intermediary

Imagine two kingdoms that have been feuding for generations. They do not want to talk directly to each other, so someone in the middle has to carry messages, help them reach a deal, or calm things down. That is one common use of intermediary: a person or organization that connects two sides that are not dealing with each other directly. A real estate agent, a broker, or even a helpful friend can play that role. The word can also describe a middle stage or middle form, like an intermediary step in a process.

An intermediary is a person, group, or thing that acts as a link between two or more sides. In the most common sense, it refers to someone in the middle who helps people communicate, make a deal, settle a problem, or pass something from one side to another. The core idea is being between others and making a connection that might otherwise be difficult, awkward, or impossible.

In many contexts, "intermediary" suggests some degree of neutrality. The goal is often to help both sides find common ground without fully joining either side. This is common in diplomacy, legal disputes, business deals, and finance. A broker may connect buyers and sellers; an agent may handle communication between parties; a distributor may stand between a producer and a customer. Even in technology, one system can serve as an intermediary between two others.

However, the role is not always about peace-making. In business, an intermediary often earns a fee or commission for helping with a transaction. A travel agent, for example, may arrange services between travelers and providers, while a broker connects one side of a market with another. In those cases, the person or company in the middle is useful precisely because they know how to make the exchange happen.

The word is also used as an adjective. An intermediary stage, step, or form is one that comes between an earlier point and a later one. For example, in science, business, or learning, there may be an intermediary phase before the final result. So the word can describe either a go-between or something that stands in the middle of a process. In both uses, the main idea stays the same: it connects one side, stage, or condition to another.
