The Oxford English Dictionary difines Pagan as: -
· n. a person holding religious beliefs other than those of the main world religions.
· adj. of or relating to pagans or their beliefs.
– DERIVATIVES paganish adj. paganism n. paganize (also paganise) v.
– ORIGIN ME: from L. paganus ‘villager, rustic’, from pagus ‘country district’; L. paganus also meant ‘civilian’, becoming, in Christian L., ‘heathen’.
That's good enough for me.
