Etymology: "Electrographic" is a plain compound: "electro-," the combining form drawn from "electricity," joined to "-graphic," meaning "relating to writing or recording" (from Greek "graphein," "to write"). Put together, the word describes recording or drawing something by means of electrical activity. The combining form "electro-" traces back to "electric," itself from the Latin "electrum," a word for amber, which was prized for the static charge it held when rubbed. "-Graphic" entered English as an adjective ending for things connected with drawing, writing or recording, so "photographic," "telegraphic" and "radiographic" follow the same pattern. The adjective applies the same logic to the bioelectrical and machine signals captured by instruments such as electroencephalographs.
