Should I Use Each Other or One Another?
Posted by Jake Magnum | October 26, 2017 | This or That?
While determining whether to use the phrase each other or one another is straightforward, some people have a tendency to either use them interchangeably or to always use one regardless of the context.
The rule for using these terms is simple. When discussing only two entities, one another should be used, as in “How well do you two know one another?” Many people would not think anything of it if you instead said, “How well do you two know each other?” but this second question is technically incorrect.
When discussing more than two entities, the term each other should be used, as in, “All the children played nicely with each other.” Again, many would not notice the mistake if you were to say “All the children played nicely with one another,” even though this second sentence is not quite correct.
