Etymology: Kymogram is a plain technical coinage built from two Greek elements. The first, "kymo-", comes from Greek "kyma", meaning "wave" or "swell", the same root behind words like "cyma" in architecture, where it names a moulding with a wavy profile. The second, "-gram", comes from Greek "gramma", meaning "something written or drawn", as in "telegram" or "diagram". Put together, the word describes a record of waves or of any physical quantity that rises and falls over time. The "kymo-" element is the interesting part. Its wave sense makes sense for the instruments this term describes, since early kymographs traced the rising and falling pressure of blood or the motion of muscles onto a moving strip of paper, producing a wavy line. The word therefore names the drawing itself rather than the device that made it.
