Etymology: Cephalometrics is a compound built from two Greek-derived parts. The first, "cephalo-", comes from the Greek "kephalē", meaning "head", and it appears in a range of scientific coinages, from "cephalopod" (a creature whose feet sit on its head) to "cephalic". The second, "metrics", comes from the Greek "metron", meaning "measure", and gives English words like "geometry" and "thermometer" their final syllable. Put together, the word describes the measurement of the head, and in practice the skull, which is why it is used in anthropology and medicine for studies of skull dimensions. Because both parts are classical, the compound is a technical coinage made from ancient roots rather than a term that existed in antiquity, so the Greeks themselves would not have recognised it as a single word.
