Reciprocal Pronoun

A reciprocal pronoun is used to indicate that two or more people are carrying out or have carried out an action of some type, with both receiving the benefits or consequences of that action simultaneously. Any time something is done or given in return, reciprocal pronouns are used. 

There are only two reciprocal pronouns.

• Each other
• One another

Use:

There must be two or more people, things or groups involved (so we cannot use reciprocal pronouns with I, you [singular], he/she/it).

When you want to refer to two people, you will normally use “each other.”

When referring to more than two people, you will normally use “one another.”

Example:

Maria and Juan kissed each other at the end of the ceremony.

The students congratulated one another after giving practice speeches.
