Morphology

polygraph = graph (semi-transparent) = poly + graph

The structure poly- + graph is recognizable, but the specific meaning of a medical recording instrument is specialized rather than fully predictable.

Etymology

The word polygraph comes from two simple parts: poly meaning 'many' and graph meaning 'to write' or 'to record'. Think of it as a machine that 'writes' many body signals at the same time, so a medical polygraph records pulse, breathing, and other vital signs.
