Etymology: "Cardiothoracic" is a plain technical compound, assembled from two Greek-derived combining forms. The first, "cardio-", comes from Ancient Greek "kardía", meaning "heart," a word that traces back through Proto-Hellenic to the Proto-Indo-European root "*ḱerd-", which also gave Latin "cor" (heart) and, through it, English "courage." The second, "thoracic," comes from Greek "thōrax," meaning "breastplate" or "chest," the same word that gave us the chest of the body and the thorax of an insect. Put together, the two parts name the region of the body housing both the heart and the lungs, and the adjective describes surgery performed there. Like many modern medical terms, it is a deliberate coinage built from classical roots rather than a word that existed in ancient Greek or Latin, since the surgical specialty it describes is a modern development.
