Is Eachother One Word? Each Other vs. Eachother Explained

Each other is written as two separate words. The joined spelling eachother is incorrect in standard English.

Use each other when two or more people, animals, groups, or things do something to or for the others. When showing possession, use each other’s with an apostrophe and an s.

Is Each Other One Word or Two?

Each other is always two words. A space should appear between each and other, no matter where the phrase appears in a sentence.

Correct: The friends called each other.
Incorrect: The friends called eachother.

The incorrect spelling may look natural because the words are commonly spoken together. However, they have not combined into a single word.

The same spelling applies when the phrase follows a preposition or takes a possessive ending:

They sat beside each other.
They remembered each other’s birthdays.

What Does Each Other Mean?

Each other is a reciprocal pronoun. It describes an action, feeling, or relationship that goes in more than one direction.

For example:

Amy and Leo helped each other.

This means Amy helped Leo and Leo helped Amy. The action was mutual.

The phrase can refer to two people or things:

The sisters trust each other.
The two dogs followed each other.

It can also refer to a larger group:

The players encouraged each other.
The neighbors looked after each other during the storm.

The action does not have to be friendly or positive. Two people can disagree with, compete against, or criticize each other.

How to Use Each Other in a Sentence

Each other often appears after a verb describing a shared action or relationship:

We understand each other.
The children copied each other.
The companies support each other.

It can also follow prepositions such as to, with, for, from, and at:

They spoke to each other.
The students shared notes with each other.
The players stood across from each other.

Do not confuse each other with a reflexive pronoun such as themselves. The two forms express different relationships:

Ben and Chloe looked at each other. Ben looked at Chloe, and Chloe looked at Ben.
Ben and Chloe looked at themselves. Each person looked at their own reflection or appearance.

Use each other when the action passes between people or things. Use themselves when the action returns to those performing it.

Is Each Other’s Correct?

Each other’s is the correct possessive form. The apostrophe and s show that something belongs or relates to the people or things involved.

They borrowed each other’s books.
The students reviewed each other’s essays.
The team members learned each other’s names.

The form remains each other’s even when the sentence refers to more than two people. Do not add a regular plural ending to each other.

Form	Correct?	Example or Correction
each other	Yes	They helped each other.
each other’s	Yes	They respected each other’s opinions.
eachother	No	Write each other.
eachother’s	No	Write each other’s.
each others	No	Write each other.
each others’	No	Write each other’s.

Each Other vs. One Another

Each other and one another have nearly the same meaning. Both describe a reciprocal action or relationship.

The two friends helped each other.
The two friends helped one another.

A traditional rule says that each other should be used for two people or things and one another for three or more. This distinction is not strictly followed in modern English. Either expression can normally refer to two people or a larger group.

The classmates helped each other prepare.
The couple cared for one another.

Both sentences are standard. One another may sound slightly more formal, but the choice usually depends on which phrase sounds more natural in the sentence.
