'subscribe' 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 or sign,' but over time it evolved into its current meaning of 'to agree to receive or participate in something.'
