Is there a technical difference between the terms torero, toreador and matador?
Torero can be used to describe any of the human participants in a bullfight. Toreador is either an archaic term, or one made up by Bizet for the opera “Carmen” depending on which site one consults. The matador (“killer”) is the main bullfighter, who performs the ritual ending of the fight, including the killing of the bull. There are grades of matador, depending on the age and size of the bulls they fight.
