Each Other or One Another? The Complete Guide to Correct Usage
Many English learners and even native speakers stop and think before writing each other or one another. At first glance, both phrases seem the same. However, people often worry about grammar rules, exam answers, and professional writing standards. As a result, they search for “each other or one another” to avoid mistakes.
This confusion exists because teachers, grammar books, and websites sometimes give different explanations. Some say each other is for two people, while one another is for more than two. Meanwhile, others say the rule no longer matters. Therefore, writers feel unsure about which phrase sounds correct.

This article clears that confusion once and for all. It gives a quick answer, explains the origin, compares British and American English, and shows real examples. By the end, you will confidently know when to use each other and when one another is the better choice.
Each Other or One Another – Quick Answer
- Each other → Traditionally used for two people or things.

However, in modern English, both are often interchangeable, especially in everyday writing. Still, formal writing may follow the traditional rule.
The Origin of “Each Other” and “One Another”
Originally, each other entered English in the 14th century. It described a mutual action between two people. Later, one another appeared to show the same idea but among many people.
At that time, English grammar was strict. Therefore, writers clearly separated the two phrases. Over time, however, spoken English changed. Gradually, people began using both phrases freely. As a result, modern dictionaries now accept both forms in most situations.
