Express a reciprocal relationship

Each other vs. One another 


two holding handsEach other like all pronouns refers back to a noun that comes before it (an antecedent).  However, because it is a reciprocal pronoun, it refers to two nouns or a group noun. It expresses what one person feels toward or does for the other; the other feels or does the same in return.


Sophie loves Jim and Jim loves Sophie.

Sophie and Jim love each other.  (refers to subject)

Sophie and Jim each love the other.

Each person loves the other person.

Occasionally, they get angry at each other.   (refers to subj. pronoun)

Occasionally, they each get angry at the other.

Occasionally, each gets angry at the other.

We have to protect them from each other.   (refers to obj. pronoun)

We have to protect each of them from the other.


Sophie and Jim² believe that each other is wrong.  (refers to subject of the main clause) 

*Each other is wrong.  (missing antecedent)


Our family loves each other.

After a fight, each person apologizes to the others.


two holding handsOne another expresses the same idea of reciprocity  ("one and another").   However, some people use each other for two people and one another for more than two. Other people use each other and one another in the same contexts. This difference is disputed (not accepted by all.)


Sophie loves Jim and Jim loves Sophie. 

Sophie and Jim love one another¹.

~One person loves another person.  (unclear meaning)


Occasionally, they get angry at one another.

~One person gets angry at another(unclear meaning)


We have to protect them from one another.


*Sophie and Jim believe one another³ is wrong.

*One another is wrong.


Our family loves one another.

After a fight, everyone apologizes to one another.


*not used / ~unclear meaning, awkward usage, requires a particular context

reciprocal (Adj) – given, done, felt in return, mutual (A-B and B-A)

¹Each other, one another: "Two people look at each other, More than two look at one another. Either phrase may be used when the number is indefinite: We help each other. We help one another." —Associated Press (2016)

²"Sophie and Jim" are antecedents of "each other". That is to say that the nouns/names are mentioned first so that we know who "each other" refers to.

³One another ("one and the other") This expression is not used as the subject of a clause, nor is it used as the subject of a subordinate clause. However, the expression "each other" does occur, perhaps informally, as the subject of a subordinate clause. They think that [each other is cheating].

(Huddleston 17 §4)

(Each member of our family loves every member of the family.)

Chris, Pat and Robin protect one another.

The staff collaborates with one another.

(As the boys grow, each gives his clothes to the younger child.)

At dinner, we pass bread to one another.

We sit next to one another.

The villagers handed buckets of water to one another to put out the fire.

collaborate (V) – work with





Reciprocal Pronoun Agreement

Express two or more entities with plural nouns



Plural and Singular Exceptions


Because a reciprocal pronoun involves two or more entities (people, things, concepts), the noun forms are usually plural. Similarly, the genitive (possessive) noun is also usually plural (unless it is a noncount noun).


All love each other. 


The husband and wife get angry at each other. 



We know each other's experiences.  (both count and non-count)

We know the experiences of each other.

We know each other's names.  (the names differ)



However, a few words that are singular in form may express two or more entities. This is true for indefinite pronouns everyone, everybody, none and for collective pronouns family, staff, team, and so on.


Everyone loves each other. 

(Everyone "in general" is an indefinite pronoun.)

The couple gets angry at each other. 

(The focus is on the individuals of the group noun.)


We know each other's experience. (both count and non-count)

We know the experience of each other.

We know each other's name. (e.g., they share a last name)



Also see Unusual Singular/Plural Nouns—plural in form but singular in agreement.





Genitive Reciprocal Pronouns

Express possession, relationship or traits



Each other's / One another's


Each other takes the genitive (or possessive) form, which is written with an apostrophe plus s.  While the antecedent (the noun that it refers back to) may be two plural nouns, the reciprocal pronoun is singular.


Sophie and Jim like each other's companionship.   (plural verb)

Sophie and jim like the companionship of each other. "of"

A counselor advises¹ the group about each other's responsibilities. 


Sophie and Jim dispute each others' rights. (misplaced apostrophe)


One another also takes the genitive form, which is written with an apostrophe plus s.  Even though the antecedent is plural, the reciprocal pronoun is singular in its genitive (possessive) form.


Sophie and Jim like one another's companionship.   (plural verb)

Sophie and jim like the companionship of one another. "of"

A counselor advises the group about one another's responsibilities. 


Sophie and Jim dispute one anothers' rights. (misplaced apostrophe)


¹warn__about each other, protect__from each other, introduce__to each other, confine___to each other (Huddleston 279)

Grammar Notes(disputed usage)

Traditional Grammar and Current Description



Each other / One another


Each other, one another Two people look at each other, More than two look at one another. Either phrase may be used when the number is indefinite: We help each other. We help one another. —Associated Press (2016)

"Traditionalists use each other when two things or people are involved, one another when more than two are involved."—The Chicago Manual of Style 278 (2010)

Usage authorities have traditionally suggested that each other should refer to two people or entities <John and Bob helped each other>, one another to more than two <all of them loved one another> ... Careful writers will doubtless continue to observe the distinction, but no one else will notice.  (Language Change Index (i.e. for more than two items) Stage 4.) —Garner (2009)

"Use each other in sentences involving two subjects and one another in sentences involving more than two."—Lunsford (1999)

As mentioned by Merriam Webster, "Actually the prescriptive rule goes back even farther…"  Ayers (1881), Goold Brown (1851), T. O. Churchill (A New Grammar of the English Language, London 1823)

Fowler (1926) notes that some writers follow the rule but goes on to state that "the differentiation is neither of present utility nor based on historical usage; the old distributive of two as opposed to several…would doubtless have survived if its special meaning had been required."—Burchfield (2004)


Each other and one another mean the same... Each other and one another are not used as subjects (though this occasionally happens in subordinate clauses in very informal speech).—Swan 171

We conclude that the rule restricting each other to two and one another to more than two was cut out of the whole cloth. There is no sin in its violation. It is, however easy and painless to observe if you so wish.—Merriam-Webster 378  

If each other is by now a fully established pronoun, there is no grammatical reason it could not be the subject of a clause, but it is simply not so used. Perhaps uncertainly about the number of the verb is a deterrent.—Merriam-Webster 378

One Another: There Will Always Prove to Be a Difference. But the belief is untenable, as can be seen from the following departures from the 'rule": (each other used to refer to more than two)...—Burchfield and Fowler "each"

The reciprocal pronouns each other and one another are used when the verb's meaning applies mutually between two or more people or groups of people, as in [examples]...—Aarts 50

Family Relay Team

passing a baton

Four Brothers Form a Team

The four Moore brothers are a remarkable 4X100m relay team. James and William who are twins, age 21, first became involved in track and field in high school.  They trained together and went on to win several 100m and 200m sprint events. Their two younger brothers Harry, age 19, and Donald, age 18, weren't especially interested in track and field, but when James and William encouraged them, they began sprinting too. They also found themselves to be gifted runners.

The following spring, the older twins encouraged the younger brothers to participate with them in an upcoming 4X100m relay race, and they agreed. The two older bothers helped the younger brothers to improve their running times and their baton passing skills. As a result, the Moore brothers not only won that relay but went on to win four more and broke one state record in the 4X100 relay. Currently all four have track scholarships and are attending different colleges and doing well on their respective track teams.
