'anabaptism' originates from Greek, specifically the word 'anabaptismos,' where 'ana-' meant 'again' and 'baptismos' meant 'baptism.'

'anabaptismos' transformed into the Latin word 'anabaptismus,' and eventually became the modern English word 'anabaptism.'

Initially, it meant 'rebaptism,' but over time it evolved into its current meaning of 'a movement advocating adult baptism.'
