stereo

stereo: [19] Greek stereós meant ‘solid’. The earliest English compound noun formed from it was stereometry [16], a mathematical term denoting the measurement of solid or threedimensional objects. This was followed by stereographic [17], stereotype [18] (coined in French and originally used for a ‘solid’ printing block; the metaphorical ‘unvaried or conventional image’ emerged in the middle of the 19th century), stereoscope [19] (a viewer for producing ‘solid’ or three-dimensional images), and stereophonic ‘producing three-dimensional sound’ [20]. Stereo was used in the 19th century as an abbreviation for stereotype and stereoscopic; its use for stereophonic dates from the early 1950s.
