Los dos pronombres recíprocos en inglés son each other y one another. En la gramática más tradicional, each other se utiliza para identificar sólo a dos personas en una acción mutua, mientras que one another describe a más de dos personas.
Sin embargo, debemos recalcar que en el inglés moderno esta "regla" es menos comúnmente aplicada pudiendo utilizarse each other y one another indistintamente.
