A student once submitted an essay with the sentence: “We should respect eachother.”
The teacher circled one word in red. The student felt confused. It looked correct. It sounded correct. So why was it wrong?
This is why many students, bloggers, content writers, and English learners search for eachother or each other every day.
The confusion is simple: should it be one word or two? If you write emails, academic papers, social posts, or professional content, this small spacing mistake can hurt your credibility.
In this guide, you will learn the correct form, the grammar rule, synonyms, examples, quiz practice, Reddit discussions, and how to use each other confidently in real writing.
Quick Answer
✅ Correct: Each other
❌ Incorrect: Eachother
Each other is a reciprocal pronoun. It shows that two or more people do something to one another.
Example:
- They respect each other.
- The friends helped each other.
Major references like the Merriam-Webster Dictionary and the Oxford English Dictionary confirm that each other is always written as two words.
“Eachother” is a common spelling mistake.
The Origin of Each Other
The phrase comes from early usage in the English language.
It developed as a grammatical structure combining:
- “Each” (individual)
- “Other” (the second person)
Over time, it remained two separate words because it functions as a grammatical phrase, not a compound noun.
That is why it never became one word.
British English vs American English Spelling
Good news: there is no difference.
In both:
- United States
- United Kingdom
The correct form is each other.
There is no regional spelling variation.
| Region | Correct Form |

| US | Each other |

| Global | Each other |
Which Spelling Should You Use?
Always use each other.
Never write:
- ❌ eachother
Spellcheck tools like Grammarly will flag “eachother” as incorrect.
If you are writing:
- Academic essays → each other
- Business emails → each other
- Social media → each other
- Professional reports → each other
There is no exception.
