Coppery → It is formed from "copper" (from Old English "coper", meaning a reddish-brown metal) and "-y" (a suffix used to form adjectives indicating a characteristic). The word "coppery" describes something that has the color or characteristics of copper.
Think of the reddish-brown metal 'copper' — the '-y' at the end indicates that something has the quality of copper, so 'coppery' means having the color or characteristics of copper.
