Etymology: "Buzzer" is a straightforward formation: the verb "buzz" with the agent suffix "-er" attached, so a buzzer is literally a thing that buzzes. "Buzz" itself is imitative, its sound echoing the humming or vibrating noise it names, and it has been in English long enough to take on that agent ending freely. The "-er" ending has a longer pedigree, descending from the Latin "-arius", which passed through Old French "-ier" and Middle English "-er" before settling into English as a productive way to name a device or a person associated with an action. The surprise lies less in the origin than in how far the sense has travelled. A buzzer began as a sound, and the name simply followed the noise: any object producing that drone could be called one. Over time the term narrowed to the electrical signal familiar from game shows and sports arenas, where the harsh tone announces that an answer is wrong or that time has run out.
