go-between

In sociology, a "go-between" is an intermediary who facilitates communication or transactions between two or more parties who do not have direct access to each other. This role can involve carrying messages or acting as a mediator to help opposing sides reach an agreement.1234

Brokers, a type of go-between, possess specialized knowledge or resources that enable them to bridge gaps between individuals or groups. They can control information flow and communication, which grants them a degree of power. This brokerage function is crucial in various contexts, including social networks, political clientelism, and inter-ethnic relations, often acting as cultural translators to reduce misunderstandings and promote social cohesion.2
