'anabaptist' originates from Greek, specifically the word 'anabaptizein,' where 'ana-' meant 'again' and 'baptizein' meant 'to baptize.'

'anabaptizein' transformed into the Medieval Latin word 'anabaptista,' and eventually became the modern English word 'anabaptist.'

Initially, it meant 'one who baptizes again,' but over time it evolved into its current meaning of 'a member of a Protestant sect advocating adult baptism.'
