What term refers to pairs like "each other" or "one another" in grammar?

The correct answer, reciprocal pronouns, refers to pronouns that express a mutual relationship between two or more subjects. Phrases like "each other" and "one another" are used to indicate that the action of the verb in a sentence is reciprocated among the subjects. For instance, in a sentence like "They helped each other," the action of helping is mutual, showcasing how reciprocal pronouns function to illustrate this relationship.

Understanding reciprocal pronouns is crucial because they highlight interactions involving collaboration or mutual exchanges, enriching the clarity and depth of sentence structures in English grammar. Note that intensive pronouns, reflexive pronouns, and subjective pronouns serve different roles in a sentence and do not represent the mutual relationship that reciprocal pronouns do.
