Also here's an excerpt from the site-The word "monotheism" is made up of two parts, from the Greek. "Mono" is a form of "monos," which means "single, alone" and "theism," which is a form of "theos" meaning "a god." So, "monotheism" literally means "one god." "Theism" is also from the Greek. Over time, "theism" has come to mean "belief in a diety"— coined in the 1670s.
