Physicalist → It is formed from "physical" (from Greek "physikos", meaning natural or pertaining to nature) and "-ist" (meaning one who practices or is concerned with). The word "physicalist" refers to someone who believes in the doctrine that everything is physical or that physical things are the only reality.
Think of someone who is concerned with the 'natural' ('physikos') world — that's why a physicalist is someone who believes everything is physical.
