deva (n.) Look up deva at
"god, good spirit" in Hindu religion, from Sanskrit deva "a god," originally "a shining one," from *div- "to shine," thus cognate with Greek dios "divine" and Zeus, and Latin deus "god" (Old Latin deivos); see Zeus.

Fem. form devi is used for "goddess," also (with capital D-) for the mother goddess in Hinduism. Hence, also, devadasi "temple dancing girl," literally "female servant of a god," from dasi "slave girl." Also Devanagari, the formal alphabet of Sanskrit writings, perhaps originally "divine city script," from nagara "city."
