Idolatrously → It is formed from "idol" (from Greek "eidolon", meaning image or statue) and "-atrous" (a suffix indicating a quality or condition) combined with "-ly" (meaning in a manner). The word describes the manner of being excessively devoted to an idol or image, often in a religious context.
Think of 'idol' as an image or statue that someone is devoted to, and '-ly' means in a manner. So, idolatrously means acting in a manner of excessive devotion to an idol.
