There are only two reciprocal pronouns: each other, one another. The reciprocal pronouns are used to express a relationship in which something is done by each of two or more parties towards the other or others. They refer mostly to people, but they can also be applied to animals or things. A plural subject is always used as more than one person or thing are involved.

 

Each other is usually used when writing or speaking about two people or things. For more than two people or things, one another is generally used.

  • Their parents often argue with each other.
  • The few puppies chased one another across the field.
 

Reciprocal pronouns as objects of a verb.

  • This is the tenth year that Jack and Jim have known each other.
  • Before they began talking, they bowed to one another.
 

Reciprocal pronouns following a preposition(at, with).

  • No one knows why they are shouting at each other.
  • They realized it would be much easier if they all cooperated with one another.
 

Reciprocal pronouns have the possessive case.

  • The two old monkeys are seen scratching each other's heads.
  • When the two groups met, they started shaking one another's hands.
