Usage
What is an arbitrator? An arbitrator is an independent, impartial third party that works to settle a dispute between two opposing sides, often by making a decision that they both agree to. This process is called arbitration. For a process to be considered arbitration, it must involve an arbitrator, which can be a single person or a team of people. To act as an arbitrator is to arbitrate. Arbitrate can also mean to try to settle a dispute through arbitration, as in If we can’t come to an agreement, we may need to arbitrate. The terms arbitrator and arbitration are especially used in the context of negotiations between businesses and labor unions. When the two sides can’t agree and negotiations are unproductive, they may seek to pursue arbitration by bringing in an arbitrator. An arbitration process in which the arbitrator’s decision must be accepted by both parties is sometimes called binding arbitration—meaning the arbitrator’s decision is final and legally binding. Example: After weeks of negotiations stalled and resulted in an impasse, the two sides agreed to bring in an arbitrator.

Explanation
An arbitrator is someone who helps resolve a dispute. If you and your sibling are butting heads over whose turn it is to clean the bathroom, you may need the assistance of an arbitrator. In legal terms, an arbitrator is the impartial judge of a case settled outside of a courtroom. Their job is to carefully consider both sides and make a decision, without the expense and time involved in going before an actual judge or jury. As a neutral decider whose decision is authoritative, an umpire or referee is another good example of an arbitrator. The Latin root of arbitrator is arbiter, "judge."
