idolatry

Inherited from Middle English ydolatrie, from Old French idolatrie, from Ecclesiastical Latin īdōlatrīa, from Late Latin īdōlolatrīa, from Ancient Greek εἰδωλολατρίᾱ (eidōlolatríā, “worship of idols”), back-formation from εἰδωλολάτρης (eidōlolátrēs), from εἴδωλον (eídōlon, “idol”) & λάτρις (látris, “worshipper”) or λατρεύω (latreúō, “to worship”), from λάτρον (látron, “payment”). Equivalent to idol + -latry. Cognate with Modern French idolâtrie, Italian idolatria, Occitan ydolatria, Portuguese idolatria, and Spanish idolatría. Displaced native Old English dēofolġield (literally “devil worship”).
