KK: /ˈpeɪdʒər/
A small device that receives messages and alerts the user with sounds or vibrations, often used before mobile phones became common.
He carried a pager to receive important messages while he was away from his desk.
Pager → The word 'pager' is derived from the verb 'page' (from Old French *pager*, meaning to turn the pages of a book or to summon) combined with the suffix '-er' (meaning a person who). A pager is a device that summons or alerts a person.
Think of someone who 'summons' or 'alerts' you — that's what a pager does, as it comes from the word 'page' meaning to call or summon.
