'prologue' originates from Greek, specifically the word 'prologos,' where 'pro-' meant 'before' and 'logos' meant 'word or speech.'

'prologos' transformed into the Latin word 'prologus,' and eventually became the modern English word 'prologue' through Old French.

Initially, it meant 'a speech before a play,' but over time it evolved into its current meaning of 'an introductory section of a work.'
