What Do One Another” and “Each Other” Mean?
Both one another and each other are pronouns used to show mutual action or relationship between subjects. They fall into the category ofreciprocal pronouns, meaning they describe actions that are performed and received by the same group of people.

Traditional Grammar Rule
According to traditional grammar, the rule is straightforward
