The principal male singer in an opera or opera company.
- ‘From the late seventeenth century the central male operatic role (primo uomo) in opera seria was sung by a castrato.’
- ‘The prima donna and primo uomo (the hero, generally a castrato) each had at least one large-scale display aria in every act, followed by an exit.’
- ‘In another time he would have plotted with the primo uomo to sing badly and ruin one of my operas, or with others of his ilk to spread rumors about me.’
Italian, literally first man.
