Reciprocal verbs are verbs that express a mutual action or relationship between two or more subjects. In these constructions, the subjects perform the action on each other. For example, in the sentence "They hugged each other," the verb "hugged" indicates that both subjects are involved in the action reciprocally. In many languages, reciprocal actions can be indicated using specific pronouns or verb forms. In English, phrases like "each other" or "one another" are commonly used. In languages like Spanish or French, reciprocal verbs may have unique conjugations or reflexive pronouns to convey the same meaning.
