Earthbound → It is formed from "earth" (from Old English *eorþe*, meaning the ground or soil) and "bound" (from Old English *bund*, meaning tied or confined). The word "earthbound" describes something that is tied or confined to the earth or ground.
Think of being 'tied' ('bound') to the 'ground' ('earth') — that's why earthbound means confined to the earth.
