What does the name 'Medusa' mean?
Medusa means "queen" or "guardian".
Medusa doesn't mean anything she is a woman who has snakes as hair and is said to curse any one who looks into her eyes by turning them into stone. Medusa's name in Greek means guardian or protectress. But when someone calls another person a medusa, that is an insult similar to calling someone an evil person. Another answer Robert Graves, in the Greek Myths, gives the etymology of Medusa to mean cunning.
