Eachother or Each Other: Which Spelling Is Correct?

Have you ever typed eachother and then stopped to wonder if it should be written as one word or two? This is a small spelling question, but it can cause problems in school work, emails, social media posts, and professional writing.

The correct form is each other, written as two separate words.

Eachother is not the standard spelling in modern English. It is usually a spelling mistake that happens because the two words sound closely connected when we speak.

For example:

We should help each other.

Not:

We should help eachother.

The phrase each other is used when people or things have a mutual action or relationship. It can describe two people, several people, or things that affect one another.

The good news is that the rule is simple. You do not need to remember a difficult grammar rule. Just remember that each other always has a space in standard English.

Eachother or Each Other – Quick Answer

Each other is correct.

Eachother is not the standard spelling.

Use each other when you mean that people or things act toward one another.

Correct examples

• We help each other.
• They love each other.
• The two friends trust each other.
• The teams respect each other.
• We should listen to each other.

Incorrect spelling

• We help eachother. ❌
• They love eachother. ❌
• The friends trust eachother. ❌

The main rule is very easy:

Each other = two words ✅

Eachother = one word ❌

Cambridge Dictionary also states that each other is written as two separate words and not as one word or with a hyphen.

The Origin of Each Other

The phrase each other has a long history in English.

It comes from older forms of English. Etymology sources trace the expression back through Middle English to Old English. Older forms included phrases such as ech other, yche othere, and similar forms.

The two parts are simple:

• each means every person or thing considered separately
• other means another person or thing

Together, each other expresses a mutual relationship.

For example:

Tom and Sam help each other.

This means Tom helps Sam, and Sam helps Tom.

The phrase did not become a single standard word like someone, everyone, or anybody. Modern English still keeps each and other as separate words.

This may explain why the spelling can feel strange to some writers. English has many words that started as separate words and later joined together. But each other has remained a two-word expression in standard modern English.

British English vs American English Spelling

There is no spelling difference between British English and American English for this phrase.

Both use:

each other

Not:

eachother

For example:

English variety	Correct form	Incorrect form
American English	each other	eachother
British English	each other	eachother
Canadian English	each other	eachother
Australian English	each other	eachother
International English	each other	eachother

So you do not need to change the spelling based on your country.

American English example

The two students helped each other.

British English example

The two students helped each other.

The spelling stays the same.

There is also no need for a hyphen:

❌ each-other

❌ eachother

✅ each other

Cambridge specifically notes that each other is written as two separate words and does not use a hyphen.

Which Spelling Should You Use?

Use each other in every type of normal English writing.

This includes:

• School assignments
• University work
• Emails
• Business writing
• Websites
• News writing
• Social media
• Text messages
• Formal documents
• Everyday writing

You do not need a different spelling for the US, UK, Canada, Australia, or other English-speaking regions.

If you are writing a university paper, use:

Students should support each other.

If you are writing an email, use:

Please keep each other updated.

If you are writing a social media post, use:

We should always support each other.

The same spelling works in all three situations.

Common Mistakes with Eachother or Each Other

1. Writing eachother as one word

This is the most common mistake.

❌ We should respect eachother.

✅ We should respect each other.

Always leave a space between each and other.

2. Adding a hyphen

Some people write:

❌ each-other

This is also not the standard form.

Use:

✅ each other

3. Writing “each others”

Another common mistake happens with the possessive form.

❌ They respect each others opinions.

✅ They respect each other’s opinions.

The possessive form is:

each other’s

The apostrophe comes before the s.

4. Writing “each others’”

This is usually wrong when you mean mutual possession.

❌ They borrowed each others’ books.

Better:

✅ They borrowed each other’s books.

For example:

The students read each other’s work.

This means one student’s work was read by another student.

5. Confusing each other with one another

Each other and one another often have the same meaning.

For example:

They helped each other.

and

They helped one another.

Both are natural.

Some traditional grammar guides tried to use each other for two people and one another for more than two. Modern usage does not always follow this rule. Cambridge says there is very little difference between the two expressions and that each other is more common.

Each Other in Everyday Examples

The phrase appears in many types of writing.

In emails

Please keep each other informed about the project.

We need to support each other during the busy period.

In school writing

Good students often help each other with difficult work.

The two groups learned from each other.

In business writing

The two companies work closely with each other.

Team members should communicate with each other.

In news writing

The two sides blamed each other for the problem.

The countries agreed to work with each other.

On social media

We should always support each other.

They have known each other for years.

In everyday speech

Do you two know each other?

We see each other every week.

They are always helping each other.

These examples show why the phrase is so common. It is useful whenever an action goes both ways.

Each Other and Its Possessive Form

The normal form is:

each other

But when you want to show possession, use:

each other’s

For example:

They know each other.

But:

They know each other’s families.

The first sentence describes a mutual action.

The second sentence shows that each person knows the family of the other person.

More examples:

• They shared each other’s ideas.
• The players wore each other’s shirts.
• We read each other’s messages.
• The friends visited each other’s homes.

Be careful with the plural-looking form each others. When the phrase is possessive, the standard form is each other’s. Cambridge and the American Heritage Dictionary both give this possessive form.

Each Other vs One Another

These expressions are very close in meaning.

Phrase	Meaning	Example
each other	mutual action	They help each other.
one another	mutual action	They help one another.
each other’s	mutual possession	They use each other’s phones.
one another’s	mutual possession	They respect one another’s ideas.

In modern English, each other and one another are often interchangeable.

So you do not need to worry too much about choosing between them.

For most everyday writing, each other is a simple and natural choice.

Each Other – Google Trends & Usage Data

People may search for eachother or each other because the phrase sounds like one unit when spoken. It can also look like it should be one word because English has many similar words, such as everyone, somebody, and another.

However, the standard written form is still each other.

It is also important not to invent exact Google Trends numbers or country rankings when reliable data is not available. Search interest can change over time, and Google Trends shows relative search interest rather than a fixed number of searches.

Dictionary and language sources show that each other is a normal, established English expression used in both American and British English. Collins lists it as a reciprocal pronoun and provides both American and British usage information.

Corpus-based language resources also treat each other as a multi-word expression rather than a single word.

Historical examples of eachother without a space can be found in older texts, but that does not make it the standard modern spelling. Modern standard English uses each other as two words.

How to Remember the Correct Spelling

Use this simple trick:

Each + space + other

Think of it as two small words:

each | other

Then put them together in a sentence:

We understand each other.

You can also remember the phrase by comparing it with:

one another

Both are made from separate words.

So:

each other ✅

one another ✅

But:

eachother ❌

Conclusion

If you are choosing between eachother or each other, the answer is simple: use each other.

The standard form has two separate words. There is a space between each and other, and there is no hyphen.

This spelling is used in both American and British English. You can use it in school work, university writing, emails, websites, social media, business documents, and everyday messages.

Remember these three forms:

each other = correct

eachother = incorrect in standard modern English

each other’s = correct possessive form

The phrase means that people or things act toward one another or have a mutual relationship. For example, “The two friends help each other” means both friends help the other.

You may sometimes see eachother in old texts or informal writing, but it is not the form you should choose in modern standard English.

When in doubt, keep the words apart:

each other.

That one small space is all you need to remember.
