stereo
UK: ˈstɛrɪəʊ | US: ˈstɛrioʊ
n. 1. A sound system that reproduces audio using two or more independent channels to create spatial effects.
n. 2. (Colloquial) Short for "stereophonic" or "stereoscopic."
adj. Relating to three-dimensional perception or sound reproduction.
The word "stereo" originates from the Greek prefix "stereo-" (στερεός), meaning "solid" or "three-dimensional." It was first used in English in the 19th century in scientific terms like "stereochemistry" and "stereoscope." By the mid-20th century, it became shorthand for "stereophonic sound," emphasizing the spatial depth of audio reproduction. The morpheme preserves its original Greek meaning of solidity, reflecting the word's association with multidimensional perception.
