Etymology: This word is a plural, the form you use when there are many heart muscle cells, and its singular is "cardiomyocyte." The singular is built from two Greek-derived parts. The first, "cardio-", comes from Ancient Greek "kardia," meaning heart, a word that traces back to a Proto-Indo-European root for the heart shared with many other European languages. The second, "myocyte," combines "myo-," from Greek "mys," meaning muscle, with "-cyte," from Greek "kytos," meaning hollow vessel or cell. Together they describe a muscle cell of the heart. The term is a modern scientific coinage, assembled in English from Greek building blocks rather than used by the ancient Greeks, who had no concept of individual muscle cells. Its parts were put together on purpose by researchers describing tissue they could now see under the microscope, so the word is a tidy label for a precise anatomical idea.
