Beeper → The word is formed from "beep" (an onomatopoeic term representing a short, sharp sound) and the suffix "-er" (meaning a person or thing that performs an action). A beeper is a device that makes a beeping sound, typically used to alert or notify someone.
Think of the sound 'beep' that the device makes, and remember that a 'beeper' is something that makes that sound to alert you.
