Etymology: "Cardias" is the plural of "cardia", a term for the upper opening of the stomach, where the gullet meets the stomach. The noun is a learned borrowing from Ancient Greek "kardía", meaning "heart", and it is a doublet of "heart", the two words descending from the same ancient root but reaching English by different routes. The Greek word was also the basis for the anatomical name, so the stomach's upper opening is named after the organ that pumps blood. The link to the heart is less odd than it first looks. Greek anatomists used "kardía" for the region of the body around the upper stomach, and the name stuck to that spot, which sits close beneath the heart. The English word "heart" came through Germanic speech, while "cardia" was taken directly from Greek into scientific Latin and then English, which is why the two look so different despite sharing a source. The word may also be related to "core", though that connection is less certain.
