Otherworldly → It is formed from "other" (from Old English "ōther", meaning different or another) and "worldly" (from "world" which comes from Old English "weorold", meaning the earthly realm). The word "otherworldly" describes something that is different from or beyond the earthly realm, often relating to the supernatural or spiritual.
Think of 'other' as something 'different' and 'worldly' as relating to the 'earthly realm'. This helps you remember that 'otherworldly' refers to something that is beyond or different from our earthly experience.
