Here are some examples:
* Theology: The study of God and religious beliefs.
* Pantheism: The belief that God is everything and everything is God.
* Atheism: The belief that there is no God.
* Monotheism: The belief in one God.
* Polytheism: The belief in multiple gods.
While the suffix "-theo" directly translates to "god," it often implies a connection to the divine or religious aspects of something.
