Baptist → It is derived from the Greek word "baptizō" (meaning to immerse or dip) and the suffix "-ist" (meaning one who practices or is concerned with). The term "Baptist" refers to one who practices baptism, specifically by immersion.
Think of someone who 'immerses' ('baptizō') others in water as a religious practice — that's why a 'Baptist' is someone who performs baptisms.
