'notifier' originates from the Latin word 'notificare', where 'notus' meant 'known' and 'facere' meant 'to make'.

'notificare' transformed into the Old French word 'notifier', and eventually became the modern English word 'notifier'.

Initially, it meant 'to make known', but over time it evolved into its current meaning of 'a device or person that provides notifications'.
