Vibrator → It is formed from "vibrat-" (from Latin "vibratus", meaning to shake or quiver) and "-or" (a suffix used to indicate an agent or something that performs an action). The word "vibrator" refers to something that causes shaking or quivering motion.
Think of something that 'shakes' or 'quivers' ('vibrat-') — that's why a vibrator is a device that creates vibrations.
