Etymology: The word is a hybrid built from Latin and Greek parts: "quadra-" comes from Latin "quadra" (a square, or four), and "-phonic" comes from Greek "phōnē" (sound, voice). Put together, the pieces literally mean "four-sound," which is exactly what the technology delivered: four separate channels of audio, one routed to each corner of a room. The "quadra-" element is the same one behind words like "quadrant" and "quadrilateral," so the number four is baked into the name itself. The term belongs to the 1970s, when consumer hi-fi makers tried to move beyond ordinary stereo, which used just two channels. Because it is a modern technical coinage built from classical building blocks, the ancient Romans and Greeks never encountered it; they supplied only the separate parts. The word also has a spelling variant, "quadraphonic," which keeps the same pieces but drops the "i" before "ph." Both forms are in use, and the variant with "quadri-" simply leans more heavily on the Latin prefix "quadri-," meaning "four-fold."
