Etymology: "Notifier" is a plain English formation: the verb "notify" with the agent suffix "-er" attached, meaning something or someone that performs the act of notifying. The verb itself comes from Latin "notificare," built from "notus" ("known") and "facere" ("to make"), so the word's core idea is literally "making known." The suffix has a longer ancestry than the verb. The "-er" ending descends from Old English "-ere," which goes back through Proto-Germanic and the Latin "-arius" family, and reached English partly through Old French "-ier." Words like "baker" and "writer" share this same pattern, so "notifier" simply extends an old and productive English habit to a newer verb. The sense has shifted a little over time. Early agent nouns in "-er" named people who did an action, but "notifier" is now often applied to machines and software, such as a phone that buzzes when a message arrives. The word follows the common modern pattern of giving an action-doer to devices that do the work automatically.
