Definitions
A prima donna diva refers to a person, often in the performing arts, who is highly talented and demands special treatment, often exhibiting a sense of entitlement or arrogance. The term is derived from the Italian phrase 'prima donna,' meaning 'first lady,' typically used to describe the lead female singer in an opera, while 'diva' emphasizes the person's glamorous and sometimes temperamental nature.
