing between self, itself, its, and it’s becomes much easier once you focus on what each word does in a sentence. Itself is normally the correct choice when a singular nonhuman subject performs an action on itself or when you want to add emphasis. Self usually works as a noun when you’re discussing identity, nature, or the idea of an individual self. Meanwhile, its shows possession, and it’s means “it is” or “it has.” The key is to look at the sentence structure rather than rely on how the words sound. With a little practice, you can quickly identify the subject, understand the intended meaning, and choose the right form. Whether you’re writing an email, school assignment, business document, or everyday message, this simple approach will help you use these easily confused words with greater confidence and clarity.
FAQs
Is “itself” one word?
Yes, itself is normally written as one word in standard English. It functions as a reflexive or emphatic pronoun. For example, “The machine repaired itself” uses itself because the machine performs an action that refers back to the machine. Writing “it self” is generally incorrect when you mean the standard reflexive pronoun.
What is the difference between “self” and “itself”?
Self is usually a noun referring to a person’s or thing’s identity, nature, or individual being. Itself is a pronoun that refers back to a singular nonhuman subject or adds emphasis. For example, “The self is complex” uses self as a noun, while “The machine repaired itself” uses itself as a reflexive pronoun.
Is “its self” grammatically correct?
Its self can be grammatically possible when its modifies self as a separate noun, but this construction is uncommon in ordinary English. In most sentences where writers mean the reflexive pronoun, itself is the correct form. For example, “The device fixed itself” is standard, while “The device fixed its self” is not.
When should I use “itself”?
Use itself when a singular nonhuman subject performs an action that refers back to the same entity. For example, “The computer restarted itself” means the computer restarted without another subject performing that action on it. You can also use itself for emphasis, as in “The computer itself isn’t the problem.”
What does “itself” mean in a sentence?
Itself generally refers back to a singular nonhuman noun or pronoun. It can show that the subject and object are the same thing, as in “The door closed itself.” It can also emphasize a noun, as in “The rule itself is simple.” The surrounding sentence determines which function itself performs.
What is the difference between “its” and “itself”?
Its normally expresses possession or association, while itself works as a reflexive or emphatic pronoun. Compare “The company changed its policy” with “The company defended itself.” In the first sentence, its connects the company with its policy. In the second, itself refers back to the company as the receiver of the action.
What is the difference between “it’s” and “itself”?
It’s is a contraction meaning “it is” or “it has.” Itself is a reflexive or emphatic pronoun. For example, “It’s ready” means “It is ready,” while “The device repaired itself” shows that the device performed an action affecting itself. These words have different grammatical functions and cannot normally replace each other.
Can “itself” be used for animals?
Yes. When English refers to an animal with the pronoun it, the matching reflexive form is itself. For example, “The puppy hurt itself while playing.” However, if the animal is treated as a specific individual and referred to as he or she, the corresponding reflexive pronoun would be himself or herself.
Can “itself” be used for a company?
Yes. A singular company or organization can take itself when the pronoun refers back to that entity. For example, “The company described itself as innovative.” You can also use itself for emphasis: “The company itself released the statement.” The correct choice depends on whether the word is reflexive or emphatic.
How can I remember whether to use “itself,” “its,” or “it’s”?
Use itself when the action refers back to the subject or when you want emphasis. Use its to show possession or association. Use it’s when you mean “it is” or “it has.” A quick substitution test helps: if “it is” or “it has” works, choose it’s. Otherwise, check whether you need possession or reflexive reference.
