Usage

What does mediator mean? A mediator is a person who mediates—helps to settle a dispute or create agreement when there is conflict between two or more people or groups by acting as an intermediary or go-between for those parties. The act or process of mediating is called mediation. Mediation always involves a mediator acting as an impartial third party to guide the communication between the conflicting parties. Sometimes, mediation happens in an informal way. You might act as a mediator for two friends by mediating their argument. But the word is perhaps most commonly used in more specific ways in formal situations, such as when a mediator mediates a labor dispute between a company and its striking employees or when a mediator mediates a divorce for two spouses. When mediation occurs in an official or legal context, such as when it has been ordered by a judge, it is often called arbitration and is performed by an arbitrator. Arbitration usually involves a decision that the parties are bound by. Mediation is typically less formal and usually involves suggestions for settling differences, as opposed to binding decisions. Example: I know you two have your differences, so I’d like to act as a mediator while you talk it out and try to come to an understanding.

Etymology

Origin of mediator

First recorded in 1250–1300; from Anglo-French mediatur, Old French mediatour, from Latin mediātor “go-between, intermediary”; see mediate, -tor

Explanation

A mediator is a person who helps negotiate between two feuding parties. When a married couple is considering getting divorced, they sometimes hire a mediator to help them come to an agreement, and possibly even avoid divorce. The word mediator goes back to the Latin word medius, which means middle. A mediator is supposed to remain in the neutral middle rather than taking one side over another, in order to help both sides resolve a dispute. Mediators negotiate between employers and employees, disputing couples, and in schools helping kids work out their conflicts peacefully rather than fighting on the playground or lunchroom.
