Answer:
Monotheistic
Step-by-step explanation:
Mono means one
theistic means relating to or characterized by belief in the existence of a god or gods.
So more than one god would be called polytheistic
Poly is a prefix meaning “many,” as in polygon, a figure having many sides.
theistic means relating to or characterized by belief in the existence of a god or gods.
So as you can see, just look at the first part of the word and you can see whether it is multiple or one. :)
