theodicy (n.)

wife of Orpheus in Greek mythology, from Latinized form of Greek Eurydikē, literally "wide justice," from eurys "wide" (see eury-) + dikē "custom, usage; justice, right; court case," "custom, usage," and, via the notion of "right as dependent on custom," "law, a right; a judgment; a lawsuit, court case, trial; penalty awarded by a judge," from PIE *dika-, from root *deik- "to show," also "pronounce solemnly."

word-forming element of Greek origin meaning "god, gods, God," from Greek theos "god," which is reconstructed to be from PIE root *dhes-, forming words for religious concepts, such as Latin feriae "holidays," festus "festive," fanum "temple."
