'subscriber' originates from Latin, specifically the word 'subscribere,' where 'sub-' meant 'under' and 'scribere' meant 'to write.'

'subscribere' transformed into the Old French word 'subscrivre,' and eventually became the modern English word 'subscribe' through Middle English.

Initially, it meant 'to write underneath,' but over time it evolved into its current meaning of 'to sign up for a service or publication.'
