Eachother or Each Other: Which Spelling Is Correct?

Have you ever typed eachother and wondered whether it should be written as one word? You are not alone. This small phrase causes frequent confusion because English contains many compound words that combine into a single word. However, each other follows a different pattern.

The correct spelling is each other, with a space between the two words. The form eachother is incorrect in standard English. You will see each other in school assignments, emails, business writing, conversations, and formal documents.

Understanding this difference is simple once you know how the phrase works. Each refers to individual members of a group, while other identifies another member of that group. Together, they express a mutual relationship or action.

This guide explains the meaning, origin, spelling, common mistakes, British and American usage, and practical examples of each other.

Eachother or Each Other – Quick Answer

The correct spelling is each other, written as two separate words. Eachother is not considered standard English.

The phrase usually describes a mutual action or relationship between two or more people or things.

• Correct: They helped each other.
• Incorrect: They helped eachother.
• Correct: We respect each other.
• Incorrect: We respect eachother.

A useful trick is to remember that each and other can function independently. Therefore, keep the space between them.

Meaning of Each Other

Each other means that people or things perform an action mutually or toward one another. It commonly appears with verbs involving relationships, communication, assistance, trust, and shared actions.

For example, “The students helped each other” means every student helped another student. Similarly, “They understand each other” describes mutual understanding.

The phrase can describe relationships, actions, skills, control, ownership, and abstract qualities when the context shows a mutual connection.

Examples:

• The players encouraged each other.
• The partners trusted each other.
• The teams competed against each other.
• The children shared their toys with each other.

Why People Misspell Each Other

People often write eachother because English contains many words that combine two smaller words. For example, address, success, and necessary contain repeated letters, while words such as “someone” and “everybody” are written as single words.

Fast typing can also remove spaces. When people type quickly, each other may accidentally become eachother.

Another reason is pronunciation. In normal speech, the phrase sounds connected, so writers may assume it should also appear as one word.

Remember this simple rule: each other always needs a space in standard English.

Origin of Each Other

The phrase each other comes from older Germanic forms of English rather than Latin. Each developed from Old English forms related to the idea of “every one” or “each individual,” while other comes from an Old English word meaning “the second” or “different.”

Unlike some English vocabulary derived from Latin, each other does not have a Latin root. Its history reflects the Germanic foundation of English.

Over time, English speakers used the two words together to express reciprocal or mutual relationships. The modern spelling has remained separated into two words.

British English vs American English

There is no spelling difference between British and American English for this phrase. Both varieties use each other as two words.

English Variety	Correct Form	Example
American English	each other	They support each other.
British English	each other	They support each other.
Canadian English	each other	We understand each other.
Australian English	each other	They helped each other.

Therefore, changing from British to American English does not change this spelling.

When to Use Each Other

Use each other when describing a mutual action, feeling, relationship, or interaction.

Essays and Assignments

Work Reports

The phrase can also appear in formal or legal language.

Common Mistakes With Each Other

The most common mistake is joining the words together.

Incorrect	Correct
eachother	each other
Eachother helped us.	Each other helped us.
They trust eachother.	They trust each other.
We support eachother.	We support each other.

There is also an important point about double letters. The phrase each other does not contain a double “s.” Words such as success and address have repeated letters, but that spelling pattern does not apply here.

Typing quickly can also cause writers to forget the space. Always check the phrase during proofreading.

Everyday Examples of Each Other

Email

These examples show that each other works naturally in both informal and formal situations.

Each Other in Different Contexts

The phrase can describe many kinds of mutual relationships. The surrounding verb tells you exactly what the relationship involves.

Context	Correct Sentence	Incorrect Sentence
Objects	The two machines depend on each other.	The two machines depend on eachother.
Skills	The students improve each other’s skills.	The students improve eachothers skills.
Legal terms	The parties agreed to notify each other.	The parties agreed to notify eachother.
Daily speech	We always help each other.	We always help eachother.
Relationships	They trust each other.	They trust eachother.
Communication	The teams contacted each other.	The teams contacted eachother.

Notice the possessive form each other’s when something belongs to or is associated with each person in the relationship.

Each Other vs. One Another

Each other and one another often have the same meaning. Both can express a mutual action.

For example:

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

Traditional grammar sometimes suggested using each other for two people and one another for more than two. However, modern English does not consistently maintain that distinction.

In everyday writing, each other is extremely common and works naturally for both two-person and group relationships.

How to Remember the Spelling

Use a simple mental picture: two separate people helping one another.

The phrase contains two separate words:

EACH + OTHER

Keep the space just as you would keep two people standing apart.

You can also remember this sentence:

We help each other.

If you can see each and other as separate ideas, you are less likely to combine them while typing.

Most importantly, do not try to apply the spelling patterns of words like address or success to this phrase. Each other has no double “s.”
