Past Participle: disappeared
Disappeared is formed from "dis-" (meaning apart) and "appear" (from Latin "apparere", meaning to come into view). The word describes the action of something moving away from view or becoming invisible.
Think of something that has 'moved away' ('dis-') from being 'visible' ('appear') — that's why disappeared means something is no longer seen.
