/ˈɑːbɪtə/ – Noun
Definition: trọng tài.
A more thorough explanation: An arbiter is a person or entity with the authority to make a final and binding decision or judgment on a dispute or issue, typically in a legal or contractual context. Arbiters are often appointed to resolve disagreements between parties who have agreed to submit their dispute to arbitration rather than pursuing litigation in court.
Example: The judge acted as the arbiter in the dispute between the two parties, making the final decision on the matter.
