intermediary

This term describes a neutral third party that facilitates communication or negotiation. It carries a connotation of professionalism and strategic positioning, often implying that the parties involved cannot or will not communicate directly due to conflict, status differences, or technical barriers. When used as an adjective, it describes the function of a bridge or a medium. It is more formal than words like middleman and is frequently employed in legal, diplomatic, and corporate contexts to denote a structured process of mediation.
