Eachother or each other is a small English question, but it causes a surprisingly large number of mistakes. Many learners know what the expression means, yet they are not sure whether it should be written as one word or two words Eachother or Each Other.
The correct form in standard English is each other — always written as two separate words.Eachother or Each Other.
You may see eachother online, in quick messages, comments, or informal writing. However, eachother is not the standard spelling and should not be used in careful English. This simple difference matters when you are writing school assignments, emails, blog posts, exams, professional messages, or other formal text.Eachother or Each Other.
The good news is that the rule is easy once you understand how the expression works. Each other is a reciprocal pronoun. We use it when two or more people or things do something to, for, or with one another.Eachother or Each Other.
For example:
- Sarah and Tom helped each other.
- The two friends called each other every evening.
- We should respect each other.
The main question is not really about meaning. It is mainly about correct spelling and grammar.
By the end of this guide, you will know the difference between eachother or each other, understand the grammar behind each other, learn common mistakes, and see how native speakers use it in everyday English.
What Does “Eachother” Mean?
First, let us look at eachother.
The important point is simple: eachother is not the standard English form. It is usually a spelling mistake caused by joining the two words together.
You might find eachother in internet comments, social media posts, text messages, or other casual writing. Seeing it online does not make it grammatically correct.Eachother or Each Other.
For standard English, write:
each other
not:
eachother
This is similar to other English expressions that contain two separate words. The fact that two words work closely together does not always mean they should be joined.Eachother or Each Other.
Is “Eachother” Ever Correct?
In modern standard English, eachother is generally considered incorrect when you mean the reciprocal expression.
For example:
❌ The students helped eachother.
The standard version is:
✅ The students helped each other.
Another example:
❌ They always support eachother.
Correct:
✅ They always support each other.
If you are writing for school, university, work, a website, or an English-learning audience, use each other.Eachother or Each Other.
Why Do People Write “Eachother”?
The mistake is understandable. When people speak quickly, each other sounds like one smooth phrase. Learners may therefore think it is a single word.Eachother or Each Other.
English has many expressions that sound connected when spoken. But pronunciation does not always tell us how words should be written.Eachother or Each Other.
For example:
- a lot is two words, not alot.
- at least is two words.
- each other is two words.
So, when you are unsure about eachother or each other, remember that the standard form contains a space.
Examples With the Incorrect Form
These examples show common mistakes:
❌ My brother and I understand eachother.
✅ My brother and I understand each other.
❌ The children were talking to eachother.
✅ The children were talking to each other.
❌ We need to listen to eachother.
✅ We need to listen to each other.
❌ The players encouraged eachother.
✅ The players encouraged each other.
❌ They looked at eachother and laughed.
✅ They looked at each other and laughed.
The pattern is easy: whenever you want this reciprocal expression, use each other as two words.
What Does “Each Other” Mean?
Each other is the correct standard form.
It is used when people or things in a group have a mutual or reciprocal relationship. In simple words, one person does something to another person, and the relationship goes in both directions.Eachother or Each Other.
Consider this sentence:
Ali helped Ahmed, and Ahmed helped Ali.Eachother or Each Other.
We can make it shorter:
Ali and Ahmed helped each other.
The expression removes the need to repeat the names.
When Do We Use “Each Other”?
We commonly use each other when two or more people perform an action mutually.
For example:
- The two sisters love each other.
- My friends always help each other.
- We should respect each other.
- The children were talking to each other.
- The players encouraged each other.
- They looked at each other and smiled.
- The neighbors often visit each other.
- The students shared their notes with each other.
Notice that each other does not mean simply “another person.” It usually expresses a relationship in which the action connects members of the same group.Eachother or Each Other.
The Basic Grammar Pattern
A common structure is:
Subject + verb + each other
Examples:
The girls helped each other.
The boys teased each other.
We understand each other.
It can also come after a preposition:
verb + preposition + each other
Examples:
They talked to each other.
We listened to each other.
The children played with each other.Eachother or Each Other.
They were angry with each other.
This is one reason learners need to understand the expression as a grammatical unit rather than simply memorizing its spelling.
Possessive Form
When something belongs to the people in the relationship, we can use:
each other’s
For example:
They read each other’s messages.
This means that one person reads another person’s messages and the relationship works in both directions.Eachother or Each Other.
Another example:
The students checked each other’s answers.
Here, the students checked the answers belonging to one another.
Notice the apostrophe:
each other’s
not:
❌ eachothers
and not:
❌ each others
More Examples
Here are some natural examples:
My parents always support each other.
The two teams congratulated each other after the match.Eachother or Each Other.
We should be kind to each other.
The brothers often argue with each other.
The children were laughing at each other.
The workers depend on each other.
The two friends trust each other.
Good classmates help each other when someone has a problem.
The correct expression in every example is each other.Eachother or Each Other.
Difference Between “Eachother” and “Each Other”
The difference between eachother or each other is straightforward.
Each other is correct.
Eachother is not the standard spelling.
There is no important difference in meaning because eachother is normally just an incorrect attempt to write each other as one word.
| Form | Correct? | Meaning | Example |
|---|---|---|---|
| each other | ✅ Yes | One another; mutually | They help each other. |
| eachother | ❌ No | Intended to mean each other | They help eachother. |
| each other’s | ✅ Yes | Belonging mutually to the people involved | They read each other’s books. |
| eachothers | ❌ No | Incorrect form | Avoid this spelling. |
So, if you are deciding between eachother or each other, choose each other.Eachother or Each Other.
Usage Difference
There is no standard usage situation in which you should choose eachother instead of each other.
For example:
❌ The girls trust eachother.
✅ The girls trust each other.
The second sentence is the one you should use.
Grammar Logic
The expression each other consists of two words:
- each
- other
Together, they form a reciprocal pronoun.
The word each points to the individual members of a group. The word other connects those individuals with one another.
For example:
John and Mary help each other.
John helps Mary, and Mary helps John.
The phrase therefore expresses a mutual action.
Sentence Structure
You can use each other in several positions.
After a verb:
They respect each other.
After a preposition:
They talked to each other.
With possession:
They borrowed each other’s books.
The important spelling rule stays the same. Write the main expression as two words.
Meaning Comparison
When someone asks about eachother or each other, they are usually asking whether the two-word expression can be combined.
It cannot be combined in standard English.
Think of it this way:
Correct: each + space + other
Incorrect: eachother
That small space is important.
Grammar Rules You Must Remember
1. Always Write “Each Other” as Two Words
This is the most important rule.
Write:
They love each other.
Do not write:
They love eachother.
When checking your writing, look specifically for the joined form.
2. Use It for Mutual Actions
Each other normally shows that an action is shared between people or members of a group.
The two friends helped each other.
The meaning is that Friend A helped Friend B, and Friend B helped Friend A.
3. It Can Follow a Preposition
Do not remove the space when a preposition comes before the phrase.
Correct:
They spoke to each other.
We listened to each other.
The children played with each other.
The phrase remains each other.
4. Use “Each Other’s” for Possession
When you want to show that something belongs to another member of the group, use each other’s.
The students checked each other’s work.
The sisters borrowed each other’s clothes.
The apostrophe and s are important.
5. Do Not Confuse It With “Another”
Each other and another are related in meaning, but they are not always interchangeable.
Compare:
The two friends help each other.
This means they both help one another.
But:
I need another pen.
Here, another means one more or an additional one.
Understanding this difference can prevent another common grammar mistake.
Common Mistakes Students Make
Mistake 1: Joining the Words
This is the biggest problem with eachother or each other.
❌ We should respect eachother.
✅ We should respect each other.
Correction tip: Say the phrase slowly while writing it: “each — other.” Remember the space.
Mistake 2: Writing “Each Others”
Some learners write:
❌ They read each others books.
The correct form is:
✅ They read each other’s books.
The apostrophe shows possession.
Mistake 3: Forgetting the Preposition
Some sentences need a preposition.
❌ They talked each other.
✅ They talked to each other.
The correct preposition depends on the verb.
Other examples include:
They listened to each other.
They looked at each other.
They argued with each other.
Mistake 4: Using “Each Other” When the Meaning Is Not Mutual
Consider:
I bought another shirt.
Here, another is correct because the speaker means one additional shirt.
You would not normally say:
I bought each other shirt.
That has a completely different structure.
Mistake 5: Thinking Internet Usage Makes “Eachother” Correct
You may see eachother on social media or in comments.
That does not make it standard English.
Online writing often contains spelling shortcuts, missing punctuation, and grammar mistakes. When learning English, follow standard forms used in dictionaries, edited writing, education, and professional communication.
Easy Trick to Remember the Difference
Think: “Each” + “Other” = Two People or More
The easiest memory trick for eachother or each other is to imagine two people standing apart.
Each = individual members.
Other = the other person.
So keep the two words separate:
each + other = each other
Imagine a teacher writing this on the board:
Sara ↔ Ahmed
The arrow points both ways. Sara helps Ahmed, and Ahmed helps Sara.
That is the basic idea of each other.
A Simple Spelling Test
Ask yourself:
Would I write “each” and “other” as two separate words when speaking about mutual action?
The answer is yes.
So:
✅ each other
❌ eachother
A second trick is to remember the possessive form:
each other’s
If you can remember the apostrophe in each other’s, it becomes easier to remember that each other starts as two separate words.

For example:
They borrowed each other’s books.

Conclusion
The answer to eachother or each other is simple: each other is the correct standard form.
Always write it as two words when you are talking about people or things doing something mutually. For example, We help each other, They respect each other, and The children played with each other are all correct.
The one-word form eachother may appear in online writing, but it should not be used in careful English. If you are writing an assignment, email, article, application, or professional message, choose the standard spelling.
Also remember the possessive form each other’s, as in They checked each other’s work.
The easiest memory trick is to keep each and other separate. Think of two people connected by a two-way relationship: one person does something to the other, and the action can go back in the other direction.
So, whenever you wonder about eachother or each other, stop for a second and remember:
each + other = each other.
A tiny space makes the difference, and with a little practice, you will stop making this common spelling mistake.
