From Wikisource

GRAMOPHONE (an invented word, formed on an inversion of “phonogram”; φωνή, sound, γράμμα, letter), an instrument for recording and reproducing sounds. It depends on the same general principles as the phonograph (q.v.), but it differs in certain details of construction, especially in having the sound-record cut spirally on a flat disk instead of round a cylinder.
