Supervirtuoso → It is formed from "super-" (meaning above or beyond) and "virtuoso" (from Italian, meaning a person highly skilled in music or another artistic pursuit). The word "supervirtuoso" refers to someone who is exceptionally skilled or talented, surpassing the usual level of virtuosity.
Think of someone who is 'above' ('super-') the usual level of skill in music or art ('virtuoso') — that's why a supervirtuoso is an exceptionally talented individual.
