'program' originates from Greek, specifically the word 'programma,' where 'pro-' meant 'before' and 'gramma' meant 'something written.'

'programma' transformed into the Latin word 'programma,' and eventually became the modern English word 'program' through Old French.

Initially, it meant 'a written public notice,' but over time it evolved into its current meaning of 'a set of instructions for a computer.'
