English learners, students, and even professional writers often search for “each other or eachother” because both forms appear online, in messages, and on social media.
At first glance, they look almost identical, which creates real confusion. People want to know which spelling is correct, which one sounds natural, and which one should be used in formal
writing. This confusion matters because using the wrong form can make writing look careless or unprofessional, especially in exams, emails, articles, or business communication. This article solves that problem clearly.
You will get a quick answer, history, British vs American usage, common mistakes, real life examples, trend insights, FAQs, and expert advice all written in simple, clear English.
Eachother or Each Other: Quick Answer
Each other is the only correct spelling in standard English.
Eachother (written as one word) is incorrect and should not be used in formal or professional writing.
Correct examples:
- They help each other every day.
- The two teams respect each other.
Incorrect example:
- ❌ They help eachother every day.
In short, always use each other as two separate words.
The Origin of Eachother or Each Other
To understand why only each other is correct, we need to look at its origin.
Historical Background
The phrase each other comes from Middle English. It is made from two separate words:
- each (meaning every one of two or more people or things)
- other (meaning the second or remaining person or thing)
Together, they form a reciprocal phrase, meaning an action is shared between two or more people.
Why “Eachother” Exists
The spelling eachother appeared much later, mainly because:
- People say the phrase quickly in speech
- In casual writing, words are often joined
- Digital communication encourages shortcuts
However, English dictionaries and grammar guides have never accepted “eachother” as a correct form. It remains a spelling error, not an alternative version.
British English vs American English Spelling
Unlike many spelling debates, each other does not change between British and American English.
British English
- Correct form: each other
- Incorrect form: eachother
Example:
- They support each other during difficult times.
American English
- Correct form: each other
- Incorrect form: eachother
Example:
- The players trust each other completely.
- each other or eachother.
Comparison Table
| Feature | British English | American English |
| Correct spelling | each other | each other |
| Incorrect spelling | eachother | eachother |
