Is it each other or eachother? The correct spelling is each other, written as two separate words. Eachother is incorrect in standard English. We use each other when two or more people or things perform an action toward one another or share a mutual relationship.
For example, you should write, “The two friends help each other,” not “The two friends help eachother.” The phrase is common in everyday conversation, emails, school assignments, professional writing, and social media.
This spelling can be confusing because many English expressions combine into one word over time. However, each other remains an established two word phrase. It is often called a reciprocal pronoun because it shows that an action or feeling goes both ways.
In this guide, you will learn the correct spelling, meaning, grammar rules, and practical uses of each other. You will also see common mistakes, real life examples, and simple tips to help you remember the difference.
What Is the Difference Between Each Other and Eachother?
Each other is the correct spelling. It is a two word expression used to show a mutual action, feeling, or relationship. Eachother is not accepted as a standard spelling in modern English.
Examples:
- Correct: The students help each other.
- Incorrect: The students help eachother.
- Correct: We respect each other.
Remember: Always write each other as two separate words.
Each Other vs Eachother: Quick Answer
The rule is simple:
- Each other: Correct. It shows a mutual action or relationship.
- Eachother: Incorrect in standard English. Do not join the two words.
Meaning: When people help each other, they help one another. When friends trust each other, the trust goes both ways.
Example: “My cousins always support each other.”
Use each other in schoolwork, business writing, formal documents, and everyday messages.
What Does Each Other Mean?
Each other means one another. It describes an action, feeling, or relationship shared between two or more people or things.
It often appears with verbs such as help, know, understand, respect, love, and support.
Definition of Each Other
Each other is a reciprocal expression. It shows that the people or things involved act toward one another.
Examples:
- The children shared their toys with each other.
- The two colleagues respect each other.
- We understand each other well.
- The teams learned from each other.
In each example, the action is mutual. The people involved are connected through the same action or feeling.
How to Use Each Other in a Sentence
Place each other where it fits naturally after the verb or preposition.
Examples:
- They called each other after the meeting.
- The neighbours often talk to each other.
- We bought gifts for each other.
- The players congratulated each other.
The exact position depends on the sentence, but the spelling stays the same.
The Origin of Each Other
The expression each other developed from two common English words: each and other.
- Each refers to individual members of a group.
- Other refers to a different person or thing.
Together, they express a relationship in which people or things act toward one another.
Over time, each other became a common way to describe mutual actions and feelings. Although English contains many compound words written as one word, this expression is still conventionally written as two words.
There is no standard spelling change that makes “eachother” correct. In edited English, keep the words separate.
British English vs American English
There is no spelling difference between British and American English for this expression. Both use each other as two words.
| British English | American English | Example |
| Each other | Each other | They help each other. |
| Each other | Each other | We understand each other. |
| Each other | Each other | The friends spoke to each other. |
| Each other | Each other | The teams support each other. |
Does the Meaning Change by Region?
No. The expression has the same basic meaning in both varieties of English.
British and American writers use each other in everyday conversation, academic writing, emails, books, and professional communication.
For international writing, always use “each other.” It is the standard spelling across English varieties.
Which Version Should You Use?
Use each other in every standard English context. The one word spelling eachother is not the correct alternative in formal or edited writing.
In the United States
Write each other in school assignments, emails, business documents, and online content.
Example: The team members trust each other.
In the United Kingdom
The same rule applies in British English.
Example: The neighbours often help each other.
In Canada and Australia
Use each other in both countries. The expression does not change according to regional spelling preferences.
In International Writing
If your audience includes readers from different countries, use each other. It is clear and widely understood.
In Academic Writing
Use each other when describing mutual actions or relationships between people, groups, or objects.
Example: The researchers compared the two methods with each other.
A smoother alternative may be “The researchers compared the two methods,” depending on the sentence.
In Business Writing
Use each other to describe teamwork, communication, or shared responsibilities.
Example: Team members should communicate with each other regularly.
Final rule: if your writing is formal or informal, the correct spelling remains each other.
Common Mistakes: Each Other or Eachother
Many writers accidentally join the two words because they sound like one phrase when spoken. Here are common mistakes to avoid.
| Incorrect | Correct | Explanation |
| They help eachother. | They help each other. | The expression uses two words. |
| We know eachother well. | We know each other well. | Keep the words separate. |
| The students respect eachother. | The students respect each other. | The action is mutual. |
| They gave gifts to eachother. | They gave gifts to each other. | The phrase remains two words. |
Common Mistake: One Anothervs Each Other
Each other and one another often have the same meaning.
Examples:
- The two friends support each other.
- The two friends support one another.
Both sentences are correct.
Some traditional grammar guides suggest using each other for two people and one another for more than two. In modern English, however, this distinction is not a strict rule.
Memory Tip
Think of the phrase as two separate ideas: each person and the other person.
When you write it, keep both words separate: each other.
