Decoy originates from the Middle French word 'decoyer', meaning to lure or entice. The term is derived from 'de-' (meaning from) and 'coyer' (meaning to set a trap or lure). Thus, a decoy is something that is used to lure or attract, often in a deceptive manner.
Think of something that is used to 'lure' ('coyer') someone 'from' ('de-') their original path — that's why a decoy is something that attracts attention away.
