Eachother or Each Other is a common English grammar question, but only each other is the correct spelling, written with a space between the two words.
When Native speakers and language learners study the English language, they may confuse these English terms because eachother looks familiar. However, each other is the correct form, while eachother is an incorrect spelling with no space. In grammar, each other works as a reciprocal pronoun and shows that people do something mutually. For examples, My brother and I always buy each other souvenirs when we travel, and there’s a lot to learn from this simple sentence. People can love each other very much, yet still make this mistake in writing. In my experience, an online search can create confusion, while reliable English dictionaries help readers understand the difference.
Several trusted references recognize each other as the standard form and do not accept eachother as a proper pronoun. These include the Longman Dictionary of Contemporary English, American Heritage English Dictionary, and Collins Cobuild Advanced Learner’s English Dictionary, including their new versions. This follows the same school of thought used in standard English and helps people write better and communicate better.

Eachother vs. Each Other: The Short Answer
If you’re in a hurry, here’s the answer:
| Form | Correct? | Meaning |
| Each other | Yes | Refers to mutual actions between people or things |
| Eachother | No | Incorrect spelling |
The correct form is always each other as two separate words.
Examples
They trust each other.
We support each other during difficult times.
The players congratulated each other after the match.
They trust eachother.
We support eachother.
No major English dictionary recognizes eachother as a standard word.
What Does “Each Other” Mean?
The phrase each other is a reciprocal pronoun.
A reciprocal pronoun shows that two or more people perform the same action toward one another.
In simple terms, it describes a relationship where the action goes both ways.
Simple Definition
Each other means that one person does something to another person and receives the same action in return.
Think of it as a verbal boomerang. The action travels from one person to another and then comes back.
Examples
- Sarah and Emma text each other daily.
- The neighbors help each other during emergencies.
- The children shared their toys with each other.
- The business partners trust each other completely.
In every example, the action is mutual.
Why “Eachother” Is Incorrect
Many people assume eachother should be one word.
That assumption makes sense. English contains thousands of compound words formed by combining smaller words.
Examples include:
- Everyone
- Somebody
- Anyone
- Everything
- Whatever
Because these words exist, writers naturally expect eachother to follow the same pattern.
Yet English grammar treats each other differently.
The phrase remains two separate words because it functions as a reciprocal pronoun rather than a standard compound word.
Why People Make This Mistake
Several factors contribute to the confusion:
- Fast typing habits
- Mobile keyboards
- Lack of grammar instruction
- Similar-looking compound words
- Informal online writing
Many writers simply never notice the error until a grammar checker highlights it.
Is “Each Other” One Word or Two Words?
The answer is straightforward:
Each other is always written as two words.
This rule applies in:
- Academic writing
- Business communication
- Journalism
- Creative writing
- Emails
- Textbooks
- Professional documents
There are no standard exceptions.
Breaking Down the Phrase
The phrase consists of two separate words that work together.
| Word | Meaning |
| Each | Every individual member |
| Other | Another person or thing |
Together, they express mutual action between members of a group.
Example
“The friends encouraged each other.”
This means:
- Friend A encouraged Friend B.
- Friend B encouraged Friend A.
The encouragement flowed both directions.
The Grammar Behind “Each Other”
To understand why the phrase remains separate, it helps to know how reciprocal pronouns work.
What Is a Reciprocal Pronoun?
A reciprocal pronoun expresses a two-way relationship.
Instead of focusing on one person’s action, it highlights a shared exchange.
English contains only two reciprocal pronouns:
- Each other
- One another
That’s it.
Unlike personal pronouns such as he, she, they, or we, reciprocal pronouns specifically describe mutual actions.
Examples
- They respect each other.
- We admire each other.
- The team members encouraged one another.
The action occurs between all participants.
Each Other vs. One Another
This is another area that confuses many writers.
Both phrases serve the same purpose.
Traditional Rule
Older grammar books often teach this distinction:
| Expression | Traditional Usage |
| Each other | Two people or things |
| One another | Three or more people or things |
Examples:
- Jack and Mia trust each other.
- The committee members respect one another.
Modern Usage
Modern English has largely abandoned this strict distinction.
Today, most grammar authorities treat the two expressions as interchangeable.
You’ll find both used in:
- Newspapers
- Books
- Academic journals
- Business writing
Examples
Correct:
- The sisters support each other.
- The sisters support one another.
Correct:
- The employees respect each other.
- The employees respect one another.
Both versions sound natural.

Possessive Forms of “Each Other”
Many writers understand the basic phrase but struggle with possessive usage.
Correct Possessive Form
The possessive version is:
each other’s
Examples
- The players respected each other’s abilities.
- The friends borrowed each other’s books.
- The partners admired each other’s strengths.
- The siblings wore each other’s clothes.
Why the Apostrophe Matters
The apostrophe shows ownership.
Without it, the sentence becomes grammatically incorrect.
Common Possessive Errors
| Incorrect | Correct |
| each others | each other’s |
| eachother’s | each other’s |
| eachothers | each other’s |
Only each other’s follows standard English grammar.
Common Grammar Mistakes Related to Each Other
Even experienced writers occasionally make these errors.
Writing It as One Word
Incorrect:
- We support eachother.
Correct:
- We support each other.
Using the Wrong Possessive
Incorrect:
- They admired each others work.
Correct:
- They admired each other’s work.
Confusing Reciprocal and Reflexive Pronouns
These pronouns serve different purposes.
Reciprocal Pronoun
- They helped each other.
Reflexive Pronoun
- They helped themselves.
The first sentence describes mutual assistance.
The second describes self-directed action.
Redundant Wording
Avoid unnecessary repetition.
Weak:
- They mutually helped each other.
Better:
- They helped each other.
The phrase already implies mutual action.
How to Remember the Correct Spelling
Fortunately, remembering the rule is easy.
The Two-People Rule
Visualize two individuals standing apart.
The space between them reminds you that each other requires two separate words.
The Dictionary Test

“Would I find ‘eachother’ in a dictionary?”
