pager

The word "pager" is a modern compound formed from the English verb "page," meaning to summon someone via a public announcement system, and the agentive suffix "-er." The verb "page" itself derives from the noun "page," referring to a young attendant or messenger, which entered English from Old French and ultimately from Latin "pagius," possibly meaning a servant. The semantic logic is direct: a "pager" is a device that performs the function of "paging" or summoning its bearer by receiving a signal. This technological term thus builds upon the ancient concept of a messenger, adapting it for electronic communication.

Structure: page (to summon) + er (agent suffix) - page: From Old French/Latin, meaning a servant or a message. In this context, it functions as a verb root meaning "to summon or call (as if a servant)." - er: A native English agent suffix, indicating a person or thing that performs an action.
