KK: /ˈvaɪdiˌoʊˌdɪsk/
A type of optical disk that contains recorded video, often used for playing movies on a television.
We watched a classic film on a videodisc last night.
Videodisc → It is formed from "video" (from Latin "videre", meaning to see) and "disc" (from Latin "discus", meaning a flat, circular object). The word "videodisc" refers to a flat, circular object that contains visual content to be seen.
Think of 'seeing' ('videre') something on a 'flat circular object' ('disc') — that's what a videodisc is for.
