Did you know?

Since inter- means "between, among", an intermediary is someone who moves back and forth in the middle area between two sides—a "go-between". Mediator (which shares the medi- root) is often a synonym, and so is facilitator; broker and agent are often others. Thus, a real-estate broker or agent shuttles between a house's buyer and seller, who may never even meet each other. Financial intermediation is what happens when you put money in a bank or investment firm, which then invests it in various companies; if you want, you can instead cut out the intermediary and invest the money directly in companies of your own choosing.
