Why is it called a gramophone?

The term "gramophone" comes from the Greek Words "gramma," meaning "letter" or "written," and "phone," meaning "sound." It refers to the device's ability to record and reproduce sound through grooves etched into a disc, which can be thought of as a written representation of sound. The gramophone was a significant advancement over earlier phonographs, which used cylinders to play back sound. Its name emphasizes the technology's focus on sound reproduction and recording.
