Etymology: "Amicus" on its own is a clipped form of the Latin phrase "amicus curiae," meaning "friend of the court." The full phrase is the older one, and the single word is simply what remains when lawyers shorten it in everyday speech, much as "amicus brief" is often the name for the filing itself. The Latin "amicus" means "friend," and "curiae" is the genitive of "curia," the Roman senate house, later used for the body that sat in judgment. A friend of the court was therefore someone with no stake in the dispute who could still offer the judges useful help, a role that gave the outsider a recognized place in the proceedings without making them a party to the case.
