"Each Other" Versus "One Another"

Is there actually a difference?

Grammarians Disagree About “Each Other” and “One Another”

Since then many grammarians have weighed in, some accepting the rule, others rejecting it. Even today, there isn’t agreement. Some sources that accept it are Garner’s Modern American Usage, and The Grammar Bible, by Michael Strumpf and Auriel Douglas. Some that don’t are the second edition of Fowler’s Modern English Usage, and Grammar Without Grief, by Martin Steinmann and Michael Keller.

There are even sources, such as Ronald Wardhaugh’s Understanding English Grammar, that propose a version of the rule that goes like this: Use “one another” or “each other” when you’re talking about more than two people, but when you’re just talking about two people, use “each other.” That rule will never catch on. People don’t like rules that say option A is available in situation A, but option B is available in situation B and situation A. They prefer clean, two-way distinctions: option A in situation A; option B in situation B; end of story.

“Each Other” and “One Another” Are Often Interchangeable

Despite these rules, both “each other” and “one another” had been used to refer just to two people, and to more than two, hundreds of years before anyone tried to force a meaning distinction on them. The Oxford English Dictionary gives this quotation from Shakespeare, with “one another” referring to two people: “When we are married, and have more occasion to know one another.” MWDEU has this example from Samuel Johnson, with “each other” referring to more than two people: “Sixteen ministers who meet weekly at each other’s houses.” As MWDEU puts it, “the rule restricting ‘each other’ to two and ‘one another’ to more than two was cut out of the whole cloth.”  For some more informative discussion of this issue, read Gabe Doyle’s post on “each other” and “one another” on his blog, Motivated Grammar.  

The Safest Choice Is to Follow the Rule

Since there never was any historical support for this rule, but since there are people who believe in it today, should you follow it? Personally, I’d say no, but the good news is that it’s an easy rule to follow if you choose to. Unlike using “whom” or saying “It is she,” limiting “each other” to two people and “one another” to more than two isn’t going to make your writing sound unnatural. Both sound fine in either situation, whether you’re observing or ignoring the rule.

Don’t Use “Each Other” or “One Another” as a Subject

While we’re on the subject of “each other” and “one another,” we do recommend following one restriction on their use. Specifically, don’t use them as the subject of a clause. For example, suppose Bill thinks Ted is awesome, and Ted thinks Bill is awesome. How could you write that in a single sentence? “Bill and Ted think each other are awesome”? “Bill and Ted think one another is awesome”? No. People do write sentences like that, and you may have heard people speak them, and you may have even spoken them yourself—I know I have. But it still sounds awkward, for reasons that are unclear.

MWDEU notes that “each other” as a subject hardly ever occurs in edited writing, and suggests that it might be because of confusion over whether to use a singular or a plural verb. It just goes to show that even when there is a logical need for a particular word, there is no guarantee that a word will be created to meet that need. This is especially frustrating, given all the words that are created when there isn’t a logical need for them, such as irregardless and conversate. The best you can do in this situation is to use what the Cambridge Grammar of the English Language calls the “split reciprocal” construction, and say “Bill and Ted each think the other is awesome.”

Compound Possession

That’s all for reciprocal pronouns, but I do have one last thing to say about Bill and Ted’s Excellent Adventure: The title is a great illustration of the rule for compound possession, which I discussed in episode 75!

“Each Other” Is Always Two Words

And finally, one more note for the people who are just learning English. “Each other” is always two words.
