His idolatry for the celebrity was evident in the way he followed her every move.
Idolatry is formed from "idol" (from Greek "eidolon", meaning image or statue) and "-atry" (from Greek "-atria", meaning worship or practice). The word refers to the worship of idols or images, often in a religious context.
Think of 'idol' as an image that people worship ('-atry' means practice or worship) — that's why idolatry means the practice of worshipping idols.
