kingly = stately or splendid, as in something or someone resembling, suggesting, or befitting a king; regal royal = of or pertaining to a king, queen, or other sovereign; descended from or related to a king or line of kings; having the rank of a king or queen. sovereign = a monarch - a king, queen, or other supreme ruler; a person who has supreme power or authority; a group or body of persons or a state having sovereign authority. So basically 'kingly' is something/someone that brings to mind the idea of being king, 'royal' is thus a king, queen or even their children (prince or princess) and 'sovereign' is a ruler or group of people who rule. I hope this answers your question. ~Samantha :)
