Etymology: "Intrahepatic" is a plain modern compound, built from two parts with long histories. The first, "intra-", is a Latin prefix meaning "within" or "inside," which English took directly from Latin. The second, "hepatic," comes from Ancient Greek "hēpatikos," meaning "of the liver," formed from "hēpar," the Greek word for liver. That Greek noun traces back to an ancient Indo-European root shared by many words for the organ, and it passed through Late Latin "hepaticus" before reaching English. English speakers have used "hepatic" since the Middle English period, when it appeared as "epatik." The modern medical sense of "hepatic," meaning relating to the liver, is the one that "intrahepatic" inherits. Adding "intra-" simply specifies that something lies inside the liver, as in an intrahepatic bile duct, which runs within the organ rather than outside it.
