Eachother or Each Other: Easy Grammar Guide

A tiny space can make a big difference in English. If you have ever stopped while writing and wondered whether “eachother or each other” is correct, you are not alone. This is a common spelling question for students, English learners, bloggers, and professionals.

The good news is simple: “each other” is always correct in standard English. “Eachother” is incorrect. The phrase has two separate words and should not be joined together. Cambridge Grammar specifically notes that each other is written as two words with no hyphen. 

People often make this mistake because English has many words that combine into one, such as someone, anyone, and everybody. 

Also, when spoken quickly, “each other” can sound almost like one word. This makes the spelling easy to forget.

In this guide, you will learn the correct form, its meaning, its history, British and American usage, common mistakes, real-life examples, and search trends. By the end, you will know exactly when and how to use each other.

Eachother or Each Other – Quick Answer

The correct spelling is each other, two separate words.

❌ eachother > Incorrect
✅ each other > Correct

Each other is a reciprocal pronoun. It shows that two or more people or things act toward one another.

Examples

• We help each other.
• They respect each other.
• The two friends called each other every day.
• The students shared their ideas.
• The teams competed against each other.

Cambridge defines each other as a phrase used when people in a group do something to the others. 

Easy rule

Always write “each other” as two words.

There is no standard English situation where eachother should be written as one word.

The Origin of Eachother or Each Other

The phrase each other has been part of English for many centuries. Merriam-Webster lists its first known use as before the 12th century. 

The phrase combines two ordinary words:

• Each > referring to every individual member of a group.
• Other > referring to a different person or thing.

Together, each other expresses a reciprocal relationship.

For example:

Sarah and Tom help each other.

This means Sarah helps Tom, and Tom helps Sarah.

Over time, English developed many compound words. Words such as anyone, someone, and everybody became single words. This can make each other look natural.

However, each other never became a standard single word. Modern English dictionaries and grammar guides continue to treat it as two words. Cambridge explicitly says that writers should use each other, not eachother. 

Why does “eachother” look correct?

There are two main reasons:

• Fast speech can make “each other” sound like one unit.
• English has many joined words, so writers may assume the same rule applies here.

But spelling must follow the standard form, not the way the phrase sounds.

British English vs American English Spelling

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

Both use:

✅ each other

Both reject:

❌ eachother

So you do not need to change the spelling when writing for readers in the United States, United Kingdom, Canada, Australia, or other English-speaking regions.

English variety	Correct spelling	Incorrect spelling
American English	each other	eachother
British English	each other	eachother
Canadian English	each other	eachother
Australian English	each other	eachother
New Zealand English	each other	eachother
International English	each other	eachother

Cambridge provides both British and American dictionary entries for each other, with the same spelling and meaning. 

What about “one another”?

One another is also correct.

For example:

• They helped each other.
• They helped one another.

The meanings are very similar. Cambridge says there is very little difference between each other and one another, and that each other is more common. 

Which Spelling Should You Use?

The answer is easy: use each other everywhere.

For US English

Use:

The two companies support each other.

For UK English

Use:

The two companies support each other.

Academic writing

Use:

Students should learn from each other.

For business writing

Use:

Our departments work closely with each other.

For social media

Use:

We should always support each other.

You do not need a special American or British spelling.

If you are writing for a global audience, each other is the safest choice because it is standard across English varieties.

Common Mistakes with Eachother or Each Other

Writing “eachother” as one word

❌ They trust eachother.

✅ They trust each other.

This is the most common mistake.

Adding a hyphen

❌ They work with each-other.

✅ They work with each other.

Cambridge states that each other is written as two separate words without a hyphen. 

Using “each others”

❌ They respect each others.

✅ They respect each other.

When possession is needed, use each other’s:

They borrowed each other’s books.

Confusing “each other” with “themselves”

These can have different meanings.

They blamed themselves.

This means each person blamed himself or herself.

They blamed each other.

This means one person blamed another person, and the feeling was mutual.

Thinking “each other” is only for two people

This is another common idea, but modern usage does not require that strict rule. Merriam-Webster notes that the traditional distinction between each other for two and one another for three or more is not consistently followed in actual usage. 

Each Other in Everyday Examples

Knowing the spelling is useful, but knowing how to use the phrase makes your writing much stronger.

Please make sure that all team members communicate with each other.

Another example:

These sentences work well in professional communication.

In News Writing

Or:

The neighboring countries agreed to work with each other.

On Social Media

In Formal Writing

They really understand each other.

These examples show the most common meaning: a mutual action or relationship.

Each Other – Google Trends & Usage Data

Search interest around “eachother or each other” comes mainly from people checking spelling and grammar. The question appears across English-learning, academic, workplace, and online-writing contexts.

Available search-oriented sources commonly identify the United States, United Kingdom, Canada, Australia, India, and other English-learning regions as places where people search for this type of spelling clarification. 

However, Google Trends reports relative search interest, not a fixed number of searches. A value of 100 represents the highest point within the selected comparison and period, so it should not be treated as an absolute search-volume figure. 

General usage pattern

Region	Main reason for searches	Correct form
United States	Grammar and spelling checks	each other
United Kingdom	Grammar and writing	each other
Canada	Writing and education	each other
Australia	English usage	each other
India	English learning and exams	each other
Pakistan	English learning and writing	each other

Searches may increase when students write essays, prepare for exams, or check professional emails. Online posts can also spread eachother, making people wonder whether it is an accepted spelling.

The important point is that search popularity does not change the grammar rule. Dictionaries and grammar references recognize each other as the standard form.
