The word god is said by Etymonline.com to be derived from an ancient protoindoeuropean (PIE) word *ghut- meaning "that which is invoked", and is originally from *gheu(e)- "to call, invoke."
But a god is said to be divine, where did that word come from?
Eus, or ius in addition to indicating good, indicates in Latin a similar property: iustus meaning "upright, righteous, equitable; in accordance with law, lawful; true, proper, perfect, complete" as is from where the the word just is derived.
The word Divine is derived from deity, which is derived from Deus.
The PIE *de means “in the direction of.” The word us, or eus, is from a Greek word indicating “good”, originally from *es meaning “to be”. Thus the word de-(e)us, is the word for god. It indicates “in the direction of good.”
The word Deus indicates “in the direction (of being) good”. What is good?
Eus, or ius in addition to indicating good, indicates in Latin a similar property: iustus meaning "upright, righteous, equitable; in accordance with law, lawful; true, proper, perfect, complete" as is from where the the word just is derived.
One conclusion: Divine is derived from deity, which is derived from Deus indicating "in the direction of being united with true, proper, wholeness and right-use-ness."
Etymonline further notes, "see also Zeus." How does the word zeus relate to the word: god? Zeus, the site tells us, is from root *dyeu- meaning "to shine" in derivatives referring to "sky, heaven, god." The god-sense of this word is originally "shining."
Thus divine science includes the study (as in investigation) of pointing in the direction of reunification with true, proper, wholeness and right-use-ness.
Sometimes playing with words will teach you things.
