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

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

Initially, it meant 'a place for re-baptism', but over time it evolved into its current meaning of 'a place for Anabaptist worship'.
