The word 'videodisc' is a modern compound formed in the late 20th century from two established English morphemes. The first part, 'video', originates from the Latin verb 'vidēre', meaning 'to see', which entered English via its neuter past participle 'visum' and became associated with visual technology. The second part, 'disc', derives from the Latin 'discus', meaning a round, flat plate, which itself came from the Greek 'diskos' (a thing for throwing). The compound logically describes a flat, circular medium designed specifically for storing and playing back moving visual content, directly linking the ancient concepts of seeing and a round object to a specific technological format.

Structure: video (relating to visual images) + disc (a flat, thin, round object) - video: From Latin 'vidēre' (to see). In English, a combining form meaning relating to the recording, transmitting, or receiving of visual images. - disc: From Latin 'discus' (a circular plate, quoit).
