Etymology: "Empyemata" is the plural of "empyema", a medical term for a collection of pus trapped in a body cavity, most often the chest. The singular comes from Ancient Greek "empúēma", meaning "gathering" or "abscess", formed from "en" ("in") and "púon" ("pus"), so the word literally describes something gathering inside the body. Greek physicians used it for this kind of pus collection, and the Latinised plural "empyemata" keeps the Greek-style ending that scientific writers preserved for technical terms.
