What does notifier mean?
A notifier is someone or something that communicates news, warnings, or other important information to another person. The term can refer to a person who formally informs others, such as an official announcing a change, or to a device or software program that alerts a user when something happens. In computing, notifiers are commonly associated with desktop alerts, email, push messages, and other systems that bring information to the user’s attention. Unlike a notification, which is the message or alert itself, a notifier is the agent that delivers or displays it. The word is useful when the source or mechanism of communication matters, as well as in technical descriptions of software and notification systems.

Where does notifier come from?
Notifier is an English formation based on notify plus the suffix -er, meaning a person or thing that performs the action of notifying. Notify comes through Old French notifier from Latin notificare, a compound of notus, meaning known, and facere, meaning to make. The same Latin root also underlies related English words such as notification, notifiable, and notice.
